NOTES

1. All values at 20°C (68°F).

2. Relay has fixed coil polarity.

3. Relay may pull in with less than “Must Operate” value.

4. Relay adjustment may be affected if undue pressure is exerted

on relay case.

5. For complete isolation between the relay’s magnetic fields, it is

recommended that a .197" (5.0 mm) space be provided between

adjacent relays.

6. Specifications subject to change without notice.
