Optical Barrier VE/VR

Product catalog summary

Overview: The document details the specifications and applications of the Optical Barrier VE/VR, designed for harsh environments such as coke plants and rolling mills. It features a through-beam optical barrier capable of detecting hot or cold products over a distance of up to 200 meters.

Specifications:

Visible red diode emission with insensitivity to ambient light.
Cast aluminum case with air purged hood and optional water-cooling plate.
Modular construction for rapid maintenance.
Alarm signal for dirty lenses or high internal temperature.

Components:

Emitter (VE): Includes an optical unit with emitting diode, power supply, terminal block or connector, and lens protection hood.
Receiver (VR): Features a special filter, photodiode, electronics with high current transistor output, and similar protective features as the emitter.

Commissioning:

Adjust light reception by setting the sensitivity potentiometer to max and aligning the emitter for optimal reflection.
Check object detection by moving the object into the beam and observing the LED indicator change.

Performance:

Maximum distance between emitter and receiver: 200 m.
Detection margin varies with distance.

Technical Characteristics:

Outputs include transistor, isolated solid state relay, and relay options.
Electrical characteristics: 2 complementary push-pull outputs, short circuit protection, and various switching capacities.
Response time: 1 ms, with make and break times of 8 ms and 4 ms respectively.
Alarm output for low received light or high internal temperature.

Operating Modes: Different models have specific operating modes and LED indicators for beam interruption and alarm states.

Additional Information:

Operating voltage options and power consumption details.
Protection rating of IP 67 and air purging requirements.
Working temperature range and cooling options.

Dimensions and Connection: Details on dimensions, air and water supply connections, and mounting instructions are provided.
