SM-1322 Sub-miniature Reed Switch
Form A, Center Contact, Release AT Configurable
All dimensions in mm
This form A reed switch is built with a 2.25 mm diameter glass having a higher wall thickness for better
glass to metal seals, and is a good solution for general purpose, high volume applications with a little shock
and vibration, such as toys. The centre contact also makes it suitable for coil applications. The three
differential ranges available cover a wide range of release specific applications. A specially plated contact
for 230 VAC line voltage switching is also available. This reed switch is Lead (Pb) free and RoHS compliant.
