MEDER electronic MK17 Series Reed Sensors for SMD Mounting DESCRIPTION MK17 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. • Lead design 3: J-Lead. 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 12.5 x 2.1 x 2.1mm and the simple internal structure. FEATURES • • • • APPLICATIONS • Electronic PCB’s where all components are surface mounted • Telecommunication applications Hook switch in mobile and hard-wired phones • Switching element in microphones Two operate sensitivities available Tape and Reel available Excellent for low power operations No external power required for sensor operation DIMENSIONS All dimensions in mm [inches] Recommended Pad Layout ORDER INFORMATION SENSITIVITY CLASS PULL IN AT RANGE B 10 - 15 C 15 - 20 Part Number Example SERIES MAGNETIC SENSITIVITY LEAD DESIGN MK17 - X - X OPTIONS B, C 1, 2 MK17 - B - 1 B is the magnetic sensitivity 1 is the lead design www.meder.com Germany # ++49-(0)7733-94870, USA # 800-870-5385 213 MK17 Series MEDER electronic Reed Sensors for SMD Mounting TAPE & REEL (LEAD DESIGN 1 AND 2) TAPE & REEL (LEAD DESIGN 3) www.meder.com 214 Germany # ++49-(0)7733-94870, USA # 800-870-5385 MEDER electronic MK17 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 Ramp down: max. 8/Ks TRAY (j-lEAD opTION oNLY) 215 www.meder.com Europe # ++49-(0)7733-94870, USA # 800-870-5385 MK17 Series MEDER electronic Reed Sensors for SMD Mounting CONTACT DATA All data at 20 0C Contact For m --> Contact Ratings Conditions For m A Min.
