Single-beam photoelectric safety switches
L28

Compact type for optimum integration into safety applications up to type 2

Your Benefits

  • Easy integration due to small, compact designs with maximum sensing range
  • Cost savings due to the facility to connect directly to a safe controller
  • Flexible device integration makes it possible to set up individual access protection solutions
  • Well-suited to extreme ambient conditions such as heat, cold or moisture

Overview

Compact type for optimum integration into safety applications up to type 2

The L28 single-beam photoelectric safety switch consists of a sender and receiver. The test input of 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.
