MEDER MK17-C-2

MEDER electronic
MK17 Series
Reed Sensors for
SMD Mounting
DESCRIPTION
MK17 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.
• Lead design 3:
J-Lead.
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 12.5 x 2.1 x 2.1mm and the simple
internal structure.
