Relays with B, D mounting styles and terminal type 4 are compatible with socket SF300CE40E.
Isolation spacer pads for PCB mounting available on request.
For other mounting styles or terminal types, please contact factory.
Non-overlapping arrangement insures that if one of the NO or NC contacts is accidentally welded, none
of the other contacts can be transfered to another state.

Application notes
N°001
CORRECTION DUE TO COIL COPPER WIRE RESISTANCE
CHANGE IN TEMPERATURE
Example: Coil resistance at 25°C: 935 ohms. What is it at 125°C?
Correction coefficient on diagram is: 1.39 at 125°C. R becomes: 935x1.39=1299 Ohms
Correction also applies to operating voltages
