1, the use of imported groove coupler sensor
2, the slot width 5mm.
3, the output status indicator lamp output high, output low lights.
4, block, output high; no shelter, output low.
5, the comparator output signal clean, good waveform, driving ability, than 15mA.
6, the working voltage of 3.3V-5V
7, the output format: digital switching output (0 and 1)
8, a fixed bolt holes for easy installation
9, small plates PCB size: 3.2cm x 1.4cm
10, using a wide voltage comparator LM393
Module for use:
1. module slot unobstructed, receiver tube conduction module DO output low, when blocked, DO output high;
2. DO module can be connected to relays, limit switches and other functional composition, and to be connected with active buzzer module, consisting of alarm.
Widely used in motor speed detection, pulse count, the position limit, etc.
