Brad® Ultra-Lock® (M12) EX Connection System
for Zone 2 Hazardous Locations

Achieve non-arcing connections in a one-step installation process with the Brad® Ultra-Lock® (M12) EX Connection System, designed for industrial automation use in Class 1, Division 2 and Zone 2 hazardous areas.
Brad Ultra-Lock (M12) cordsets and receptacles provide process automation installers a safe, quick connection interface for instrumentation and control devices in potentially explosive and hazardous areas.
The patented push-to-lock technology provides a simple and secure operator-independent connection. Ultra-Lock connectors are designed to eliminate connector-related intermittent signals in the harshest environments.
The Ultra-Lock (M12) EX connector has been designed with an integral isolating ring that limits the access to the release mechanism of the connector. The connector can be pushed on, but requires a screwdriver to disconnect. With this characteristic, the connection point is considered normally non-arcing and, therefor, suitable for use in hazardous Class I, Division 2 and Zone 2 classified areas/
