BE Series
All Purpose
Reed Relays
With the extensive BE Series you have the choice
between a metal and a plastic casing. The glob-
ally current pinnings assure the availability of widely
pin-compatible Reed Relays. This series` range of
applications is very wide-spread due to the variety of
possible contact combinations:

* The pull-in / drop-out voltage and coil resistence will change at the rate of 0,4 % per degrees C.
** Reclosure of Form B may occur if the max. voltage is exceeded. Coil polarity on Form B must be observed. Pin 2 is positive.
*** Coil polarity must be observed. Applying a 2 ms pulse to Coil No. 1 with nominal voltage will latch the contacts.
Applying a 2 ms pulse to Coil No. 2 will unlatch the contacts.
**** The gures in brackets are for relays in metal casing.
