Low-Height Space-Saving Connector with Proven Combi-Contact

The Hirschmann(TM) GDMF is a new generation of valve connectors with an extremely flat design. This meets the ever growing demand for highly compact rectangular connectors.

With a height of just 26 mm, the rectangular connector in protection class IP 65/67 has a perfect fit in any given application. A captive seal and non-slip surfaces on both sides provide for ease of assembly and disassembly.

The new compact design features the patented combi contact, known from the proven GDM series and laid out for a wide range of cable gauges up to 1.5 mm² with outer diameters from 4.5 to 8 mm (in a UL approved version from 4.0 to 6.7 mm). Further product characteristics of the new GDMF valve connector include ultimate resistance to vibration and jarring. The product is available with or without electronic insert with three or four contacts (2+PE or 3+PE).
