Product description
Two types of sensors can be connected to the safety evaluation de-
vice UE 401:
L 4000 with a scanning range of up to 60 m,
L 400 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 UE 401.
The sensors are fitted in cylindrical housings with an external thread.
These are metal housings with thread M30x1.5 on the L 4000 sen-
sors and plastic/metal housings with thread M18x1 on the L 400
sensors.
Sender and receiver are each equipped with an LED for operational
checks:
