SS495 linear hall effect sensor v 2 . 0 0 may 1 , 20 12 1 3 pin sip (suffix ua) description SS495 linear hall - effect sensor is a small, versatile linear hall - effect device that is operated by the magnetic field from a permanent magnet or an electro magnet. the linear sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. specifically , w hen s495 is in the zero magnetic field conditions, the output voltage is half of the supply voltage. when south poles approach the s495 marking surface, the output voltage will increase linearly with the magnetic field strength ; on the other hand, north pole will cause output voltage decreases linearly with the increase in magnetic field strength . the integra ted circuitry features low noise output, which makes it unnecessary to use external filtering. it also includes thin film resistors to provide increased temperature stability and accuracy. the linear hall sensor has an operating temperature range of - 40 c to 150 c appropriate for commercial, consumer and industrial environments. typical applications e lectric vehicles speed regulation pedal motion detector gear sensing motor control magnetic code reading ferrous metal detector current sensing position sensing p roximity detector functional block diagram features miniature co nstruction low - noise output good consistency high sensitivity high reliability 4.5 v to 10.5 v operation voltages magnetically optimized package linear output for circuit design flexibility temperature range from - 40 c to 1 5 0 c
