MDCG-4 Sub-miniature Axial Lead Reed Switch, Low Power
These subminiature, axial lead reed switches can switch 200 V dc at 10 W. These switches 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. The glass envelope measures 15.24 x 2.28 mm and house normally open contacts.
Item 905-8887 has an AT 12-18 sensitivity rating.
Item 905-8881 has an AT 17-23 sensitivity rating.
