Magnetic Sensor ICs & Value-added Packages

You know us as a leader. In 1968, we revolutionized the industry with the first solid-state keyboard combining
Hall-effect sensing and associated electronics in a single circuit. These high-speed, extended life sensors are
often directly compatible with other electronic circuits, responding to the presence or the interruption of a
magnetic field by producing a proportional output.
Supply voltage as low as 2.2 Vdc, combined with very low average current of 1.8 μA typ., reduces power consumption, provides extended battery life, and promotes energy efficiency. Push-pull output does not require external pull-up resistor, simplifying interface with common electrical circuits and potentially reducing PC board space and costs to the customer. Does not utilize chopper stabilization, eliminating the noise generated by products using this technique, meaning that customers do not need filters to compensate for the noise. Omnipolar capability with high and low duty cycle options allows for use in a variety of potential applications with low power requirements and/or battery operation. Thermally balanced integrated circuit provides for stable operation over a wide temperature range, of -40° to 85 °C [-40° to 185 °F]. SOT-23 subminiature package requires less PCB space, allowing for use in smaller assemblies. North pole or South pole operation does not require the magnet polarity to be identified, making installation easier and potentially reducing system costs. Supplied on tape and reel which allows for a compact design with automated component placement, helping to reduce manufacturing costs. Potential applications include motion control, lid closure detection, presence-absence, metering, and displacement sensing on battery-operated, mobile equipment such as computer notebooks, scanners, handheld industrial computers, instrumentation and appliances.

Design and manufacturing platform-based approach enables cost competitiveness and mechanical and electrical configurability. Provides both speed and direction information: speed from digital square wave outputs; direction using a quadrature output with signals 90° phase shifted from each other, target direction determined by output lead/lag phase shifting. Designed for applications where enhanced accuracy is required to detect small target features. Enhanced accuracy enabled by dual differential Hall effect sensor IC technology. Designed for wide operating temperature range, robust electrical noise immunity and industry leading environmental sealing capability. Potential industrial applications include power control in heavy duty vehicle ac induction motors and hydraulic pumps, speed and position control in escalators and elevators. Potential transportation applications include power regulation control of hybrid electric transmissions and engines in heavy duty vehicles, wheel speed detection in material handling, agriculture and construction machines.
Provides speed and direction information using quadrature output with signals 90 degree phase shifted from each other. BiCMOS Hall-effect technology, using advanced digital signal processing for dynamic off-set cancellation, provides enhanced air gap performance and phase shift accuracy over most conditions. Package design includes O-ring seal for potential pressure applications and a fixed mounting flange. Robust, automotive under-the-hood grade packaging for most environmental conditions as well as EMI hardened. Used in potential applications where high resolution is required at wide frequency ranges and large air gaps.
Available in several diameters and lengths for application flexibility. Stainless steel package simple to install/ adjust and does not require rotational orientation. Potential applications include harsh environment rotary applications such as pumps, rollers, mixers, fan speed measurement, transmission, spindles, gear reducer RPM, synchronization, compressor speed, and dyno testing, as well as industrial process control and factory automation.

Aluminum package simple to install/adjust and does not require rotational orientation. Potential applications include harsh environment rotary applications such as pumps, rollers, mixers, fan speed measurement, transmission, spindles, gear reducer RPM, synchronization, compressor speed, and dyno testing, as well as industrial process control and factory automation.
Use a magnetically biased Hall-effect integrated circuit to accurately sense movement of ferrous metal targets. The specially designed IC (integrated circuit) and a permanent magnet are sealed in rugged, probe-type packages. The flux density of the permanent magnet alters when approached by ferrous metal and is detected by the Hall ICs. If the sensor is positioned at the circumference of a revolving gear wheel, for example, it detects the teeth and tooth spaces, supplying a digital pulse output with frequency proportional to gear wheel speed. Potential applications include tachometers/counters, speed of gears and shafts in transmissions, hydraulic motors, pumps, and gear boxes flow meters/ turbines, and engine RPM.
Package provides physical protection and cost-effective installation. Electronically self adjusts to slight variations in runout and temperature, often simplifying installation and maintenance. Potential applications include transportation camshaft and crankshaft speed/position, transmission speed, tachometers, and anti-skid/traction control; industrial sprocket speed, chain link conveyor speed and distance, stop motion detector, high speed, low-cost proximity, tachometers and counters.
