ABB sense7zm12 Safety Magnetic Switch, 2NC/1NO

Why Choose the ABB Sense7Z M12 Safety Magnetic Switch?

The ABB Sense7Z M12 2TLA050056R2120 is a robust coded non-contact safety magnetic switch designed for monitoring machine guards, gates, hatches and other movable protective devices. Part of the ABB Jokab Safety Sense7 series, it combines non-contact operation with a durable stainless steel construction for reliable guard monitoring in demanding industrial environments.

This Sense7Z variant provides 2NC safety outputs and 1NO auxiliary output, with the safety circuits closed when the guard is closed and the coded actuator is present. Operating from a 24 V DC supply, the switch uses solid-state electronic outputs and includes an integral LED indicator to assist with installation, status monitoring and fault finding.

The 2TLA050056R2120 is supplied complete with its stainless steel actuator and features a 250 mm cable with an 8-pole M12 male connector. Its 316 stainless steel housing, IP67/IP69K enclosure protection and operating temperature range of -25 to +105 °C make it particularly suitable for harsh environments and machinery where frequent cleaning or elevated temperatures may be encountered.

Reliable Stainless Steel Guard Monitoring for Demanding Machinery

Non-contact safety switches such as the ABB Sense7Z M12 monitor the position of movable machine guards without requiring the mechanical engagement associated with traditional tongue-operated interlocks. The sensor is mounted to the fixed machine structure and its coded actuator to the movable guard. When the actuator is within the specified operating distance, the switch provides the appropriate safety and auxiliary output states to the connected safety control system.

The Sense7Z is engineered for demanding applications where environmental resistance and durability are important. Its 316 stainless steel housing, coded magnetic sensing, high ingress protection and wide operating temperature range make it particularly useful for production machinery, processing equipment and applications subject to cleaning procedures, while non-contact operation helps minimise mechanical wear over repeated guard cycles.
