Through Beam Sensors

The transmitter and the receiver are enclosed in separate housings with Through Beam Sensors. These are mounted so that the light beam emitted by the transmitter strikes the lens at the receiver. wenglor Through Beam Sensors are available with laser light, red light or infrared light. If the active light beam between the transmitter and the receiver is interrupted, the output is switched. Transmitters are equipped with a test input and can thus be checked for correct functioning. The controller works together with the light barriers SA250/EA250 and avoids a mutual influence of the sensors.

Applications

• Edge recognition Object counting
• Monitoring openings
• Drill breakage monitoring
• Recognition of extremely small parts

Through Beam Sensors with Laser Light

The Light Spot is readily visible – even over great distances – allowing for easy adjustment and initial start-up. The use of a very fine light beam ensures a small diameter spot. Thus enabling the secure recognition of extremely small parts.

Adjustable focal point ZD600/ZW600/YO99/OSD404

These Through Beam Sensors with laser light are equipped with an adjustable focal point. 　 　 　 　

Through Beam Sensors with Red Light

Thanks to their visible red spot, these sensors are quite easy to adjust, making initial start-up very simple.

Through Beam Sensors with Infrared Light

These sensors have an invisible spot. However, infrared light is better able to penetrate contamination or objects.

EA250/SA250

These Through Beam Sensors are designed for use in combination with the wenglor LV250 Through Beam Sensor controller. Thanks to the high ratio they also work securely in a very dirty surrounding. Use of the wenglor controller rules out any possible interactive influence between light barriers.

Interface

Sensor functions can be activated and scanning results can be acquired via the RS-232 interface.

Adjustments

Adjustments are performed with a potentiometer. With Teach-In versions, adjustments are made with the appropriate keys, externally or via the RS-232 interface.

Laser Class

Sensors with laser class 1 have the smallest laser capacity according to EN 60825-1 and make warning signs redundant. Due to their higher light capacity, sensors with laser class 2 achieve better specifications.
