A new, ultra-small magnetically actuated reed sensor that requires no power and is designed for switching CMOS gates and other low power signal switching devices such as implantable medical pacemakers and insulin pumps is being introduced by MEDER electronic.
MEDER MMS Reed Sensors are magnetically actuated on/off sensors that feature no power draw and measure only 2.8 mm (L) [0.110”] by 2.05 mm (W) [0.080”] by 1.2 mm (H) [0.047″]. Designed for switching low power devices where size is critical, they are available with magnetic sensitivity ranges from 1 to 4 millitesla and are tested to withstand up to 15,000 G’s shock from any direction. Choose from 2 surface mount lead designs in a SPST-NO (Form A) version: lead design 1 (straight cut axial lead), and lead design 2 (Gull Wing).
Manufactured using semiconductor wafer technology, MEDER MMS Reed Sensors are supplied in tape and reel according to IEC 286/part 3, suitable for auto pick and place equipment. These SPST reed sensors have a switching voltage of 3 VDC max., with 109 insulation resistance across the contacts. These reed sensors are EDS sensitive and RoHS compliant. Available today at Digi-Key Corporation.
