sold under the ZF brand.

Note: An external pull-up resistor is required, the value of which is dependent on the supply voltage. The resistor should be

connected between the output and Vcc. Refer to the wiring diagram for lead colors or pin numbering as applicable.

Installation

For best results, we recommend targets made from low carbon cold rolled

steel. Other factors that influence sensor performance include gear tooth

height and width, space between the teeth, shape of the teeth and thickness

of the target. As a general guideline, consider a target with minimum

parameters as shown below. Note that smaller dimensions may work, but

testing for the application is required.
