MO-1422 Off-centre contact Miniature Reed Switch

Off centre contact blades for precision magnet applications

Round glass and wire for maximum seal strength

RoHS Compliant and Lead-free

15-50 operate AT band

This off centre contact form A reed switch is designed for highly sensitive magnet applications. 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. This reed switch is completely Lead-free and conforms to the RoHS directive.
