| MEDER electronic DESCRIPTION MK24 are the smallest, 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 in 16mm Tape & Reel package according to IEC 286/part 3 suitable for auto-placement. MK24 Series Reed Sensors for SMD Mounting FEATURES * * * * * Small dimensions: 5.0 x 2.2 x 1.7mm Three operate sensitivities available Tape and Reel available Excellent for low power operations No external power required for sensor operation * UL approved APPLICATIONS * Electronic PCB's where all components are surface mounted * Telecommunication applications (Hook switch in mobile and hard-wired phones) * Switching element in microphones * Medical technologies * Rotary encoder All dimensions in mm [inch] DIMENSIONS LEAD DESIGN 1 1.7 [0.059] 5.0 [0.181] 1.7 [0.059] 2.2 [0.079] LEAD DESIGN 2 1.7 [0.059] 5.0 [0.181] 2.2 [0.079] LEAD DESIGN 3 5.0 [0.181] 2.2 [0.079] 7.7 [0.303] 0.75 [0.03] 7.5 [0.3] 0.75 [0.03] Recommended Pad Layout 2.0 8.7 [0.342] 5.7 [0.224] www.meder.com 285 1.4 [0.055] 1.5 [0.059] 0.75 [0.03] 5.1 [0.201] MK24 Series Reed Sensors for SMD Mounting MEDER electronic ORDER INFORMATION Series MK24 Options Magnetic Sensitivity XA, B, C Lead Design X 1, 2, 3 Part Number Example MK24 - B - 1 B is the magnetic sensitivity 1 is the lead design MAGNETIC SENSITIVITY Sensitivity class Pull In AT Range A B C 5 - 10 10 - 15 15- 20 TAPE & REEL www.meder.com 286 MEDER electronic MK24 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 www.meder.com 287 MK24 Series Reed Sensors for SMD Mounting MEDER electronic CONTACT DATA All Data at 20 C Contact Ratings Switching Power Switching Voltage Switching Current Carry Current Static Contact Resistance Dynamic Contact Resistance Insulation Resistance across Contacts Breakdown Voltage across Contact Operate Time incl.
