4pcs Sensor Module Magnetic Kit Normally Open LM393 Comparator for Easy Installation

Imported normally open The comparator output signals clean, good waveform, driving ability, than 15mA. The output form: digital ing output (0 and 1)

is dry short, is a kind of passive electronic contact has a simple structure, small size and easy to control, etc., the is generally a sealed glass tubes are installed there are two flexible iron panels, also called metal rhodium has a filling of inert gas. Normally, two glass tubes made of special materials s are separated. When a magnetic substance near the glass tube, under the action of magnetic field lines, the two pipe is magnetized and attract each other contacts, the will pull together to make a circuit of the connected node communication. After the disappearance of the external magnetic force, two s separately because of their elasticity, the line also disconnected. Therefore, as a signal to control the use of magnetic field lines ing devices, the can be used as a sensor for counting, spacing, and so on (in the security system is mainly used for door sensor, window magnetic production), but also It is widely used in a variety of communication devices. In practice, usually with a permanent magnet control the two metal sheets turned on or not, it is also known as magnetron. Features: Imported normally open   The comparator output signals clean, good waveform, driving ability, than 15mA.  The output form: digital ing output (0 and 1)  A fixed hole for easy installation  Small PCB board size of 3.2cm x 1.4cm  Using a wide voltage comparator LM393  Application: SPC exchange, copy machine, washing machines, refrigerators, camera, disinfect cupboard, door magnetic, magnetic window, electromagnetic relays, electronic weighing , meter, gas meter, water meter.

Specification: Working voltage of 3.3V-5V  Type:Normally-open Comparator : LM393 Output Type : Digital output (0 and 1) PCB board size: 3.2*1.4cmCelsius1.3*0.6in Weight: Approx.13gCelsius0.5oz Module USES: 1. The dry pipe need magnet, when sensing certain magnetic force, will show ON state, the module output low ; no magnetic, show OFF state, output high , dry pipe and magnetic induction distance within 1.5 cm, this distance ,insensitive or will not trigger ; 2. The module DO output end can connect directly to microcontroller ICelsiusO port, triggered by single chip microcomputer can detect dry pipe status;it can detect the trigger state of the dry by SCM 3. Modules DO output end connect the IN end of relay, can compose high power dry pipe es, control high voltage directly.
