Keyence GL-R20L

The Keyence GL-R20L is a high-performance body-protection light curtain designed to ensure maximum safety in industrial environments. Featuring 20 optical axes, this unit provides a detection capability of ø45 mm and a total length of 800 mm, making it ideal for safeguarding large areas. The detection height of 760 mm and protection height of 845 mm ensure comprehensive coverage.

Equipped with an infrared LED light source (870 nm), the GL-R20L offers a detecting distance range of 0.2 to 15 meters. The effective aperture angle of ±2.5° ensures precise detection even at longer distances. The unit supports both optical and wire synchronization, preventing mutual interference in up to two GL-R systems.

The control output includes two transistor outputs (PNP or NPN), with a maximum load current of 500 mA. The supplemental AUX transistor outputs provide additional flexibility for non-safety-related applications. The GL-R20L also features robust protection circuits, including reverse current protection, short-circuit protection, and surge protection.

Designed to meet stringent safety standards, the GL-R20L complies with IEC61496-1, EN61496-1, UL61496-1 (Type 4 ESPE), and other relevant standards, ensuring reliable performance in critical applications. The unit's environmental resistance is enhanced by an IP65/IP67 enclosure rating, making it suitable for use in harsh industrial conditions.
