| GL20 and GL40 Infrared Light Curtain Sensors GL20 and GL40 light curtains use parallel infrared transmitter and receiver beams to monitor a detection area. Compare beam pitch, beam count, monitored width, housing dimensions, output and response time. | 38–41 |
Standard GL configuration is listed as a 0.3 m lead plus 2 m cable, four brackets per pair, individual receiver beam-status LEDs, a four-pin M12 connector and a standard 10–30 V DC supply. The detailed page includes the source dimension tables, performance specifications, wiring and application examples. Verify documentation for the exact model before use in a machine-safety function.
The catalog dimension tables use 20 mm and 40 mm beam pitch respectively. Beam count determines monitored width and overall length.
No. Request the certificate and safety documentation for the exact model, then validate the complete machine installation. The page records the catalog reference without assigning an unverified safety type.
