Meder MK16-B-1 Reed sensors for smd mounting Datasheet

MEDER electronic
MK16 Series
Reed Sensors for
SMD Mounting
DESCRIPTION
MK16 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 15.6 x 2.3 x 2.3 mm 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
