Meder Electronic MK15 Series 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. APPLICATIONS 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). • Electronic PCB’s where all components are surface mounted • No external power required for sensor operation • 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 DIMENSIONS All dimensions in mm [inches] MAGNETIC SENSITIVITY SENSITIVITY CLASS PULL IN AT RANGE B 10 - 15 C 15 - 20 ORDER INFORMATION Part Number Example D 20 - 25 MK15 - B - 1 E 25 - 30 B is the magnetic sensitivity 1 is the lead design F 30 - 35 G 35 - 40 SERIES MAGNETIC SENSITIVITY LEAD DESIGN MK15 - X - X OPTIONS B, C, D, E, F, G 1, 2 www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK15 Series Meder Electronic Reed Sensors for SMD Mounting TAPE & REEL SOLDERING INFORMATION www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 Meder Electronic MK15 Series Reed Sensors for SMD Mounting CONTACT DATA All data 20 0 C Contact Ratings Contact Form --> Conditions Form A Min.
