MEDER electronic
MK22 Series
Reed Sensors for
SMD Mounting
DESCRIPTION
MK22-Sensors are magnetically operated, over
moulded Reed proximity Switches for SMD
mounting.
Lead design 1:
Flat, straight leads for PCB slot
mounting.
Lead design 2:
Flat, bent SMD leads (15.6 mm
length)
Lead design 3:
Flat, bent SMD leads (19.5 mm
length)
Magnet force and position magnet/sensor
determine Pull-In and Drop-Out point. The sensors
are supplied taped & reeled according to IEC 286/
part 3 suitable for auto-placement.
FEATURES
•
Over moulded Reed switches for better mechani-
cal resistance
•
Flat leads in three different designs
•
Tape & Reel package
•
Six operate sensitivities available
•
No external power required for sensor operation
APPLICATIONS
•
Electronic PCB`s where all components are
surface mounted
•
No power-requirement sensor for low power
applications
•
Telecommunication applications
•
Automotive applications
All dimensions in mm [inch]
unspecified tolerances +/- 0.1 mm
