Housed in a industry-standard gull-wing package to make them less susceptible to solder bridging, SS5 Series 1st level Hall-effect sensors are well-suited to applications such as automotive comfort, convenience and speed sensing, position sensing and motor control in computer cooling fans, disk drives and tape drives. Other uses are air cylinder piston detection, liquid or gas flow-rate detection, and rpm measurement. Operating voltage is 4.5 to 24 vdc for the SS51T and 3.8 to 30 vdc for the SS500.
