reliability and fully integrated direction, typical products of Philips (Philips) produced KMI15 Series Magnetoresistive speed sensor integration . The sensor is excellent , good security , stability, strength , speed sensor is a discrete ideal upgrade product . KMI15 series including KMI15-1, KMI15-2, KMI15-4 and other models, they work the same way , only a slight difference in performance . Take the following example to introduce KMI15-1 series integrated speed sensor that works with specific application methods . 1 KMI15-1 -type sensor, the KMI15-1 -chip high-performance magnets , magnetic resistance sensor and IC.

It uses IC to complete the signal transformation function , the output current signal proportional to the frequency and the measured speed and current changes in the signal amplitude 7mA ~ 14mA. Because of its relatively simple external circuit , which is easy to measure speed with the secondary instrument . KMI15-1 devices , wide measuring range , high sensitivity, its frequency range of gear rotation is 0 ~ 25kHz, and even in the rotation frequency is close to zero , it can also be measured. Sensor and the maximum magnetic gear distance of 2.9mm ( typical value) , as far apart with the gear , so use safer . Anti-interference ability of the sensor , both directions , it is not sensitive to axial vibration .

In addition, the chip also electromagnetic interference (EMI) filter , voltage controller and current source , thus ensuring the characteristics of its work from external factors. KMI15-1 size smaller , the maximum external dimensions of 8 × 6 × 21mm, can be reliably fixed in the gear around . KMI15 with +12 V power supply (typical) , a maximum of 16V. Register of the operating temperature range -40 ~ +85.
