MDRR-DT Subminiature Axial Lead Reed Switch, Low Power

These subminiature, axial lead reed switches can switch 125 V dc at 5 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 Form C (SPDT change over) contacts.
