Hengstler Safety Relays H-473

Hengstler Safety Relays H-473

Hengstler Safety relays H-473, HENGSTLER provides a solution for all those applications that require high component density. The max. height of 15.7 mm enables them to be used in 22.5 mm module housings, for example.

The well-designed layout of the relay pins means there is plenty of space at the rear of the circuit board for SMD components. H-473 safety relays conform to EN 50205 standard, Application type A, and IEC EN 61810-1. In addition, these safety relays also meet the requirements for railway signal relays in accordance with UIC 736e.

To ensure that the 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.
