4.
5.
Relays with B, D mounting styles and terminal type 4 are compatible with socket SF400CE40E.
Relays with H mounting style are compatible with socket SF400-1F.
Isolation spacer pads for PCB mounting available on request.
For other mounting styles or terminal types or coding, 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.
6.
For "H" mount relays with coil suppression, customer should specify the code.
Double break-double make contacts A and B do not appear in this chart, they are typically high level.

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
