The DS series Miniature Relay with highly sensitive and 1500V FCC surge breakdown voltage. The epoxy resin seals the parts and cut off the external atmosphere thus enabling use in difficult environments. Highly stable gold cladding on the contacts ensures that contact resistance changes little over time. Furthermore, the use of twin contacts, a configuration that performs with superior contact reliability, ensures extremely low contact failure rates even under low level loads. High-performance polarized magnetic circuits that utilize the energy of permanent magnets have made it possible to create relays with strong resistance to shock and vibration. In addition to single side stable types, you can take advantage of the memory of functions of convenient 1 coil or 2 coil latching relays.
