Electrical Diagram


VCC is the 0  5 VDC power supply positive and negative; GND is the ground

Aout is the analog output, Dout is the level output

On the PCB, Indicator light on: Dout is low level. Indicator light off: Dout is high level

The 1k resistor shown on the PCBA is the load resistance (RL), it can be changed by user.

Mounting Diagram

Mount the PCBA to the enclosure with screws. Hole diameter 3mm, pitch distances as per the diagrams given below.
