High Quality Precision Speed Sensor

Product Description The SM39 series speed sensor is one kind of advanced speed sensors, uses in the non- contact to examine the rotate speed, by the OC gate way output square-wave signal, can connect to the TTL, CMOS and the logic circuit by draught the resistance. Then, can compose the tachometric survey and the control system.The product uses the standard circular pipe waterproofing structure, has the waterproofing, dustproof, guards against the ongreasy dirt, also, It can be reliable worked in the adverse circumstance, is suitable to the domain and industry automation control.Principle of workThe SM39 series speed sensor has used the advanced examination technology, may distinguish has transferred the examination surface each addendum and the tooth valley, transforms for the corresponding speed cyclical square-wave.Technical performance1. Basic performanceFixed examination distance:≤3mmMeasures the fast scope:10 circle of/minutes (every time transfer a gear) ~ 20,000 circle of/minutes     (every time to transfer 60 gear)Output wave shape:Square-waveOccupies the spatial ratio:0.5±0.2Protection function:Is equipped with the power source to tie hands behind the back the protection and the output short-circuits the protection Operating temperature:Conventional product - 40 ~ + 85 ºC, if has the special request please to have custom-made, the maximum temperature may reach 150 ºC2.

In 1995, the first batch of High-tech enterprises were recognized as national state-level. The SUNMOON also passed the certification of ISO 9001 Quality Management System,ISO14001 Environmental Management System and OHSAS 18001 Occupational Health and Safety Assessment Series. With SM series of products measuring instruments manufacturing license qualification and a variety of explosion- proof measurement and control products production qualification,mechanical and electrical equipment installation engineering professional contracting qualification. With independent intellectual property rights of the patented technology189terms. These is the SUNMOON's core competitiveness of the technology.The subject positioning classification of the SUNMOON's products is "Sensing and loT Technology"-sensor manufacturing and sensor application technology, information acquisition and processing technologies,loT technology and applications.These is the pioneer of modern high technology.The SUNMOON products are positioned to "reliably and steadily meet the harsh environment of the industrial site". The whole products system with forward-looking technology, application is convenient, the configuration is universal, now has more than 9000 number of clients from all walks of life. Have SM series weighing, load, pressure, torque, displacement, velocity, temperature and humidity sensors and the corresponding transmitter or amplifier, an annual output of 300 thousand units; an annual output of 20 thousand sets of all kinds of instrument; all kinds of projects completed 2000 terms of the annual capacity.The SUNMOON take Nanjing City as a scientific research base, making full use of Nanjing's talent advantage and international interests.With Bengbu City covers an area of 50,000 m'as the production and after-sales service base, and with local service as the goal, all the branches in different parts of the Country have jointly formed a complete scientific research, production and after-sales service system platform, which guarantees that The SUNMOON are in the lead of science and technology, innovation and forever the first. These is the SUNMOON's core competitiveness of the mechanism!  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
