Ultra Mini High Performace Proximity Sensors
MEDER electronic's MK24 series Reed Sensors achieve a minimum life expectancy of 50 million operations at 5V, 5mA, 100Hz while measuring only 5mm x 1.8mm x 2.2mm. At 50 millions operations, the MK24's base reed switch, a 4mm KSK-1A04 unequivocally surpassed all other reed switches in its size class. The MK24 reed sensor is a hermetically sealed switch in a robust thermoset molded package. This tiny energy saving device requires no external power to operate, cutting down on power consumption costs making them especially well suited for low power applications while reducing space requirements. Sensitivity ranges from 1.5-10mT are available.
