Product description
Two types of sensors can be connected to the safety evaluation
device UE401:
• L4000 with a scanning range of up to 60 m,
• L400 with a scanning range of up to 5/10 m.
The sensors only comply with IEC 61 496-1 and IEC 61 496-2 in
conjunction with the safety evaluation device UE401.
The sensors are fitted in cylindrical housings with an external thread.
These are metal housings with thread M30x1.5 on the L4000
sensors and plastic/metal housings with thread M18x1 on the L400
sensors.
Sender and receiver are each equipped with an LED for operational
checks:
