Application      
The V3 reflecting optical barrier resolves all detection problems that may arise in the most diverse types of industry, for example heavy industry (steel), handling and transport. The use of visible emission greatly facilitates setting up of the barrier.

General Descripton       Up
The V3 is a self-contained sensor including:

• a power supply unit with transformer
• an optical unit equipped with light emitting diode and reception photodiode
• an amplifier with output interface (solid state or relay output)
• connection via a terminal block with protective cover or via a connector
• modular design

Working Principle     Up
A beam of visible modulated light is emitted by the diode emitter and reflected back along the same path by a prism reflector placed opposite the sensor. The reflected beam is focused onto the photodiode which outputs an electrical signal to the amplifier circuit. Depending on whether the modulated beam is interrupted or not, the output is switched. Modulating the emission and automatic correction for ambient light in the amplifier circuit renders the sensor insensitive to ambient light.

Special Features    Up

• Visible red diode emission
• Insensitivity to ambient light
• A sensitivity potentiometer for adjustment of the detection threshold (under the protective cover at the rear of the sensor)
• Jack socket (under the protective cover at the rear of the sensor) providing an output of signal strength as an aid during alignment
• A LED indicator showing operation of the sensor
• An optional water-cooling jacket for use at ambient temperatures greater than 70°C (flow-rate 2 I/min)
• Modular construction allowing rapid maintenance
