Product Description

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 work

The 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 performance

1. Basic performance

• Fixed examination distance:≤3mm
• Measures 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-wave
Occupies the spatial ratio:0.5±0.2
Protection 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 ºC
