Add capcitor Cn as shown, close to the sensor , for transient suppression if required. 2. Add pull-up resistor Rpu as shown for sinking output. The Rpu value should be calculated using your supply voltage while keeping the ON state current at a level below the maximum. Rpu = VDD/Io; Rpu = 12Vdc/10mA = 1.2kOhm © 2015 Littelfuse Revised: 11/02/15 littelfuse.com Specifications are subject to change without notice.
