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 I,
Division 2 and Zone 2 hazardous areas
Brad Ultra-Lock (M12) EX 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 operatorindependent 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, therefore, suitable for use in a hazardous Class I,
Division 2 and Zone 2 classified areas.
