DESCRIPTION
MK23-Sensors are magnetically operated, open
Reed proximity Switches for SMD mounting.
Lead design 1:
Flat, straight leads for PCB slot
mounting.
Lead design 2:
Flat, bent SMD leads (Gull-wing)
Lead design 4:
Round, bent SMD leads for PCB
slot mounting
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
•
Reed switches without moulding case for
reasonable products
•
Five different switch models
•
Flat or round leads in three different designs
•
Four operate sensitivities available
•
Tape & Reel package
•
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
