Made in Japan

HAMLIN - MDRR-4-1722 - Reed Switch Glass Capsule, Two Ferromagnetic Nickel-Iron Wires.

The two wires are formed into "reeds" by flattening one end. The reed ends are carefully aligned with a small overlap and then permanently sealed inside the glass capsule. The overlap or contact area of the reeds is coated with special metals such as ruthenium. The nickel-iron leads are tin plated so that they can be soldered.

Benefits:

• Hermetically sealed switch contacts are not affected by and have no effect on their external environment
• Can be used as changeover or normally closed contact
• Zero operating power required for contact closure
• Excellent for switching micro-controller logic level loads

A miniature changeover switch with a 14.73mm long x 2.54mm diameter (0.580" x 0.100") glass envelope. 

The Reed Body Measures 0.580" Long. 0.100" Diameter Length with leads is Approximately 1.60" Long
