The resistors shown above are calculated by R = (V+) / 2.5 mA.
The size of the resistors is determined by power = (V+)^2 / R.
Inverting Outputs
To invert an output, connect a resistor between ground and Out_1- or Out_2- and connect Out_1+ or
Out_2+ to the supply voltage. Take the output at Out_1- or Out_2-. For resistor selection, see above.
Digital Input
Every Gocator sensor has a single optically isolated input. To use this input without an external resistor,
supply 3.3 - 24 V to the positive pin and GND to the negative.
Active High
If the supplied voltage is greater than 24 V, connect an external resistor in series to the positive.The
resistor value should be R = [(Vin-1.2V)/10mA]-680.
