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 Telecommunication applications Automotive applications PAD LAYOUT All dimensions in mm [inch] unspecified tolerances +/- 0.1 mm 2.00 1.5017.00 Lead design 1 2.00 1.5020.50 Lead design 4 Reed Sensors for SMD Mounting Lead design 2 2.00 1.5017.00
