MK33-87 Series Surface Mount Reed Switch
The MK33-87 Series is an ultra-miniature, low-profile SPST-NO (Form A) reed switch designed for surface mount applications. With a glass body length of 10 mm and diameter of 2.0 mm, it is ideal for compact PCB layouts and high-density sensor arrays.
Engineered with a unique barrel lead design, the MK33-87 offers enhanced coplanarity, solderability, and self-alignment for efficient pick-and-place assembly. Capable of switching up to 200 VDC, 0.4 A, and 10 W, this bare glass reed switch is optimized for tight ladder arrays and continuous liquid level monitoring. Supplied in Tape & Reel packaging per IEC 60286-3 standards.
