CEM-I2-AR-U-C40-SH-124937 (Order no. 124937)

Description

Unicode evaluation

Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in. Only the last actuator taught-in is detected.

Guard locking type

CEM‑I2

Guard locking actuated by energy ON and released by energy OFF.
