Hengstler ROS Safety Relays is a product from Hengstler. This product comes from safety relay categories. Due to the constant high number of electrical switching cycles, the new H-480 can be used for a broad range of safety applications.
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.
