Maximum operational reliability and ease of maintenance in almost any application

Belden’s new Hirschmann™ GDM series of fieldattachable valve connectors offers maximum flexibility due to a wide range of variants.


Our new fieldattachable GDM type B valve connectors, developed in particular for use in mechanical and plant engineering, guarantee both a reliable power supply and secure data communication. These benefits significantly improve the availability of components such as magnetic valves, pressure transducers, temperature sensors and flow monitors, and enable increased productivity of machines and systems.

When it comes to precisely controlling valves, the valve connectors also permit reliable solutions in many industries beyond mechanical and plant engineering. The braking systems on trains or trucks are just one prominent example. Since these valve connectors fulfill all relevant international standards, they can be used anywhere in the world – a major advantage in the age of globalization.

We offer you the GDM valve connectors, which are easier to handle due to the protruding gripping surfaces, either without circuitry or with more than 20 different electronic inserts. For the versions with circuitry, the downstream circuitry is protected against voltage surges and electromagnetic interference. For the versions without circuitry, which are available with and without LEDs in yellow, red or green, five different voltage ranges (12 V, 24 V, 48 V, 120 V or 250 V) are available.

These valve connectors can even withstand extreme stresses caused by the harshest environmental conditions. The connectors are backed by industrial protection class IP65/67 and optionally IP68, as well as a maximum operating temperature range from -55°C to +125°C (standard: -40°C to +125°C for versions without circuitry; -40°C to +90°C for wired variants). High shock and vibration resistance, as well as a high degree of resistance to numerous chemicals and UV light, are standard features.

Depending on the version, the rated voltage ranges from 12 to 250 VAC/VDC, while the rated current is between 1 and 10 A with circuitry, 1 and 16 A without. The bodies of the valve connectors, which have two poles and PE, are made from either black or transparent polyamide (PA). Customer-specific versions are available on request.

Cables with diameters from 4.5 to 10.0 mm and a cross-section of up to 1.5 mm 2 may be connected. Assembly, for which you can also use gaskets from the previous series, simply requires the tightening of the accompanying central screw. To ensure secure connections, Belden field-attachable GDM valve connectors have integrated strain relief compliant with UL 2238.
