MICRO-EPSILON optoNCDT ILR1171 Fast Laser Distance Sensor Instruction Manual
Intended Use
The optoNCDT ILR1171 is designed for use in industrial and laboratory applications (research and development facilities). It is used for process monitoring in steel works and rolling mills, fill-level measurement, monitoring of moving objects, positioning of cranes and loading equipment, position monitoring of road vehicles and ships, speed measurement of vehicles and ships. The sensor must only be operated within the limits specified in the technical data, see operating instructions, Chap. 3.3. The sensor must be used in such a way that no persons are endangered or machines and other material goods are damaged in the event of malfunction or total failure of the sensor. Take additional precautions for safety and damage prevention in case of safety-related applications.
Warnings
Connect the power supply according to the safety regulations for electrical equipment.
Risk of injury
Damage to or destruction of the sensor
Refrain from using the sensor in an explosive environment.
Damage to or destruction of the sensor and/or other proximate equipment
Cable connectors must not be plugged or unplugged, as long as voltage is supplied. Remember to turn voltage supply off before you begin working on cable connections. The supply voltage must not exceed the specified limits. Avoid shocks and impacts to the sensor.
Damage to or destruction of the sensor
Protect the cables against damage. Do not turn the module on if there is fogging or soiling on its optical parts. Do not touch any of the module’s optical parts with bare hands. Proceed with care when removing dust or contamination from optical surfaces.
Failure of the measuring device
Avoid measurements against the sun or onto surfaces with low reflectivity in very bright environments. Avoid measurements through glass, optical filters, Plexiglas or other translucent materials.
Incorrect measurement
i Information and warning signs must not be removed.
Laser Safety
The optoNCDT ILR1171 works with a semi-conductor laser at a wavelength of 905
nm (invisible/infrared). The maximum optical power is 1 mW. The sensors fall
within laser class 1. The accessible radiation is harmless under predictable
conditions. For class 1 laser devices, impairment of color vision and
disturbances, e.g., from a glare effect, cannot be excluded. Consequently, you
can use Class 1 laser equipment without further protective measures. Lasers of
Class 1 are not subject to notification and a laser protection officer is not
required. The following warning labels must be attached to the cover (front
side) of the sensor housing. The IEC laser warning labels have already been
attached. For other non German speaking countries, an IEC standard label and a
German label are included in delivery and the versions valid for the user`s
country must be attached before the device is put into operation for the first
time.
Sensor with laser labels
The housing of the optical sensors may only be operated by the manufacturer, see operating instructions, Chap. 11. For repair and service purposes, the sensors must always be sent to the manufacturer.

Installation and Assembly, Dimensional Drawings
The sensor optoNCDT ILR1171 is an optical sensor for measurements with
millimetre accuracy.
i Ensure careful handling during installation and operation!
Dimensional drawing optoNCDT ILR1171, dimensions in mm (inches)
The optoNCDT ILR1171 can be screwed on 3 positions:
– front with 2 screws M3
– bottom side with 4 screws M3
– one small side with 3 screws M3
i Mount the sensor only to the existing through-bores on a flat surface. Any
type of clamping is not permitted.
Never exceed the specified torques.
Choose the length depending on the counter piece.
- Recommendation: Test under use conditions!
MICRO-EPSILON recommends using screws with washer and ring washer. The zero point for measurement is identical with the housing front face.
Operating Elements
- n.c.
- Measurement control LED, multicolor
- 12-pin M12-A female connector, type Binder
Operating elements of the sensor optoNCDT ILR1171 The optoNCDT ILR1171 has a measurement control LED. The LED is flashing green during measuring without a failure. The LED is flashing red if a failure is happened.
Pin Assignment
All models share the same type of main connector port/interface.
Connector on the rear side of the sensor
The connector is located on the rear side of the sensor. The assignment of the
power supply/serial interface results from a 12-pole round-type (flange mount)
series 723 connector from Binder.
This connector type guarantees optimized screening and a high IP degree. The
required counterpart is an adequate female cable connector.
MICRO-EPSILON recommends the optionally available supply and output cable
PC1171-x.
Bending radius of the PC1171-x: 47 mm (once); 116 mm (permanent)
Inverse polarity protection is provided. Overvoltage protection is provided up
to a maximum of 42 V DC.
i The shield of the cable should be connected to the connector housing. Open,
unused cable wires must be insulated.
Supply Voltage
Nominal value 24 VDC (10 … 30 V)
Only turn on the power supply after wiring has been completed. Connect the 2
(blue) and 9 (red) inputs on the sensor to a 24 V voltage supply.
i Use the voltage supply only for measuring devices, not for drives or similar sources of impulse interference at the same time.
MICRO-EPSILON recommends using the optionally available PS2020 power supply for the sensor.
Analog Output
The sensor produces a current output of 4 … 20 mA.
i The output may not be used continuously in short-circuit operation without a
load resistor. Continuous short-circuit operation leads to thermal overloading
and thus causes the output to switch off automatically.
Connect the 11 (gray/pink) and 12 (red/blue) inputs on the sensor to a measuring device.
The current impressed in the line is proportional to the measured distance.
You can find more details on this in the analog output section, see operating
instructions, appendix.
i The measured values are always output via the analog output.
Switching Output
Switching outputs Q1 and Q2 show the distance information as logical switching
information. They signalize whether the preset hysteresis switching range is
exceeded or fallen short of.
Thus, they are ideally suitable for direct further processing of monitored
values such as fill level or object detection. Parameterization is done via
the serial interface.
A load resistor of > 150 Ohms/ 6 W (max. supply voltage of 30 V; max. load
current of 0.2 A) must be switched against VDC- (GND of supply voltage) at the
switching output. It is important that the load current of 0.2 A is not
exceeded.
Pin assignment and wiring of switching outputs Q1 and Q2 Q1/Q2 parameterizes
the behavior of the switching outputs. The parameters include the beginning w
of the measuring range (switching threshold) when the output switches, the
length x of the switching range, the switching hysteresis y as well as the
logic behavior z (switching state).
Trigger Input/Output
The optoNCDT ILR1171 trigger could be used as input or output, see operating instructions.
RS422 Connection with USB Converter IF2001/USB
The RS422 interface can be used for configuration as well as for permanent
data transmission, even over longer distances. It is interference-resistant
and suitable for industrial applications. Distances of up to 1200 m are
possible with a twisted-pair cable. For the connection between sensor and PC,
the lines must be crossed.
i Only disconnect or connect the sub-D connection between the RS422 and USB
converter IF2001/USB when no voltage is flowing.
Characteristics
– Maximum input voltage RX+, RX- : ±14 Vmax internally terminated with 120 Ohm
– Output voltage TX: ±2 V, differential at 2 x 50 Ohm
Parameter
– Baud rate 115200 baud
– Start/stop bit: 1
– Data bits: 8

i The RS422 interface is widely used in industrial applications. Use a suitable USB converter, e.g. the optional available IF2001/USB, if your PC/notebook only has USB ports.
Symmetrical differential signals according to EIA-422, not electrically separated from the voltage supply. Use a shielded cable with twisted wires, e. g. PC1171-x, available as an optional accessory.
Quick Guide
Initial Operation
The sensor is ready to use after approx. 2 s, digital accuracy is immediate.
The sensor typically requires a warm-up time of 5 min for reproducible
measurements via the analog output.
Connect the sensor to a PC/notebook via an RS422 converter and connect the
power supply. Launch a terminal program (e.g. Bra@s Terminal, Tera Term,
Putty). The program will now search for connected ILR1171 sensors.
Using the ILR1171 via the Serial Interface with a Terminal Program
The optoNCDT ILR1171 is parameterized via a serial interface. Prerequisite for programming via UART is a connection provided by a terminal program (e.g. Bra@s Terminal, Tera Term, Putty). The set parameters are stored in an EEPROM. When restarting, the last entered data will be available. Basic settings for communication:
Baud rate: 115200
Parity: none
Data bits: 8
Stop bits: 1
Select the appropriate COM port where the sensor is connected to the PC.
