Hirose has developed a screwless terminal block series that significantly reduces the electrical wiring time and maintenance workload compared to conventional terminal blocks. The Zero ScrewTM EF2 Series features a single-action connection design that requires the user to simply push a ring terminal into the connector. By eliminating the need for screws, the EF2 Series terminals do not require inspection or retightening to ensure a stable and consistent connection like traditional terminal blocks.

The EF2 Series is available in five different sizes with five different amperage options including 30, 60, 150 250 and 400A.

"The EF2 Series replaces standard terminal blocks that require the user to screw the terminal into the connector, then torque the screw to the proper value. The EF2 Series combines high current capability with quick assembly and reduced maintenance time of up to 40%, while offering a safer alternative to traditional terminal block power solutions," said Bill Kysiak, Product Marketing Manager for Hirose Electric USA.

Simplified installation and maintenance features makes the EF2 Series well suited for hard-to-access applications. It can be used in a wide range of applications including rail, power distribution, machine tools, semiconductor manufacturing equipment and energy storage systems.

The EF2 Series has a rated voltage of 600V AC/DC, a contact resistance of 1Ω, and an operating temperature of -25°C to 105°C.
