BE-Series

(formerly known as ECO 842-Series)

All-purpose Reed Relays in various versions

With the extensive BE series you have the choice between a metal and a plastic casing. The globally current pinnings assure the availability of widely pin-compatible Reed Relays. According to the different casings, either 1 to 5 form A switches, 1 to 2 form C switches, 2 form A and 2 form B switches or 1 to 2 bistable (E) form A switches are offered. Special low thermal versions are also available. You can choose between dry and mercury wetted reed switches which allow to switch without bounce at a extremely high life expectancy. The BE series is completely potted with a durable flexibly Polyurethane resin. Versions with an extremely high insulation resistance of 10E14 Ohm achieved through a special epoxy potting compound are also available for special requirements of test systems, medical equipment and precision measuring devices. This series` range of applications is very wide-spread due to the variety of possible contact combinations:

  • Telecommunication
  • Medical equipment
  • Test and measurement
  • General applications
