Hall-Effect Zero Speed Sensor (HS)
Non-contact magnetic sensors that measure the distortion of magnetic field created by a ferrous target. These sensors provide very precise measurements of movement even at zero speed which makes them ideal for speed measurements. These sensors provide digital output with constant amplitude signal regardless of variation of the speed. |

Hall-Effect Quadratur Sensor (HQ)
Non-contact magnetic sensors that measure the distortion of magnetic field created by a ferrous target. These sensors provide two 90ยบ out of phase digital outputs to record speed and direction. When the target wheel or gear is rotating clockwise, the output signal # 1 leads output signal # 2, and when the target is rotating counter clockwise, the output signal # 2 leads output signal # 1. Both output signals will be 50% duty cycle with proper alignment of sensor and target gear. |

Hall-Effect Speed and Direction Sensor (HD)
Non-contact magnetic sensors that measure the distortion of magnetic fields and thus provide precise measurements of speed and direction. Output #1 is digital square wave and measures the speed of target wheel or gear. Output #2 is a DC level that when the target wheel rotates clockwise, the output signal # 2 produces logic High, and when the target wheel rotates counter clockwise, the output signal # 2 produces logic low. Output signal #1 will be 50% duty cycle with proper alignment of sensor and target gear. |

Hall-Effect Linear Position Sensor (HL)
Non- contact magnetic sensors that are designed to respond to a wide range of positive or negative magnetic fields and can sense relatively small changes in a magnetic field. By having magnet as a target, this unit produces a Ratiometric Rail-To-Rail linear output. It also has an internal amplifier to boost the output to a higher level. These sensors are ideal for applications such as magnetic flux measurement, displacement, and linear output rotary measurement. |

Hall-Effect Proximity Switch Sensor (HP)
Non-contact magnetic sensor proximity switch produces a digital output. The output switches between logic low (operate point) and logic high (release point) with presence and absence of a magnet as a target. The difference between the magnetic operate and release points is called the hysteresis of the device. The built-in hysteresis circuitry allows clean switching of the output even in the presence of external mechanical vibration and electrical noise. |

Variable Reluctance Speed Sensor (VR)
The collapse of magnetic field due to the interruption by a ferrous gear tooth provides an analog signal output (sine wave) that does not require an outside power source. This sensor is suitable for speed sensing with a range from 30 to 1000 inches per second with a target gear from one tooth per revolution to 32 pitch gear. |

Variable Reluctance Digital Output Speed Sensor (VD)
Due to the active solid state signal conditioning integral with this variable reluctance speed sensor, it converts a sine wave signal output to produce a digital square wave signal with constant amplitude regardless of variations in speed. |
