Series Features
MK33-66 Series Surface Mount Reed Switch
Series DescriptionThe MK33-66 Series is an ultra-miniature, automotive-grade SPST-NO (Form A) reed switch designed for surface mount applications. Engineered with a unique barrel lead design, it offers enhanced stability, coplanarity, and solderability—making it ideal for high-volume, automated PCB assembly
With a glass body length of 14 mm and diameter of 2.2 mm, the MK33-66 delivers reliable switching performance in a compact footprint. Its low-profile construction and self-aligning leads allow for precise placement in tight PCB layouts, including ladder arrays for multi-point sensing. The switch is capable of handling up to 200 VDC, 0.5 A, and 10 W, and is supplied in Tape & Reel packaging per IEC 60286-3 standards.
