Description:
NVE offers these products specifically for use as sensors for gear tooth wheels or magnetic encoders with a digital output signal. The pulse output from the sensor corresponds with the gear teeth passing in front of it. When a gear tooth or magnetic pole is in front of the sensor, the sensor’s output goes high; when the gear tooth or magnetic pole moves away, the output returns to low. This repeats at every tooth/pole, resulting in a pulse train output that provides speed information from the gear or encoder. Three part numbers are currently available: the AKL001-12 is designed for gear teeth or encoders with a pitch of 2.5 to 6mm, the AKL002-12 for a pitch of 1 to 2.5mm, and the AKL00312 for a pitch of 0.6 to 1.5mm. In order to minimize the number of wires leading to the sensor, the part is configured as a two wire device. The two output states are indicated with a change of current through the part. Therefore, when the part is in the digital low state, current is about 3mA. When the part is in the digital high state, the current increases to ……
