MC-1425 Miniature Close-differential Reed Switch

This Form A type MC-1425 Close Differential 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. The cropped of this Close Differential Reed Switch is suitable for smaller plastic housings and can be soldered to cables, the SMD version is suitable for reflow on PCBs, and the vertical and horizontal mount versions are suitable for mounting on through hole PCBs.
