Hengstler RDA Safety Relays

Hengstler RDA Safety Relays is a product from Hengstler. This product come from Safety Relays categories. Additional focus was put on low coil power consumption to reduce the heat, emitted by the relay, to a minimum.

To ensure that our relays as used in your applications carry on doing their job reliably for years, the quality of products bearing the HENGSTLER name is the highest priority. All our locations are certified to ISO 9001 and ISO 14001, and the entire product range is, as you would expect, in conformity with RoHS and REACH regulations.

For decades, HENGSTLER has been intensively involved in matters relating to forcibly guided, or captive, contacts and, as a result, with safety relays. Our large, international customer base benefits from this experienced gathered over many years when it comes to developing and manufacturing relays with forcibly guided contacts.
