Product Details
MDSM Surface Mount Reed Switch, Low Power
These surface-mount reed switches can switch 200 V dc at 10 W. They have a low electrical footprint and require zero operating power to close the contacts. These units are hermetically sealed and with magnetically operated contacts they are highly resilient to contamination. Even operating in conditions long after optical and other technology reed switches would have failed. They have Form A (SPST normally open) contacts.
Item 905-8900 has a glass envelope measuring 10.16 x 1.8 mm and has an AT 20-25 sensitivity rating.
Item 905-8904 has a glass envelope measuring 15.24 x 2.28 mm and has an AT 12-18 sensitivity rating.
