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. The BE series is completely potted with a durable flexibly Polyurethane resin. Versions with an extremely high insulation resistance of 1014 Ohm achieved through a special PU 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:

The SIL-xK can get separate voltage up to 4kVDV. 
Compared with typical High Voltage Relays the SIL-xK reduce the required space multiple on a PCB.

High voltage relay having up to 10 kVDC switching and 15 kVDC breakdown voltage contact to coil. Reliable switching of high voltages up to 10000 V. The special open construction provides very high insulation values up to 15000 VDC and 1000 Gigaohm between coil and contact. A breakdown voltage of up to 15000 Volt over the open switch is achieved through the use of vacuum reed switches.
