Key Performance and Interference Resistance

• The 36 beam axes create a dense protective field across the full 700 mm detection height.
• The optical design holds the effective aperture angle within ±2.5° at 3 m or more.
• Interference prevention supports up to 2 GL-R systems through a Channel A/B switch for optical sync.
• Wire synchronization manages interference automatically, so setup stays quick and simple.
• The detection mode turns the output ON when no interruption exists in the detection zone.
• Reverse-current, per-output short-circuit and surge protection circuits guard each OSSD line.
• Residual voltage stays at max. 2.5 V ON and max. 2.0 V OFF with a 5 m cable.
• Leakage current remains at max. 200 µA, with capacitive load up to 2.2 µF and load wiring resistance max. 2.5 Ω.
• The supplemental AUX, error and muting-lamp output carries a non-safety load of max. 50 mA.
• This model offers no built-in ports or communication protocols, which keeps the wiring clean.

Installation Guide

• Mount the transmitter and receiver facing each other and align them within the ±2.5° aperture limit.
• Keep the detecting distance between 0.2 m and 15 m to match the rated response performance.
• Choose optical synchronization for flexible layout or wire synchronization for automatic interference handling.
• Connect a 24 VDC Class 2 supply with ripple of 10% or less to both units.
• Wire the OSSD outputs according to the cable type, since the cable sets PNP or NPN behavior.
• Keep load wiring resistance at max. 2.5 Ω and confirm the load stays within 500 mA.
• Avoid strong ambient light above 3,000 lux from incandescent lamps or 20,000 lux from sunlight.
• Verify the IP65/IP67 seal after mounting in wet or dusty production areas.
