Cable glands for industrial applications

In the field of industrial electrical installation, cable glands are an indispensable aid. In this field, RST from Wallenhorst near Osnabrück has established itself as a specialist in the cable gland segment. As an owner-managed company, we are now active on an international level and have expanded our business to more than 46 countries. We offer our customers a well-assorted product range in the field of cable glands and accessories.

Cable glands with flexible thread selection

Cable glands are an ideal solution for safely inserting cables and wires - with or without shielding - into electronic housings and for protecting electronic components inside these usually highly sealed housings from damage or undesirable external influences such as dust or moisture. For this reason, we offer a wide range of different cable glands. In order to ensure the most stable connection possible between cables or conductors and enclosures, such as those of an electrical control cabinet, you will find cable glands with different thread types in our product selection:

  • Metric thread, EN 60423
  • PG thread, DIN 40430
  • NPT thread, ANSI B1.20.1

The metric thread - also M-thread - according to EN 60423 is the most common and most sold thread in Europe. Cable glands with armoured conduit thread or PG cable glands are still manufactured, but are increasingly being replaced by metric glands. The third variant is the NPT thread, which is widely used on the American market. The NPT thread is characterized by the fact that it is self-sealing and thus the use of additional sealants can be dispensed with.

Cable glands made of different materials

Different materials are used for RST cable glands, depending on the requirements and the application:

  • Cable gland made of polyamide
  • Cable gland made of brass (nickel-plated)
  • Cable gland made of stainless steel

Depending on the purpose and stress, it makes sense to use a cable gland made of plastic or a cable gland made of metal. A cable gland made of brass is preferably used in connection with electromagnetic compatibility.
