10 / 14 page 10 sensing.honeywell.com SS360PT/SS460P. Features: Fastest response time in its class • No chopper stabilization • High sensitivity • Internal pull-up Hall IC design • Latching magnetics • Subminiature package size with tape and reel packaging • Small, flat TO-92- style package • Wide operating voltage range of 3 Vdc to 24 Vdc • Built-in reverse voltage capability • Robust design • RoHS-compliant meets directive 2002/95 Benefits: Fastest response time in its class provides more efficiency in commutating a brushless dc motor. No chopper stabilization results in a clean output signal. Operates from only 30 Gauss typical, at 25 °C [77 °F] and 55 Gauss maximum over the full -40 °C to 125 °C [-40 °F to 257 °F] temperature range, allowing for the use of smaller, magnets or a wider air gap. Internal pull- up Hall IC design simplifies installation and helps reduce component count and system cost. Latching magnetics make these products well-suited for accurate speed sensing and RPM (revolutions per minute) measurement. Sub-miniature, SOT-23 surface mount package (SS360PT) supplied on tape and reel allows for compact design with automated component placement. Small, leaded, flat TO-92-style package (SS460P) allows for a compact PC board layout. Wide operating voltage range allows for potential use in a wide range of applications. Built-in reverse voltage capability enhances the protection of the sensor and the circuits. Robust design allows operation up to 125 °C [257 °F]. Potential industrial/commercial applications include brushless dc motor commutation for white goods and other appliances, flow rate sensing, speed and RPM sensing, tachometer and counter pickup, and motor and fan control. SS361cT/SS461c. Features: Enhanced sensitivity • Latching magnetics • Subminiature package size with tape and reel packaging (SS361CT) • Small, flat TO-92-style package (SS461C) • Simple activation from a North pole (SS361CT) or a South pole (SS461C) • Built-in reverse voltage capability Benefits: Enhanced sensitivity allows operation from only 50 G typ. at 25°C [77 °F], 80 G max. at 60 °C to 85 °C [140 °F to 185 °F], and 95 Gauss over the full temperature range of -40 °C to 125 °C [-40 °F to 257 °F], allowing the use of smaller, potentially lower-cost magnets or wider air gaps. Wide operating voltage range of 4 Vdc to 24 Vdc for use in wide range of potential applications. Subminiature package size (SS361CT) uses less space on the PCB than standard Hall-effect sensor packages such as TO-92 or SOT- 89, allowing for use in smaller assemblies. Tape and reel packaging (SS361CT) allows for automated component placement, helping to reduce manufacturing costs. Small, flat TO-92-style package (SS461C) is also available. Built-in reverse voltage capability enhances protection of sensor and circuits with which it is used. Latching magnetics respond to alternating North and South poles, making these products well-suited for accurate speed sensing and RPM measurement. Potential applications include tachometer, counter pickup, motor and fan control, flow-rate sensing for appliances, robotics control, and medical equipment using electric motors. SS361RT/SS461R. Features: Latching magnetics • Enhanced sensitivity • Subminiature package size (SS361RT) • Low voltage: 3 V operation • Built-in reverse polarity protection • Robust design: will operate up to 150 °C [302 °F] • Through-hole and surface-mount (SOT-23 and SOT-89) packages Benefits: Enhanced sensitivity often allows for the use of less expensive magnets. Small size requires less PC board space, allowing it to be used in smaller assemblies. 3 V capability allows for use in low voltage applications, promoting energy efficiency. Available on tape and reel for most high volume applications. Potential applications include speed and RPM sensing, brushless dc motor commutation, tachometer, counter pickup, motor and fan control, electric window lift, convertible roof position and automotive transmission position detection, flow-rate sensing, robotics control. SS400/SS500 Series. Features: Unipolar, bipolar, latching magnetics • Sinking output • Multiple operate/release points available • Temperature compensated magnetics with negative slope • High output current capability • Small through-hole and surface-mount (SOT-89) packages • Tape and reel available Benefits: Quad Hall element design minimizes effects of mechanical or thermal stress on output and provides stable output. Negative compensation slope optimized to match negative temperature coefficient of lower cost magnets, providing robust design over wide temperature range. Band gap regulation provides stable operation over supply voltage range. Potential applications include speed and RPM sensing, brushless dc motor commutation, motor and fan control, magnetic encoding, disc speed, tape rotation, flow-rate sensing, lid and door closing detection, and position sensing. SS41/SS51T Series. Features: Bipolar magnetics • Sinking output • High output current capability • Reverse polarity protection Benefits: Built-in regulator provides enhanced operational stability over supply voltage range. Open-collector digital sinking output voltage easily interfaces with wide variety of electronic circuits. Internal circuitry prevents sensor damage in case supply voltage polarity is accidentally reversed. Potential applications include brushless dc motor commutation, motor and fan control, magnetic encoding, and tape rotation sensing. SS421 Series. Features: Bipolar magnetics • Sinking output • Active high and active low versions • Adjustable speed trip point with external resistor and capacitor • Temperature compensated Benefits: Internal circuitry contains timer so that one or two pulses at slower repetition rate than set point do not produce unwanted output. Small amount of hysteresis built into output provides operation right at set point and does not result in chattering output. User- |
