NOTES
All values at 20°C (68°F).
Relay may pull in with less than “Must Operate” value.
Relay has fixed coil polarity.
For complete isolation between the relay’s magnetic fields, it is recom-
mended that a .197" (5.0 mm) space be provided between adjacent relays.
5. Relay adjustment may be affected if undue pressure is exerted
on relay case.
6. Specifications subject to change without notice.
