Overview

Universal use up to type 4 with safe control solutions from SICK

The L41 single-beam photoelectric safety switch consists of a sender and a receiver. The test input of the sender supports direct functional testing. Performance level PL e to EN ISO 13849 or Type 4 to IEC 61496 can be achieved in conjunction with an evaluation unit. Suitable evaluation units include Flexi Classic or Flexi Soft. Color LEDs provide local information about the operational status. The required sensing range can be selected from various device versions. All devices are suitable for applications in challenging ambient conditions and enable even complex protection tasks to be accomplished by using deflector mirrors.
