MK15 Series MEDER electronic Reed Sensors for SMD Mounting DESCRIPTION MK15 are magnetically operated Reed proximity switches for SMD mounting. • • Lead design 1: Flat, straight leads for PCB slot mounting. • • Lead design 2: Flat, bent SMD leads. The sensors are supplied taped & reeled according to IEC 286/part 3 suitable for auto-placement. The special features of this series are the small dimensions of only 19.5 x 2.5 x 2.5mm and the simple internal structure (low-cost version). APPLICATIONS • Electronic PCB’s where all components are surface mounted • Telecommunication applications Hook switch in mobile and hard-wired phones • Switching element in microphones FEATURES • • • • • • Excellent for low power operations High power switches available Six operate sensitivities available Tape and Reel available No external power required for sensor operation UL approved DIMENSIONS All dimensions in mm [inch] ORDER INFORMATION MAGNETIC SENSITIVITY Sensitivity class Pull In AT Range B 10 - 15 C 15 - 20 D 20 - 25 E 25 - 30 F 30 - 35 G 35 - 40 Part Number Example MK15 - B - 1 B is the magnetic sensitivity 1 is the lead design www.meder.com 254 Series Magnetic Sensitivity Lead Design MK15 - x- x Options B, C, D, E, F, G 1.2 MEDER electronic MK15 Series Reed Sensors for SMD Mounting TAPE & REEL 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 Ramp down: max. 8/Ks www.meder.com 255 MEDER electronic MK15 Series Reed Sensors for SMD Mounting CONTACT DATA All Data at 20° C Contact Form → Contact Ratings Conditions Form A Min.
