MC-1425 Miniature Close Differential Reed Switch

Very low hysteresis / close differential operation

Glass sealed on round portion of wire for high seal strength

Flattened leads oriented to contact

RoHS Compliant and Lead-free

10-40 operate AT band

This form A reed switch is built with specially pressed blades with slightly higher rigidity for close differential, low hysteresis applications where an operate and release is required with minimum magnet travel, or minimum change in coil voltage. It also uses a glass tube with a higher wall thickness and is very robust. This reed switch is completely Lead-free and conforms to the RoHS directive.
