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.
FEATURES
Lead design 2: Flat, bent SMD leads (15.6 mm
length)
Lead design 3: Flat, bent SMD leads (19.5 mm
length)
• 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
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.
APPLICATIONS
• Electronic PCB`s where all components are
surface mounted
• No power-requirement sensor for low power
applications
• Telecommunication applications
• Automotive applications
