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. 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 12.5 x 2.1 x 2.1mm and the simple internal structure. • Electronic PCB’s where all components are surface mounted • Excellent for low power operations • No external power required for sensor operation • Telecommunication applications Hook switch in mobile and hard-wired phones • Switching element in microphones FEATURES • Two operate sensitivities available • Tape and Reel available • J Lead available DIMENSIONS All dimensions in mm [inches] 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.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK17 Series Meder Electronic Reed Sensors for SMD Mounting TAPE & REEL (LEAD DESIGN 1 & 2) TAPE & REEL (LEAD DESIGN 3) www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 Meder Electronic MK17 Series Reed Sensors for SMD Mounting SOLDERING INFORMATION TRAY (J-LEAD OPTION ONLY) www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK17 Series Meder Electronic Reed Sensors for SMD Mounting CONTACT DATA All data at 20 0 C Contact Form --> Contact Ratings Conditions Form A Min.
