MEDER MK17-C-1

MEDER electronic
MK17 Series
Reed Sensors for
SMD Mounting
DESCRIPTION
MK17 are magnetically operated Reed proximity
switches for SMD mounting.
APPLICATIONS
• Electronic PCB’s where all components
are surface mounted
• Telecommunication applications
Hook switch in mobile and hard-wired phones
• Switching element in microphones
• 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.
