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 6 mm, the AKL002-12 for a pitch of 1 to 2.5 mm, and the AKL003-12
for a pitch of 0.6 to 1.5 mm.
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 3 mA. When the part is in the digital high state, the
current increases to about 10 mA. If necessary, the two-wire output of the AKL-Series parts can be
easily converted to a three-wire current sinking output with the circuit shown in the GT Sensor
applications section.
The parts are rated for the full automotive and industrial temperature range, -40°C to +150°C. They
feature reverse battery protection and have an operational voltage range of 4.5V to 36V. They operate
from DC to 10 kHz. The parts are available in low-profile, surface mount TDFN SO8 packages.
