ORT551 Series Reed Switch


The ORT551 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 offers reliable switching under 30 VDC with a rated power of 3 W and a switching current of 0.2 A.
This switch is hermetically sealed in inert gas to ensure long-term contact reliability and consistent performance. Its compact form factor and dual-contact configuration make it ideal for applications requiring precise state detection, redundancy, or dual-path control in low-voltage environments.
