Bipolar Hall-Effect Digital Position Sensor ICs: 32312814 SS41, SS41-L, SS41-T2, SS41-T3, SS41-S, SS41-SP Issue B Datasheet FEATURES Small, leaded, flat TO-92-style package allows for a compact PCB layout Wide operating voltage range of 4.5 Vdc to 24 Vdc allows these sensors to be used in a variety of applications Current consumption of only 5 mA max. at 4.5 Vdc for energy efficiency Bipolar magnetics for ring magnet applications with alternating North and South poles Robust design: Will operate up to 150C 302F RoHS-compliant materials meet Directive 2002/95/EC POTENTIAL APPLICATIONS DESCRIPTION Industrial: Speed and RPM (revolutions per minute) sensing, These small and versatile digital Hall-effect devices are tachometer, counter pickup, flow-rate sensing, brushless dc operated by the magnetic field from a permanent magnet (direct current) motor commutation, motor and fan control, or an electromagnet, and are designed to respond to robotics control alternating North and South poles. The built-in regulator Transportation: Speed and RPM (revolutions per minute) provides enhanced stabilit y of operation from 4.5 Vdc to sensing, tachometer, counter pickup, motor and fan control, 24 Vdc supply voltage range, and internal circuitry is designed electric window lift, convertible roof position to prevent sensor damage in case the supply voltage polarity Medical: Motor assemblies, medication dispensing control is accidentally reversed. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic PORTFOLIO circuits. The SS41 is tested at both 25C 77F and 125C Other bipolar digital position sensor ICs include: 257F . For design flexibility, these product are available in SS400 Series. SS500 Series (selected catalog listings) the following flat TO-92 package styles: SS311PT, SS411P SS41: Straight standard leads, bulk pack SS40F, SS40AF SS41-L: Straight long leads, bulk pack SS51T SS41-T2: Formed leads, ammopack tape-in-box SS30AT, SS40A, SS50AT SS41-T3: Straight standard leads, ammopack tape-in-box SS41-S: Surface mount, bulk pack SS41-SP: Surface mount, pocket tape and reel Sensing and Internet of ThingsBipolar Hall-Effect Digital Position Sensor ICs: SS41, SS41-L, SS41-T2, SS41-T3, SS41-S, SS41-SP Table 2.
