HDSS half crystal can
relay BS9151 F0026
Resonance free contact system for extreme
environments
Fast operation
Th e HDS5 half crystal can size , 2 pole changeover relay has been in UK production longer than any other comparable relay. Its all welded construction
dynamically balanced armature , fus ion welded seal and special resonance free
contact system ensure satisfactory performance under extreme environmental conditions. The fini shed relay is contaminant free , assured by ultrasonic
cleaning , vacuum de-gassing , sealing into a sta inless steel can by fusion welding
and filling of the relay enclosure with inert dry nitrogen .
op
y
Special relays are available with coil transient suppression incorporated by
the fitting of diodes. In this case polarity has to be observed when connecting
the relay into circuit and this is indicated by the reference HDP6. As a result of
incorporating diodes in this way release time, weight and overall height are
slightly increased.
