Series Features
ORT551-1 Series Reed Switch
Series DescriptionThe 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.
- SPDT (Form C) contact configuration for dual-circuit switching
- Compact 14.0 mm glass body for space-constrained designs
- Dog-leg bend on N.C. lead for easy identification and mounting precision
- Hermetically sealed contacts in inert gas for enhanced durability
- Magnetically actuated with no external power required
- Fast switching response for real-time control in low-voltage systems
