About products:

SM39-SP-II speed sensor adopts U.S.A. to import the specialized integrated chip to design, it is that a kind of high-accuracy speed measures tools, have advantage such as being wide, non-maintaining of the loud high, good, working voltage range of dependability frequently.

The products are detailed:

SM39-SP-II speed sensor adopts U.S.A. to import the specialized integrated chip to design, it is that a kind of high-accuracy speed measures tools, have advantage such as being wide, non-maintaining of the loud high, good, working voltage range of dependability frequently. Pass the speed which measures the gear too indirectly to exposed to, thus achieve the goal that the speed measures. This product outputs and has a facelift the square wave signal by way of resisting electromagnetically and interfering with OC door with strong ability, can adjust, connect with logical circuits such as TTL, CMOS,etc. directly through pulling upward the resistance. Can also form rotational speed measuring, speed control system together with other appearances of testing the speed directly. Test the speed some ‘ Test the speed hair) Adopt the standard to manage the waterproof structure round, waterproof, dustproof and defending greasy dirt,etc. advantage, can work in the abominable environment reliably in midium or long term, the main shaft adopts the stainless steel to be designed, have ~s advantages of antirusting, resisting and abrading etc.. Have already applied to car, steamer and gathering and controlled field of high-accuracy industry extensively at present. Operation principle SM39-SP-II speed sensor adopts the advanced detection technique, can distinguish and turn over and measure Taxi every tooth carrying and tooth valley, turn into the cycle square wave to correspond to the speed. Technical feature Test the speed the intersection of hair and basic performance 1,Amount measures the distance: Less than or equal to 3mm 2, range of testing the speed: 10 rpms (every ext. a tooth) -20,000 rpms (every ext. 60 teeth) 3,Output waveform: Square 4 wave, take empty than: 0.5± 0.2 5,Protect the function: There is power transposition that protects and outputs and shorts out to protect temperature 6, working: Regular products – 40 – + 85 ℃, have special requirement please customize, maximum temperature can reach 150 ℃Electric performance

OC door

Control the voltage 16V the most largely, pass the electric current 25mA continuously the most largely

The high voltage puncturing type, puncture the voltage 160V the most largely; Allow to pass the electric current 600mA continuously the most largely; Allow the maximum consumption, 625mW, is higher than 25 ℃, decreasing 5mW / ℃ at 25 ℃
