Features

• Visible red diode emission.
• Insensitivity to ambient light.
• Cast aluminium case with air purged hood for protecting the lens and with water-cooling plate.
• Modular construction allowing rapid maintenance.
• Alignment and checking devices: sensitivity potentiometer, jack socket for aid during alignment, light indicator showing operation.

The VE/VR Optical Barrier resolves all detection problems that may arise in the most diverse types of industry, for example heavy industry (steel), handling and transport, etc.

The emitter VE unit emits a high intensity, visible beam of modulated red 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 VR. The output changes state depending on whether the modulated beam is interrupted or not. The modulating of the emission, the particular characteristics of the optical filter and the automatic correction for ambient light render the sensor insensitive to another source than the one of the emitter.

Presentation
