Sensing and Control Honeywell Inc. 11 West Spring Street Freeport, Illinois 61032 Solid State Hall Effect Sensors High Performance Miniature Ratiometric Linear FEATURES • Small size (.160 x .118 in) • Power consumption of 7 mA at 5 VDC for energy efficiency • Single current sinking or current sourcing output • Linear output for circuit design flexibility • Built-in thin film resistors are laser trimmed for precise sensitivity and temperature compensation • Rail-to-rail operation provides more useable signal for higher accuracy • Temperature range of -40°C to +150°C • Responds to either positive or negative gauss • Quad Hall sensing element for stable output TYPICAL APPLICATIONS • Current sensing • Motor control • Position sensing • Magnetic code reading • Rotary encoder • Ferrous metal detector • Vibration sensing • Liquid level sensing • Weight sensing SS490 Series WARNING PERSONAL INJURY • DO NOT USE these products as safety or emergency stop devices, or in any other application where failure of the product could result in personal injury. Failure to comply with these instructions could result in death or serious injury. The SS490 Series MRL (Miniature Ratiometric Linear) sensors are small, versatile linear Hall effect devices which are operated by the magnetic field from a permanent magnet or an electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry provides increased temperature stability and sensitivity. Laser trimmed thin film resistors provide high accuracy (null to ± 3%, sensitivity up to ±3%) and temperature compensation. These linear position sensors have an operating temperature range of -40˜C to +150°C, appropriate for industrial and automotive environments. They respond to either positive or negative gauss, monitoring either or both magnetic poles. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The positive temperature coefficient of the sensitivity (+0.02%/°C typical) helps compensate for the negative temperature coefficients of low cost magnets, providing a robust design over a wide temperature range. Rail-to-rail operation (over full voltage range) provides a more usable signal for higher accuracy. The recent extension to the product line, the SS490B Series, offers costeffective MRL sensing solutions with slightly wider specifications than the SS490 high-performance products. Like the SS490 Series, the SS490B has a typical sinking or sourcing output of 1.5 mA continuous, uses 7 mA of supply current at 5.0 volts and 25˜C, and provides predictable performance over the full temperature range. The SS490B Series sensors have wider null and sensitivity tolerances and a wider drift over temperature. The SS490B Series sensors are a new lower cost product line extension. They complement the SS490 Series of small size, high accuracy and high performance miniature linear products.
