Belden Inc. is extendeing its Hirschmann product programme to include new field-attachable valve connectors from the GDM series. These type-B connectors guarantee both a dependable power supply and reliable data transmission, ensuring high productivity for systems and machines. They are available without circuitry or with more than 20 different electronic inserts that protect downstream circuitry against voltage surges or electromagnetic interference. Versions featuring built-in status indicators (with/without circuit protection) are also available.

The valve connectors feature industrial protection class IP65/67 (optionally IP68) and can be used within a maximum temperature range of -55degC to +125degC. Other connector features include high shock and vibration resistance, and extensive resistance to chemicals and UV radiation. Easy-to-grip housings ensure that connectors can be rapidly assembled. Rounded edges make it difficult for dirt to accumulate and ensure that it can be easily removed.

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

Cable diameters of between 4.5 and 10.0mm with a cross-section of up to 1.5mm2 can be used. Connectors can be assembled simply by tightening the accompanying central screw. No additional gasket is required. Integrated strain relief compliant with UL 2238 ensures secure connections.

With the field-attachable Hirschmann valve connectors from the GDM series, Belden offers a variety of models suitable for flexible connectivity in a wide range of industries. As Product Manager Hartmut Unverricht explains: “Mechanical and plant engineering are not the only areas where our connectors bring maximum operational reliability and ease of maintenance. They are also used in the transportation sector, for example, in the braking systems of trains or trucks.”
