MDSR-10 Low Power Sub-Miniature Reed Switches

Littelfuse MDSR-10 Low Power Sub-Miniature Reed Switches are normally open switches with a 10.16mm long x 1.80mm diameter (0.400” x 0.071”) glass envelope, capable of switching 200VDC at 10W. The switches feature a high insulation resistance of 1012Ω minimum, a low contact resistance of less than 120mΩ, and a wide -40°C to +125°C operating temperature range. The Littelfuse MDSR-10 Low Power Sub-Miniature Reed Switches are ideal for switching microcontroller logic level loads.
