CTM-LBI-BR-M-AZ-SA-165517 (Order no. 165517)

Description

Multicode evaluation

Every suitable actuator is detected by the switch.

Guard locking type

CTM‑LBI

Guard locking operated by means of input signal.

This type of guard locking has a function to prevent

  • persons from unintentionally locking themselves inside if the safety door is open in case of a power failure or if the machine is switched off.
  • the deactivation of the activated guard locking in case of a power failure.
