Life Test Data Handling & Assembly Instructions *Load increase reduces life expectancy of Reed Switches Use proper lead clamping or heat sinking techniques to prevent mechanical and/or heat stress to the glass seal during bending, cutting, soldering, and welding Mechanical shock as the result of dropping the reed switch typically from a distance of greater than 12 may change its magnetic sensitivity and/or destroy the switch Any form of modification to the switch leads will alter its magnetic sensitivity Series resistor recommended for >5m cable length Glossary Contact Form NO = Normally Open Contacts Form A SPST = Single Pole Single Throw NC = Normally Closed Contacts Form B SPST = Single Pole Single Throw Changeover Form C SPDT = Single Pole Double Throw USA: +1.866.782.6339 salesusa standexmeder.com Version 01 Europe: +49.7731.8399.0 info standexmeder.com 27.01.2015 Asia: +86.21.37820625 salesasia standexmeder.com Modifications in the sense of technical progress are reserved.
