Key Performance and Environmental Resistance

• The GL-R24H detects hands with a ø25 mm capability across a 460 mm detection height.
• A 7.0 ms response time supports fast stopping performance for machine safety circuits.
• The infrared LED at 870 nm resists ambient light up to 20,000 lux sunlight.
• Optical synchronization prevents cross-talk between two GL-R systems in one area.
• The IP65/IP67 rating withstands dust and water jets in demanding factory environments.
• Reverse-current, short-circuit and surge protection circuits safeguard each output.
• The AUX, error and muting-lamp output supports diagnostics with a 50 mA load.

Installation Guide

• Mount the transmitter and receiver facing each other with the beam axes aligned.
• Keep the effective aperture angle within ±2.5° when the operating distance exceeds 3 m.
• Choose optical synchronization for simple wiring or wire synchronization for fixed channels.
• Set the channel A/B switch when two GL-R systems operate near each other.
• Connect the 24 VDC supply with 10% or less ripple and observe Class 2 requirements.
• Wire the two OSSD outputs to your safety relay and keep load current below 500 mA.
• Verify the detection zone stays clear and the OSSD turns ON only without interruption.
