• Tech Express 20Pcs A3144 A3144E OH3144E Hall Effect Sensor, by

    The A3144 is an integrated Hall effect non-latching sensor. Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. If a magnetic flux density larger than threshold Bop, the output is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing the output to be turned off (high) (see datasheet bellow). Features: Superior Temp. Stability for Automotive or Industrial Applications 4.5 V to 24 V operation, works with most unregulated supplies Open-Collector 25 mA output, compatible with digital logic Reverse Battery Protection Activate with Small, Commercially Available Permanent Magnets Solid-State Reliability Small Size Resistant to Physical St...

  • SunFounder Switch Hall Sensor Module for Arduino and Raspberry Pi

    Introduction A switch Hall sensor module that is composed by a switch Hall sensor, resistor and capacitor in an integrated circuit. For your reference: Based on the Hall Effect, a Hall sensor is a one that varies its output voltage in response to a magnetic field. Hall sensors can be categorized into linear (analog) Hall sensors and switch Hall sensors. A switch Hall sensor consists of voltage regulator, Hall element, differential amplifier, Schmitt trigger, and output terminal and it outputs digital values. Application The module can be applied to measurement of revolution, revolving speed, wind speed, flow speed, proximity switch, door lock notification device, alarm, auto-control circuit, etc. Component List - 1 x Switch Hall sensor module - 1 x 3-Pin anti-reverse cable

  • HME301 Hall Effect Sensor Component - Replacement for HKZ101, HKZ101S, HKZ121, CYHME301

    The HME301 Hall Effect Sensor was designed to take the place of several sensors that are no longer produced. Because these sensors eventually wear out, it's important to have them available to keep older cars and motorcycles running properly. These sensors are also commonly used in industrial machinery, electronic injection, automation, and many other industrial applications -- RPM sensors, limit switches, position sensors, speed measurements, shaft encoders, etc. Modern design and manufacturing methods have produced replacement sensors that are better than the originally-specified components, featuring better accuracy, endurance, narrow temperature drifting, a smooth and clean output curve, and non-instantaneous dithering. HME301 is a non-contact sensor/switch, which consists of a monolithic integrated Hall Effect circuit and a special magnetic circuit hermetically sealed in a plastic housing. The housing is waterproof, resistant to vibration, gasoline, oil and salt. Two tubular rivets are incorporated in the package to mount the sensor on the carrier plate. The sensor has three leads for power supply, output and ground.

    These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. The four basic devices (3141, 3142, 3143, and 3144) are identical except for magnetic switch points.

  • Hall Effect Crankshaft Position Sensor

    Hall effect crankshaft or camshaft position sensor. We've tested this with our 6.75" and 8.25" trigger wheels. We were able to get a rock solid reading at over 19,200 RPM, which is as fast as our test rig could spin the trigger wheel. Runs off 5 to 24 volts, and gives a nice square wave so there's no variable voltage issues. Has a 12 inch long, 3 wire pigtail. Here's what the wires do: Red - Supply voltage; connect to either VREF or 12 volt switched power. White - Output signal. On a MegaSquirt, connects to pin 24. We just set our MegaSquirt up for the VR conditioner and it works great. V3.0 MicroSquirts can also do this, but older MicroSquirts will need to use the Hall effect input. Black - Ground. Specifications Operating voltage: 4.75 to 24 volts Maximum overvoltage and reverse voltage: +27 to -25 volts Maximum output current: 20 mA Maximum frequency: 15 kHz Temperature range: -40 to +125 degrees C Maximum air gap: 5 mm Please see product photo's for diagram.

  • RobotDyn - Hall magnetic Sensor with analog & digital outs. Proximity magnetic detect.

    The Hall Effect Magnetic Sensor can be used for detect the presence (or absence!) of nearby objects such as magnets. If no magnetic field is present, the signal line of the sensor is HIGH (on digital out). If a magnetic field is presented to the sensor, the signal line goes LOW (on digital out), at the same time the LED (blue) on the sensor lights up. The distance detection to a magnetic object can be adjusted via the potentiometer on board. It also has the Analog output, to determine the magnitude of a magnetic field or the distance to a object. The polarity of the magnetic field is of influence to the switching action. The front side of the sensor needs the opposite polarity as the back of the sensor to switch on. Connection: GND = to GND VCC = to 5V DO = to any Digital I/O AO = to any Analog In RobotDyn(R) - registered trademark in USA. Zhuhai RobotDyn Technology Co.,Ltd - Developer and manufacture.
