NOTES
1. Specification values for pick-up and
drop-out voltages are for the relay mount-
ing with its terminals below.
2. When mounting the relays within 1 mm.
.039 inch , please notice the condition be-
low.
1) Mount the rela ys in the same direction.
2) Coil terminals (Terminal No. 1 & 2) po-
larity should be arranged in the same di-
rection.
3) Allowable contact current is 2 A.
4) About the electrical life f or close mount-
ing, please refer to data below.
