MO-1422 Miniature Off-Centre Contact Reed Switch
This MO-1422 Miniature Off-Centre Contact Form A type Reed Switch is designed for highly sensitive magnet applications when the magnet is being approached from the seal/lead side. Measurements are always taken with the contact overlap portion centered to the length of the test coil, with the width of all blades in a batch of switches, facing one way, for better in-group measurement accuracy. The cropped version of the MO-1422 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.
