XS12JK-4P/Y Speed Sensor Description 1. Overview:< br />     This sensor adopts the principle of electromagnetic induction to achieve speed measurement. It has the characteristics of large output signal, no need for amplification, good performance, no need for external power supply, and can be used in harsh environments such as smoke, oil and gas, water and gas& II. XS12JK-4P/Y Speed Sensor Technical Data:< br />    1、 Output voltage:; When the gear module is 4, teeth are 60, material is g3, and clearance is 1mm< Br/>&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp; 1000 RPM& Gt; 5V (value) < Br/>&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp; 2000 RPM&nbp& Gt; 10V (value) < Br/>3000 RPM& Gt; 15V (value) < br />    2、 DC resistance:; 130Ω～ 140Ω (If the user needs to indicate the resistance value data when placing an order) < br />    3、 Insulation impedance:; At 500V DC> 50MΩ& nbsp;
    4、 Working temperature:- 20℃～l20℃ < br />    5、 Re  Quantity:; About 150 grams (excluding tail wires)< III. Working principle:< br />     When using, a gear should be installed on the shaft where the measured speed is measured (either a spur gear, a helical gear, or a slotted disc can be used). The sensor should be installed on the bracket and the gap between the sensor and the top of the gear should be adjusted to about 1mm& nbsp;
     When the shaft rotates, it drives the gear to rotate. According to the principle of electromagnetic induction, a pulse signal is generated at both ends of the internal coil of the sensor. When the shaft rotates one revolution, Z voltage pulse signals are generated. According to the following formula:< br />                   F＝(n/60)× In the formula, F is the frequency&     Hz/s < Br/>&nbp;&nbp;&nbp;&nbp;&nbp;&nbp; n is the measured shaft speed&nbp& nbsp;  RPM< Br/>Z is the number of gear teeth< br />     When the number of teeth in the gear is 60, the speed n of each minute of the shaft is converted into a voltage pulse signal with a frequency of F. This signal is sent to the SZC/MCS/CSY series intelligent tachometer to reflect the speed of the shaft. nine hundred
