ORD221 Series Reed Switch


The ORD221 Series is a miniature, normally open reed switch designed for medium-load switching applications. With a glass body length of 13.0 mm and diameter of 2.3 mm, it offers a compact footprint suitable for space-constrained designs while maintaining reliable performance.
Rated for up to 10 W, 100 VDC, and 0.3 A, the ORD221 is hermetically sealed in inert gas to ensure long-term contact stability. Its offset lead design supports flexible mounting options, and its pull-in range of 10–30 AT allows for adaptable magnetic sensitivity across various applications.
This series is ideal for general-purpose switching in consumer electronics, automotive systems, and industrial devices where compact size and dependable operation are essential.
