The Laser Barrier VL/VRG resolves all detection problems that may arise in the most diverse types of industry, for example heavy industry (steel), handling and transport, etc. It is particularly recommended for the following applications:
The emitter VL unit emits a high intensity, visible beam of modulated red laser light. This beam is received by a photosensitive diode fitted with an optical filter and whose signal is processed by the incorporated circuitry of the receiver VRG. The output changes state depending on whether the modulated beam is interrupted or not. Beam modulation, special optical filter and automatic correction make the sensor insensitive for ambient light.
Commissioning and Alignment
The visible, intense and highly directive laser beam makes the setting up of the optical barrier VL/VRG simple and rapid.
To align the sensor, use the following procedure:
This procedure guarantees a precision for the detection of approx. 1 cm for a product of cross-section greater than 4 cm.
The accuracy of the detection can be increased by optimizing the detection threshold adjustment with the sensitivity potentiometer.
