Expanding its magnetic position sensor product portfolio, Honeywell introduced the SS360NT/SS360ST/SS460S high sensitivity bipolar latching digital Hall-effect sensor ICs. Bipolar latching magnetics make these products well-suited for accurate speed sensing and rpm measurement. For brushless DC motor manufacturers that need latching sensor ICs with reliable, consistent performance for efficient and small designs, these sensor ICs respond to low magnetic fields and offer consistent repeatability while providing the fastest response to a change in magnetic field for enhanced motor efficiency. They feature reliable switching points with high magnetic sensitivity of 30 G typical (55 G maximum) without using chopper stabilization on the Hall element, resulting in a clean output signal and the fastest latch response time in its class. These small, sensitive, and versatile devices are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles. The sensors can be used in a wide range of applications. Potential industrial/commercial applications include brushless dc motor commutation, flow-rate sensing for appliances, speed and rpm sensing, tachometer/counter pickup, motor and fan control, and robotics control. Potential transportation applications include speed and rpm sensing, tachometer/counter pickup, motor and fan control, electronic window lifts, and convertible roof position. Potential medical applications include medical equipment that utilizes electric motors. These devices operate over the full temperature range of -40 to 150 °C. They have a wide operating voltage range of 3 to 24 Vdc. Built-in reverse voltage enhances the protection of the sensor and the circuits. Their durable design allows operation up to 150 °C. Additionally, RoHS-compliant materials meet Directive 2002/95/EC.
