Why Choose the ABB sense72m Safety Magnetic Switch?
The ABB sense72m 2TLA050056R4100, manufacturer designation Sense7 2M, is a non-contact coded safety magnetic switch designed for monitoring interlocking gates, machine guards and access hatches. Supplied complete with its coded actuator, it provides dependable guard-position monitoring without the mechanical wear associated with conventional tongue-operated interlock switches.
Part of the ABB Sense7 safety sensor series, this model operates from a 24 V DC control supply and provides 2NC + 1NO solid-state outputs. The two fail-safe transistor outputs are complemented by a signalling output, while the integrated LED provides convenient visual status indication during operation and diagnostics.
The 2TLA050056R4100 features a durable plastic housing with an IP67 protection rating and is supplied with a permanently connected 2 m, 8-lead cable. Its compact 88 × 50 × 13 mm dimensions make it suitable for integration into a wide range of industrial guarding systems where reliable non-contact safety sensing is required.

Non-contact safety switches such as the ABB Sense7 monitor the position of movable machine guards without requiring direct mechanical engagement between the switch and actuator. When the coded actuator is correctly positioned near the sensor, the safety outputs provide the appropriate signals to the connected machine safety system.
The Sense7 design is well suited to industrial guarding applications where contamination, vibration or repeated guard operation can make mechanical interlocks less desirable. Its coded magnetic actuation, solid-state outputs, LED indication and IP67 housing provide a practical solution for reliable gate and hatch monitoring in automated machinery.
Typical Applications
- Industrial machine guard monitoring.
- Safety gates and hinged access doors.
- Machine access hatches and covers.
- Packaging and production machinery.
- Conveyor and material handling systems.
- Automated manufacturing equipment.
- Processing machinery and production lines.
- OEM machine building and industrial safety systems.
