Laser Barrier VL-VRG

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for the VL/VRG Laser Barrier, a through-beam laser sensor designed for harsh industrial environments. It is capable of detecting both hot and cold products over a distance of up to 80 meters.

Special Features:

Intense, highly directive visible red laser diode beam.
Insensitive to ambient light with adjustable sensitivity.
LED indicator for receiver operation and alarm signals for dirty lenses or high internal temperatures.
Modular construction for easy maintenance and optional water-cooling jackets for high-temperature environments.

Applications: Suitable for various industries, including heavy industry and transport, the laser barrier is particularly effective in environments where precise detection is required.

Commissioning and Alignment: The setup involves aligning the VL emitter and VRG receiver using the visible laser beam. The procedure ensures detection precision of approximately 1 cm for products with a cross-section greater than 4 cm.

Performance Specifications:

Maximum distance: 80 m between emitter and receiver.
Detection accuracy varies with distance: ±1.5 mm at 2 m and ±5 mm at 6 m.
Emitter power: 1 mW, Laser Class 2, wavelength 635-670 nm.

Technical Characteristics:

Receiver models include VRG with various output options (transistor, relay, solid state relay).
Electrical characteristics include short circuit protection and various switching capacities.
Operating voltage ranges from 24 V DC to 240 V AC, with power consumption of 10 VA or 8 W.
Protection rating: IP 67 with air purging and optional water cooling for temperatures up to 120 °C.

Connection and Order Reference: Connections are available via connector or terminal block, with specific order references provided for different configurations.
