The L41 is a type 4 （IEC61496） cascadable single-beam photoelectric safety switch comprising of a sender and a receiver
The correct function of the L41 can be checked with the aid of the test input on the sender
Integrated testing means sensor signals are now directly available for a variety of control related logics and functions e.g
AND/OR, Muting or Bypass Colour LEDs provide in-situ information on operational status Numerous areas of operational use, IP67 rated for outdoor applications and sub-zero operating capability Nickel plated brass housing Inputs/outputs compliant with EN 61131 Direct connection to safe controllers and thus evaluation without detours e.g
UE410 Flexi Classic
Performance levels up to PL e in accordance with EN ISO 13849-1 and SILCL3 （IEC62061）, SIL3 （IEC61508） can be achieved Applications include： Robots, processing machines, palletiser systems, machining centres and high bay warehouses
