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.
- SPDT (Form C) contact configuration for flexible changeover switching
- Compact 14.0 mm glass body for space-constrained designs
- Hermetically sealed contacts in inert gas for enhanced durability and reliability
- Straight lead configuration for easy PCB mounting and mechanical stability
- Magnetically actuated with no external power required, ideal for energy-efficient systems
- Rated for 3 W, 30 VDC, and 0.2 A switching current for signal-level applications
