Why Choose the ABB Sense7 M12 Safety Magnetic Switch?
The ABB Sense7 M12 2TLA050056R2100 is a coded non-contact safety magnetic switch designed for reliable monitoring of machine guards, gates and access hatches. Part of the ABB Jokab Safety Sense7 series, it uses solid-state sensing technology to detect its coded actuator without requiring mechanical contact, helping reduce wear in frequently operated industrial safety applications.
This Sense7 M12 model provides 2NC failsafe outputs and 1NO auxiliary output, allowing the guard position to be monitored by a suitable safety control system while also providing a signalling output. It operates from a 24 V DC supply and features an integral LED status indicator for convenient visual indication during installation, operation and maintenance.
The sensor is supplied complete with its coded actuator and has a 250 mm cable terminated with an 8-pole M12 male connector for convenient machine wiring. Its compact 88 × 50 × 13 mm polyester housing, recommended 5 mm setting gap and high ingress protection make it well suited to modern automated machinery where dependable non-contact guard monitoring is required.

Non-contact safety sensors such as the ABB Sense7 M12 monitor movable guards without the mechanical engagement required by conventional tongue-operated interlock switches. The sensor is installed on the fixed machine structure and its coded actuator on the movable guard. When the actuator is correctly positioned, the sensor detects it and provides the corresponding safety and auxiliary output states to the connected control system.
The non-contact operating principle helps minimise mechanical wear and allows a degree of installation tolerance, making the Sense7 particularly useful on machine doors and guards that are opened frequently. Its coded actuator, solid-state outputs, LED indication and high ingress protection provide a dependable solution for machine builders requiring robust guard monitoring within modern industrial safety systems.
