For your safety, read and follow the considerations written in the instruction manual, other manuals and Autonics website. Keep this instruction manual in a place where you can find easily. The specifications, dimensions, etc. are subject to change without notice for product improvement. Some models may be discontinued without notice. Follow Autonics website for the latest information.

Safety Considerations

Observe all ‘Safety Considerations’ for safe and proper operation to avoid hazar
symbol indicates caution due to special circumstances in which hazards may occur.

Warning Failure to follow instructions may result in serious injury or death .

Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, )
System manager means followings;
- a personnel who is fully aware of installation, setting, operation, and maintenance of the product
- a personnel who well observes standard/regulation/statute on the product by type of machine the product installed in and nation/region the product used in Machine user means a personnel who is appropriately trained about using machine by the system manager, so that machine user can operate the machine correctly. System manager has duty to train the machine user a bout operation of the product. Machine user has to report directly to the system manager when unusual status has been found while system is operating. Failure to follow this instruction may result in personal injury, economic loss or fire.
The product has to be installed, set, and combined with machine control system by the qualified system manager. Failure to follow this instruction may result in personal injury due to unintended operation and unstable detection.
Before using the product, check that function of the product operates as intended while machine is turned off after installation. Failure to follow this instruction may result in personal injury due to unintended operation and unstable detection.
Do not use the unit in the place where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact, salinity, moisture, or steam, or dust may be present Failure to follow this instruction may result in explosion or fire.
Do not disassemble or modify the unit Failure to follow this instruction may result in personal injury or fire due to loss of safety function.
Do not defeat, tamper, modify, or bypass the switch and enter the door. Failure to follow this instruction may result in personal injury.
Check whether machine is stopped or not when the door is opened. Failure to follow this instruction may result in personal injury.
Check the installed status of the switch, operating status of the switch, and signs of damage, modification, tampering of the switch at the following situation and on a weekly basis.
- when operating the safety system at first
- when replacing component of the system
- when the system has not been operated for a long time Failure to follow this instruction may result in personal injury due to malfunction of the product and safety function.
Do not connect, repair, inspect, or replace the unit while connected to a power source. Failure to follow this instruction may result in fire.
Check ‘Connections’ before wiring. Failure to follow this instruction may result in fire.
Keep away from high voltage lines or power lines to prevent surge and inductive noise, and make cable as short as possible. In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input signal line. Do not use near the equipment which generates strong magnetic force or high frequency noise. Failure to follow this instruction may result in personal injury due to malfunction of the product and safety function.

Caution: Failure to follow instructions may result in injury or product damage.

Use the unit within the rated specifications. Failure to follow this instruction may result in fire or product damage.
Use a dry cloth to clean the unit, and do not use water or organic solvent. Failure to follow this instruction may result in fire.
Make cable as short as possible, and keep the length of the cable within 100m when extent the length of the cable. Failure to follow this instruction may result in malfunction of the product and safety function due to surge.
When wiring two or more products in series, keep the total length of the cable within 100m. Failure to follow this instruction may result in malfunction of the safety function due to voltage drop.
When installing two or more product adjacently, give at least 26mm interval. Failure to follow this instruction may result in malfunction due to mutual interference.
Do not install the switch and actuator on the magnetic object. Use bolt and nut of stainless steel or non-magnetic material, when installing the switch and actuator. Failure to follow this instruction may result in malfunction or affect sensing distance.
Do not use the switch as a guard door stopper. Install separate mechanical stopper. Failure to follow this instruction may result in product damage.

Cautions during Use

Follow instructions in ‘Cautions during Use’ Otherwise, it may cause unexpected accidents.
Use the switch with the dedicated actuator and controller. Do not use the switch with another actuator or controller randomly. The switch is cannot be used without the controller (SFC-N322).
Power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
When using switching mode power supply to supply the power, ground F.G. terminal and connect a condenser between OV and F.G. terminal to remove noise.
This unit may be used in the following environments.
- Indoors (UL Type 1 Enclosure)
- Altitude max. 2,000 m – Pollution degree 3
- Installation category II
Install the unit correctly with the usage environment, location, and the designated specifications.
When installing the product, tightening the screw of M4 x 20 mm with the tightening torque of 0.8N.m.
Installing more than 2 non-contact door switches closely may result in malfunction due to mutual interference.
Do not impact on the switch and excessively bend the cables.
Install the switch to the sensing surface of the switch and the actuator be exactly parallel.
Install the switch to the direction as below with the consideration of moving directions of the actuator.
Install the switch and actuator with a gap of minimum 1mm between them.
Install the switch at the adjoining wall of the guard door and the actuator at guard door.

Safety status in case of error: the switch does not have an internal error recognition function, so it cannot maintain a safety status in the event of error. Error recognition is processed in the connected controller (SFC-N322).

Operation Distance

Operating distance represents the distance between the sensing surface of switch and that of actuator.
Operating distance can be differed according to the moving direction of actuator from the switch. (at ambient temperature of 23 °C)
The operating distance may be affected by metal or magnetic substances which is placed closely to the switch.
