Key Performance and Environmental Resistance

• The GL-R79F covers a 0.2 to 10 m detecting distance for varied machine layouts.
• Infrared LED emission at 870 nm keeps detection stable under typical factory lighting.
• The Type 4 ESPE / AOPD design supports Category 4 and PLe safety architectures.
• Optical or wire synchronization depends on your chosen wiring method.
• Interference prevention supports up to 2 GL-R systems through Channel A/B switching.
• The IP65/IP67 housing resists dust and water jets in demanding production areas.
• Reverse-current, short-circuit, and surge protection circuits guard each output.
• A ±2.5° effective aperture angle helps maintain alignment over long distances.
