Reed Switches (Package of 100)

Description

These Normally Open DYAD dry reed switches are ideally suited for magnetically initiated switching applications. Super for use as interlocks and alarm transducers. Absolutely unbeatable for monitoring windows, doors and gates in conjunction with a wireless or hardwired alarm system and great for hidden embedded applications. Though thought of as a magnetic device, the switches lend themselves to hundreds of other applications and are simply fun to work with. These switches have sputtered ruthenium contacts and an extraordinary seal strength, achieved by a patented laser sealing of the glass. With conventional axial-lead designs, the result of stresses induced by bending may be seen at the inner end of the switch leads. Such stresses can adversely affect the hermetic sealing characteristics of the glass body or the predefined gap between the switch contacts causing erratic or inadequate performance of the reed switch. The rugged surface mount design of these switches not only eliminates these problems but thermal problems due to excessive heat generated in the soldering process as well. In low level or dry switching environments, switches typically provide >1 billion operations. Max switching Voltage- 200 Volts Switching Current .5 amps Carry Current 1.5 amps Switching Frequency 500 hz Contact Resistance 150 mOhms.
