MEDER electronic
MK23 Series
Open Reed Sensors
for SMD Mounting
MK23-35
MK23-80
MK23-66
MK23-46
DESCRIPTION
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
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.
APPLICATIONS
• Electronic PCB`s where all components are
surface mounted
• No power-requirement sensor for low power
applications
• Telecommunication applications
• Automotive applications
DIMENSIONS
All dimensions in mm [inch] unspecified tolerances +/- 0.1 mm
