The ST-series of connectors in Belden's range of Hirschmann™ products celebrates its 40th birthday

Guaranteeing a reliable power supply over four decades



Since 1971, well over a hundred million of Hirschmann™’s ST-series connectors have been produced. Still retaining practically the same original design, these connectors are used to provide power for electric awnings, blinds and shutters. The maximum rated voltage is AC 400 V/DC 250 V, with a rated current of up to AC 16 A/DC 10 A. Because the connectors are reliable, easy to install and have a long operational life they have become the standard for a wide range of applications including mechanical engineering, lighting technology and the medical sectors. This is why the ST-series remains an important part of the connector program and will continue to be further developed if necessary.

The ST-series includes cable plugs and panel-mounted connectors together with their respective sockets. Four connector versions with different numbers of poles are available (2+PE, 3+PE, 4+PE, 5+PE). The connectors are offered in molded cable or field-attachable versions. Customer-specific variants can also be supplied on request.

The field-attachable versions are suitable for cross-section diameters of up to 1.5 mm. They can be attached rapidly and securely using screw or crimp terminals without the need for any special tools. Strain relief is provided by a PG11 cable gland and an interior cable clamp.

The compact connector housing is made of polyamide and therefore resistant to lubricants, ozone and UV radiation. All versions comply with IP54 protection class requirements, have both VDE and UL approvals, and are designed for a temperature range of -30 to +90°C. A safety bracket ensures a reliable connection even in the case of strong vibrations.

The outstanding quality of Hirschmann™ ST- connectors has assured them a place in history. In the words of product manager Hartmut Unverricht: “These power connectors have proven their reliability time and time again over the last 40 years in both indoor and outdoor applications. The ST-series offers the optimum solution for just about any possible scenario. It's an example of where "fit and forget" truly applies.”
