Gruner – for 50 years the name has stood worldwide for

Innovative relay, solenoid and actuator technology.

Superior design principles, centuries of experience in co-development, permanent investment in the latest production and QS technologies as well as high vertical integration - all of this has turned Gruner into a reliable and efficient partner for numerous leading companies all over the world.

Consistent Specialization in Energy Management plus

Targeting of the Semiconductor, Automotive and Mechatronic Markets

Have turned Gruner into the world market leader in several sectors.

At our headquarters in Wehingen in Southwest Germany, we develop and manufacture our products on high-quality production lines taking up more than 7000 square meters of production space. For 25 years now, our own assembly plant in Tunis (Tunisia) has been helping to guarantee an advantageous price-performance ratio plus high delivery security.

We offer magnetic latching relays with contact ratings from 8 A up to 200 A. Magnetic latching relays are pulse driven and maintain their switching position after power is turned off. Pulses of reversed polarities are required for the setting and resetting mode. The design of the "H-Armature" is unique for the line of magnetic latching relays. The rotating movement as well as lever forces inside the relay enable to the relay to switch high contact currents (up to 200 Amp.) with diminutive effort. The core of the "H-Armature" is a permanent magnet, which results in vibration and shock resistance. Compared to switches and contactors the size of the magnetic latching relay is typically smaller and the cost is less.

Typical applications are:

• Energy and load management systems
• Lighting control systems (building control as well as street light control)
• Remote disconnect/reconnect solutions for utilities
• Pre-payment meters
