SS361RT/SS461R Bipolar Latch, Hall-Effect Magnetic Position Sensors DESCRIPTION The SS361RT’s small size requires less PC board space, The SS361RT/SS461R sensors are small, versatile digital Hall- allowing it to be used in smaller assemblies. Its 3 V capability effect devices that are operated by the magnetic field from a allows for use in low voltage applications, promoting energy permanent magnet or an electromagnet, designed to respond efficiency. to alternating North and South poles. The SS361RT is available on tape and reel; the SS461R is available in a bulk package (1000 units per bag). These bipolar latching sensors have enhanced sensitivity which often allows for the use of less expensive magnets. These sensors are available in two package styles, the SS361RT in the miniature SOT-23 surface mount package and the SS461R in the leaded, flat TO-92-style package. FEATURES POTENTIAL APPLICATIONS • Enhanced sensitivity Transportation: • Miniature package size • Speed and RPM (revolutions per minute) sensing • Low voltage: 3 V operation • Tachometer, counter pickup • Built-in reverse voltage protection • Motor and fan control • Robust design: will operate up to 150 °C [302 °F] • Electric window lift • Convertible roof position • Automotive transmission position Industrial: • Speed and RPM (revolutions per minute) sensing • Tachometer, counter pickup • Flow-rate sensing • Brushless dc (direct current) motor commutation • Motor and fan control • Robotics control Medical: • Motor assemblies • Medication dispense control

See Figure 1. NOTICE Bipolar Hall-effect sensors may have an initial output in either the ON or OFF state if powered up with an applied magnetic field in the differential zone (applied magnetic field >Brp and <Bop). Honeywell recommends allowing 10 µs for output voltage to stabilize after supply voltage has reached 5 V. Table 2. SS361RT/SS461R Absolute Maximum Ratings1 Characteristic Minimum Typical Maximum Unit Supply voltage -26.0 – 28.0 V Applied output voltage -0.5 – 28.0 V Output current – – 20 mA Magnetic flux – – no limit gauss Note: 1. The magnetic field strength (gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a uniform magnetic field. NOTICE Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will the device necessarily operate at absolute maximum ratings.
