Overview
The L21 single-beam photoelectric safety switch consists of a sender and receiver. The test input on the sender allows direct functional tests. Performance level PL c in acc. with EN ISO 13849-1 or Type 2 in acc. with IEC 61496 can be achieved in conjunction with a safety controller. Suitable safety controllers are, for example, Flexi Classic or Flexi Soft. Color LEDs provide local information about the operational status.
The required range can be selected from various device versions. All versions are suitable for outdoor applications and enable even complex safeguarding tasks to be accomplished by using deflector mirrors.
