ORT551-1 Series Reed Switch

The ORT551-1 Series is a miniature SPDT (Form C) reed switch designed for changeover-type operation in compact electronic systems. With a glass body length of 14.0 mm and a diameter of 2.54 mm, it delivers reliable switching under 30 VDC with a rated power of 3 W and a switching current of 0.2 A.

This reed switch features a unique mechanical detail: the normally closed (N.C.) lead includes a dog-leg bend, aiding in identification and mounting alignment. Its hermetically sealed contacts are enclosed in inert gas, ensuring long-term reliability and consistent performance in both consumer and industrial environments.
