Standex-Meder Electronics MK24 Reed Sensors are small, magnetically operated reed proximity switches for SMD mounting and is available in three lead designs: flat, straight leads for PCB slot mounting (flat, bend SMD leads; and J-leads). The sensors are supplied in 16mm Tape & Reel package according to IEC 286/part 3 suitable for auto-placement. Standex-Meder designed the MK24 to be excellent for low power operations (no external power required for sensor operation). Ideal for PCBs where all components are surface mounted, telecommunication applications (hook switch in mobile and hard-wired phones), switching elements in microphones, medical technologies, and rotary encoders.
