MEDER electronic 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. Lead design 2: Flat, bent SMD leads (15.6 mm length) Lead design 3: Flat, bent SMD leads (19.5 mm length) FEATURES • Over moulded Reed switches for better mechanical 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 PAD LAYOUT All dimensions in mm [inch] unspecified tolerances +/- 0.1 mm 2.00 Lead design 4 2.00 17.00 2.00 1.50 1.50 17.00 Lead design 2 20.50 1.50 Lead design 1 www.meder.com 273 MK22 Series MEDER electronic Reed Sensors for SMD Mounting DIMENSIONS All dimensions in mm [inch] unspecified tolerances +/- 0.1 mm Lead design 1 Lead design 2 Lead design 4 www.meder.com 274 MK22 Series MEDER electronic Reed Sensors for SMD Mounting ORDER INFORMATION Part Number Example Series MK22 - B - 4 B is the magnetic sensitivity 4 is the lead design Magnetic Sensitivity Lead Design MK 22 - X- X Options A, B, C 1, 2, 4 MAGNETIC SENSITIVITY Sensitivity Class Pull In AT Range B 10 - 15 C 15 - 20 TAPE & REEL www.meder.com 275 MEDER electronic MK22 Series Reed Sensors for SMD Mounting SOLDERING INFORMATION reflow soldering conditions according JEDEC norm J-STD-020C 40 s 260 oC 183 oC 125 oC Ramp up: max. 6K/s 120 s 120-180 s www.meder.com 276 Ramp down: max. 8/Ks MEDER electronic MK22 Series Reed Sensors for SMD Mounting CONTACT DATA All Data at 20° C Contact Form → Contact Ratings Conditions Form A Min.
