Detection Performance and Environmental Resistance

• The ø25 mm detection capability protects hands before they reach dangerous machine parts.
• A 0.2 to 15 m detecting distance covers compact openings and long production lines alike.
• The 6.6 ms response time keeps stopping distances short and predictable.
• Infrared LEDs at 870 nm resist ambient light up to 20,000 lux sunlight.
• Optical or wire synchronization lets you match the wiring scheme you already use.
• Interference prevention supports up to 2 GL-R systems on one site.
• IP65/IP67 protection rating handles dust, coolant spray, and washdown exposure.
• The -10 to +55 °C operating range suits most factory floors without extra cooling.

Installation Guide

• Mount the transmitter and receiver face to face at the 0.2 to 15 m working distance.
• Align both units so the effective aperture angle stays within ±2.5° at 3 m or more.
• Choose optical synchronization or wire synchronization before you terminate the cables.
• Connect the 24 VDC ±20% Class 2 supply and keep ripple below 10% P-P.
• Wire the two OSSD outputs to the safety relay or machine stop circuit.
• Use the AUX, error, or muting-lamp output for status signaling at max. 50 mA.
• Set the Channel A/B switch when you run two GL-R systems side by side optically.
• Verify the detection zone stays clear and the OSSD turns ON only with no interruption.
