Meder MK15-B-1 Reed sensors for smd mounting Datasheet

MK15 Series
MEDER electronic
Reed Sensors for
SMD Mounting
DESCRIPTION
MK15 are magnetically operated Reed proximity
switches for SMD mounting.
• • Lead design 1: Flat, straight leads for PCB slot
mounting.
• • Lead design 2: Flat, bent SMD leads.
The sensors are supplied taped & reeled according
to IEC 286/part 3 suitable for auto-placement. The
special features of this series are the small dimensions
of only 19.5 x 2.5 x 2.5mm and the simple internal
structure (low-cost version).
APPLICATIONS
• Electronic PCB’s where all components are
surface mounted
• Telecommunication applications Hook switch in
mobile and hard-wired phones
• Switching element in microphones
