Euchner CET3-AR-CRA-AH-50X-SG Non-Contact Safety Switch CET-AR-..., M12 109401
Features
• Safety switch with guard locking and integrated evaluation electronics
• Locking force up to 6,500 N
• Up to 20 switches in series
• Short circuit monitoring
• 2 safety outputs (semiconductor outputs)
• Category 4/PL e according to EN ISO 13849-1
• With 2 plug connectors M12
• Unicode
• Door monitoring output

• Teach-in input
• Approach direction A (delivery state)
Safety Switch
The device may be operated only in conjunction with the actuator CET-A-....
Important: The actuator must be ordered separately.
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.
Solenoid operating voltage
DC 24 V +10% -15%
Guard locking type
CET3 Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid. The door position is also monitored. The door monitoring output OUT D is set to HIGH as soon as the actuator is above the extended plunger (state: door closed, guard locking not active). The output OUT D remains set also with guard locking active.
Switching element
2131 Slow-action switching contact 2 NC + 1 NO + 1 NC (door monitoring contact)
Auxiliary release
This is used for manual release of guard locking from within the danger area without tools. With identification of On/Off position.
