The EM12M Series Power Connector is a welcome addition to the Hirose Electric family of power
connectors. A single-position connector, the EM12M features easy snap-in locking with an auditory
click, and can handle up to 90 Amps. This series is designed with multiple contact points that generate
high reliability, high current carrying capacity and low resistance. It also features finger protection to
prevent accidental electric shock to operators.
Cables are attached using industry-standard ring terminals and crimp tools, which simplifies assembly.
In addition, mating keys and colored housings are provided to prevent mis-mating.
Operating temperature is -25°C to +105°C, with a rated voltage of 600V AC/DC, contact resistance of
0.5mΩ Max. (DC 1 Amp) and it is rated for 30 mating cycles.
Applications for the EM12M Series include industrial storage batteries, uninterrupted power supplies,
medical equipment, power inverters, robotic controllers and base station transceivers.

HIROSE LAUNCHES HIGH POWER
WIRE-TO-WIRE CONNECTOR SYSTEM THAT SUPPORTS 90 AMPS
SIMI VALLEY, CA — April 8, 2015 — Hirose, a leader in the development of innovative
connector solutions, has designed a new high power wire-to-wire connector system for industrial
and medical applications. The EM12M Series single position, snap-in lock power connector
supports up to 90 Amps using 22mm2 cables. A reliable, multi-point contact design delivers low
contact resistance and high current carrying capacity.
The EM12M Series utilizes mating keys and colored housings to prevent mis-wiring in installations
with multiple wire-to-wire connectors. Providing additional safety measures, the EM12M Series
meets the IEC 60601 finger test to protect field operators from electrical shock.
The EM12M Series features a quick and secure snap-in inertia lock, with an audible click and tactile
snap that indicates complete mating. The high power wire-to-wire connector system simplifies
assembly, as the receptacle accepts a standard crimp terminal on the receptacle for 38mm2, 22mm2
and 14mm2 wire sizes. The receptacle also accepts a BUS bar connection. The plug can be crimpterminated with a standard crimp tool.
“With its circular, multi-contact point design, the EM12M Series high power wire-to-wire
connector system minimizes contact resistance to achieve a very high current capability,” said Rick
van Weezel, Vice-President of Sales and Marketing for Hirose Electric USA. “The EM12M Series
connector is one of the highest current-rated wire to wire connectors in the Hirose product family.”
Well suited for a variety of high power applications, the EM12M Series connector systems is
currently being used in power controller inverter, robot controller, storage battery, medical
equipment, Base Station Transceiver, and UPS applications.
The EM12M Series has an operating temperature range of -25˚C to + 105˚C, a contact resistance of
0.5m ohms maximum at 1A, and an insulation resistance of 1000M ohms maximum at 500VDC.
The connector has a rated voltage of 600VAC/DC, rated current up to 90A, and a withstanding
voltage rating of 3310VAC.
The EM12M Series is UL and TÜV certified.
