Specifications • 177 Gocator 2000 Family
Digital Outputs
Each Gocator sensor has two optically-isolated outputs. Both outputs are open collector and open
emitter, this allows a variety of power sources to be connected and a variety of signal configurations.
Out_1 (Collector – Pin N and Emitter – Pin O) and Out_2 (Collector – Pin S and Emitter Pin T) are
independent and therefore V+ and GND are not required to be the same.

The resistors shown above are calculated by R = (V+) / 2.5mA.
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-. The resistor selection is the same as
what is shown above.
