wenglor I08H051 Inductive Sensors With Increased Switching Distances Instruction Manual

wenglor I08H051 Inductive Sensors With Increased Switching Distances

Product Information

The product is an inductive sensor with two variants: one with a standard switching distance and another with an increased switching distance. It is designed to detect the position of metallic objects by generating a magnetic field using a coil located underneath the sensing face. When metal objects, such as steel, aluminum, or brass, approach the sensor, eddy currents are generated within the magnetic field and measured by the sensor. Once the approaching metal object reaches the selected switching distance, the output of the sensor is switched.

Installation Instructions

1. Installation Instructions in Accordance with Standard

This clearance applies to installation in air. If the sensors are installed within an attenuating material (e.g. steel), this distance is reduced. Testing in the application is required in order to determine the exact distance.

C| Minimum distance from the sensing face of the inductive sensor to the damping material (e.g. steel).

Distance C does not make reference to the object to be detected, but rather to the background. The object to be detected is detected within the switching distance.

D| Minimum dimension by which the sensor (sensing face) must protrude from the damping material (e.g. steel).
8 × Sn| Installation opposite each other Two identical sensors must be mounted at this minimum distance.
2. Installation instructions for sensors with weproTec

• weproTec is the abbreviation for wenglor proximity switch technology, an innovative, patented wenglor technology for inductive sensors.
• Inductive sensors with weproTec can be mounted very close to each other ( installation dimension B1) or opposite one another (1.5 ×Sn). No reciprocal influence occurs among the sensors within the specified zones.
• The installation instructions in accordance with the standard (section “5.3.1 Installation Instructions in Accordance with Standard” on page 11) are also valid.
• weproTec has the following sensors: I08xxxx, I12xxxx, I18xxxx, I30xxxx, I1AHxxx, I1BHxxx, I1CHxxx, I1DHxxx, I1QHxxx

This clearance applies to installation in air. If the sensors are installed within an attenuating material (e.g. steel), this distance is reduced. Testing in the application is required in order to determine the exact distance.

B1| Additional minimum distance between two inductive sensors.

This clearance applies to installation in air. If the sensors are installed within an attenuating material (e.g. steel), this distance is reduced. Testing in the application is required in order to determine the exact distance.

C| Minimum distance from the sensing face of the inductive sensor to the damping material (e.g. steel).

Distance C does not make reference to the object to be detected, but rather to the background. The object to be detected is detected within the switching distance.

D| Minimum dimension by which the sensor (sensing face) must protrude from the damping material (e.g. steel).
1.5 × Sn| Installation opposite each other Two identical sensors must be mounted at this minimum distance.

Switching distance

• The switching distance described in the data sheet is the nominal switching distance Sn according to the standard.
• The switching distance refers to a standard measuring plate (material: steel, thickness: 1 mm, side lengths: 3× Sn or outside diameter sensor).
• The switching distance according to the standard is further differentiated into:
  • Effective switching distance Sr
  • Useable switching distance Su
  • Working distance Sa

NOTE!

•  If the objects in the application are smaller than the standard measuring plate, the switching distance is also reduced.
• The correction factor of the sensor for certain materials also influences the switching distance and must be observed.
• The sensor should be mounted at a working distance Sa or less to the object.

Electrical Connection

• Wire the sensor according to the connection diagram (for the connection diagram see packaging or product detail page at www.wenglor.com)

• Connect the sensor to 10…30 V DC
  DANGER!

  • Risk of personal injury or property damage due to electric current.
  • Live parts may cause personal injury or damage to equipment.
    The electric device may be connected by suitably qualified personnel only

| Reduce the distance between the sensor and the object

• Distance must be < 0.8 × Sr min

Example

Object distance < 0.71 mm

Error| Short circuit| Check the electrical wiring and eliminate the short circuit
