Axial Lead Reed Switches Low Power > MITI-3V1 MITI-3V1 7mm Ultra-Miniature Reed Switch RoHS Description The MITI-3V1 ultra-miniature reed switch is a normally open switch with a 7.00mm long x 1.80mm diameter (0.276 x 0.071) glass envelope, which is capable of switching 170Vdc at 10W. It has a high insulation resistance of 10 ohms minimum and low contact resistance of less than 150 milliohms. The MITI-3V1 is also available in a surface mount version, that is, MISM-3V1. Features Ultra-miniature, normally Available sensitivity range 6-10 AT open switch Capable of switching 170Vdc or 0.25A at up to 10W Benefits Agency Approvals Hermetically sealed switch contacts Zero operating power required for are not affected by and have no contact closure effect on their external environment Excellent for switching micro- Agency Agency File Number Ampere-Turns Range Very low space requirement controller logic level loads E47258 6-10 AT E471070 Applications DEMKO 14 ATEX 1393U 6-10 AT Reed relays Metering Security Mobile phones Dimensions Dimensions in mm Switch Type CL OF OVERLAP 23.00 (.906) REF.
