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 MK23-35 Lead Design 1 www.meder.com 278 MK23-87 Lead Design 2 MEDER electronic MK23 Series Open Reed Sensors for SMD Mounting DIMENSIONS All dimensions in mm [inch] unspecified tolerances +/- 0.1 mm MK23-46 Lead Design 2 14.8 [0.582] Lead Design 4 ø 2.0max.
