Littelfuse Reed Switch

UL, ATEX Class I, Zone 2. MDSR-7 Subminiature 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. They 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 12.7 x 1.8 mm and house Form A (SPST normally open) contacts. Item 905-8929 has an AT 10-15 sensitivity rating. Item 905-8922 has an AT 10-25 sensitivity rating. Item 905-8926 has an AT 15-20 sensitivity rating. Potential Applications. Reed Relays (particularly suited to ATE type applications) Security Systems Limit Switching Office Equipment. Features. Sub-miniature normally open switch Capable of switching 200V or 0.5A at up to 10W Available sensitivity range 10-25 AT Operating temperature range: -40°C to +125°C
