MEDER electronic MK16 Series Reed Sensors for SMD Mounting DESCRIPTION MK16 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 15.6 x 2.3 x 2.3 mm 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 • • • • • Four operate sensitivities available Tape and Reel available Excellent for low power operations No external power required for sensor operation UL approved DIMENSIONS All dimensions in mm [inches] Recommended Pad Layout ORDER INFORMATION Series Magnetic Sensitivity Lead Design MK16 - X- X Options B, C, D, E 1.2 Part Number Example MK16 - B - 1 B is the magnetic sensitivity 1 is the lead design Sensitivity class Pull In At Range B 10 - 15 C 15 - 20 D 20 - 25 E 25 - 30 www.meder.com 245 MEDER electronic MK16 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 www.meder.com 246 Ramp down: max. 8/Ks MK16 Series MEDER electronic Reed Sensors for SMD Mounting CONTACT DATA All Data at 20° C Contact Form → Contact Ratings Conditions Form A Min.
