High power, wire-to-wire connector designed for medical applications
A high power, wire-to-wire connector, from Hirose, has been designed for industrial and medical applications. The EM12M circular, single position, snap-in lock power connector supports up to 90A using 22mm2 cables. A multi-point contact design delivers low contact resistance and high current carrying capacity.
Mating keys and coloured housings to prevent mis-wiring in installations with multiple wire-to-wire connectors. The connector meets the IEC 60601 finger test to protect field operators from electrical shock.
A secure snap-in inertia lock, with an audible click and tactile snap indicates complete mating. To simplify assembly, the receptacle accepts a standard crimp terminal on the receptacle for 38, 22 and 14mm2 wire sizes, as well as a bus bar connection. The plug can be crimp- terminated with a standard crimp tool.
The connector systems is currently being used in a variety of high power applications such as power controller inverter, robot controller, storage battery, medical equipment, base station transceiver and UPS applications.
The operating temperature range is -25 to +105°C, contact resistance is 0.5mΩ maximum at 1A and insulation resistance is 1000MΩ maximum at 500VDC. It also has a rated voltage of 600VAC/DC, a rated current up to 90A and a withstanding voltage rating of 3310VAC. The connector is UL and TÜV certified.
