Overview
The Euchner TP3-2131A024MC1743 (order number 084285) is an electromechanical safety switch with guard locking and integrated door position monitoring. This proven plastic-housing TP-series switch provides spring-force guard locking controlled by a 24V solenoid, making it ideal for protecting access to hazardous machinery in CNC machine centers and industrial automation equipment. The switch features manual escape release from the rear and auxiliary release on the front for emergency situations.
Key Features
- Guard locking with spring force engagement; solenoid-controlled release via 24V AC/DC
- Door position monitoring contact for feedback confirmation
- Escape release on rear (short shaft, C1743) for tool-free emergency manual unlock from the danger zone
- Auxiliary release on front for additional access control
- Cable entry via M20 × 1.5 connector; horizontally and vertically adjustable in 90° steps
- Increased horizontal overtravel for door clearance and reduced mechanical stress
- Compact plastic enclosure suitable for temperature-resistant and corrosion-resistant applications
Technical Specifications
- Solenoid Operating Voltage: AC/DC 24 V (+10%, −15%)
