Speed Switch Sensors 4B's line of speed switches include: proximity, inductive, zero speed and stop motion to monitor dangerous belt slip, underspeed or stop conditions on conveyors, bucket elevators and any other shaft driven machinery. Inductive Proximity Sensors 4B's line of inductive proximity sensors are designed to detect shaft speed, shaft position, gate position, or object presence.When you are troubleshooting your vehicle speed sensor, there are several things that you need to look at.

This could end up affecting your transmission, speedometer, ABS, power steering, and your cruise control. A vehicle speed sensor works a lot like a wheel speed sensor. As soon as you start to notice any problems with the aforementioned areas of your vehicle, you need to start troubleshooting immediately, so that you can fix the problem before it gets worse.

Allowing it to go undiagnosed and unfixed will end up costing you a lot more in the long run. Testing the speed sensor is simple enough, and can be done without a professional or any expensive equipment. If you are dealing with a sensor that is a variable reluctance type, then there will be a permanent magnet that is wire wrapped. It has a magnetic field that partly collapses, thanks to a toothed ring. When your magnetic field collapses, there will be a voltage induced into the wire that is wrapped around said magnet.

You can test this with an ohmmeter. If there is an infinite reading, then this is a sign that there is no electricity going through. If using an analog ohmmeter, then it will show this by staying on the same side as when there are no probes touching. If you use a digital ohmmeter, then there will be no value shown. There are two tests that you can do that will help identify a sensor that is bad. Use an OHM meter to test the integrity of the circuit of the sensor.

This is to check for an open winding. Your sensor should be able to read some type of resistance. The other test is with a scan tool. Install the scan tool, and set it for a data stream. The vehicle will need to be driven, as you monitor the signal of the sensor. Take note of the code that shows up on the scan tool and look up what this code means.

If you happen to have a later model vehicle, then your car will probably use the controller area network protocol. This particular sensor gives you a digital signal that will be on the actual on-board computer in your vehicle. Test this with the help of a resistive magneto sensor.

With this sensor, an electromagnetic field is powered by the computer. The built-in resistive bridge circuit processes the signal that is given to it, in the form of a digital square wave.Rotational or linear speed can be measured using a variety of magnetic sensors.

You may also find the product or information you need on one of the below pages:. For the detection of gears, rack gears, and other ferrous targets such as tone wheels, bolt heads, steel pins, rotating wheels, or discs there are two different magnetic sensing technologies to choose from. To learn more about selecting or designing steel targets for Speed Sensors we offer an Application Note.

For detecting moving targets at greater distances, magnets can be attached to any object and then be detected using Hall Effect switches. These sensors provide a digital output that turns on when a magnet is passing the sensor face. Standard Hall Switches only detect the South Pole of the Magnet, but either pole Hall switches can be used in applications where the magnetic pole orientation is not known or cannot be guaranteed.

The operate gap range is dependent on the sensor sensitivity and the size, shape, and material of the magnet.

Speed Sensors for Detecting Steel Targets For the detection of gears, rack gears, and other ferrous targets such as tone wheels, bolt heads, steel pins, rotating wheels, or discs there are two different magnetic sensing technologies to choose from.

Hall Effect Gear Tooth Sensors with back biasing magnetic structures detect the changes in the internal magnetic field when the gear teeth or other ferrous targets pass by the sensor face and output a digital square wave pulse train. Variable reluctance sensors use an internal coil, pole piece, and magnetic structure to generate a sine wave voltage output from passing gear teeth. Speed Sensors for Detecting Magnetic Targets For detecting moving targets at greater distances, magnets can be attached to any object and then be detected using Hall Effect switches.

Need More Information or a Quote?A vehicle speed sensor is a permanent magnet generator attached to the transmission under the vehicle. The sensor monitors several different engine and transmission functions and sends the information to the on-board computer. It is triggered by the turning of the transmission shaft, sending a signal which increases or decreases in frequency with the vehicle's speed.

This information is then relayed to the speedometer. If you suspect you have a problem with the speed sensor in your vehicle, you can check its operation with the help of a voltmeter. Raise the front of the vehicle and then set it down to rest securely on jack stands. Chock the rear wheel to prevent movement. Locate the speed sensor attached to the rear section of the transmission. Follow the wire from the sensor and disconnect it from the wiring harness where it is attached to the frame.

With the ignition on but the engine not running, push the probes of a voltmeter into the reference wires in the connector.

If no voltage is recorded, there may be a problem with the input signal from the on-board computer. Have the vehicle checked by a dealer service department.

Reconnect the harness and turn the ignition off. Remove the electrical connector from the speed sensor, and then remove the bolt that secures the sensor to the transmission housing. Gently withdraw the sensor from the transmission. Place the sensor on a bench and check the pulsing AC voltage with the voltmeter as you slowly turn the gear by hand. If there is no voltage, the sensor may be defective. Install the new sensor into the transmission and replace the retaining bolt.

To simplify installation, magnets are mounted in an aluminum disk which we refer to as a Magnetic Disk. Phares Magnetic Disks are designed for industrial machine speed monitoring.

They improve zero speed switch response time and industrial tachometer update time, especially for slow speed applications. They are compact and very effective. Phares Magnetic Sensor Targets and Magnetic Disks are designed for applications where vibration, dirt, dust and grime are present. Magnetic fields are unaffected in these environments and our Hall Effect Sensors and Zero Speed Switches are able to accurately sense a magnetic target under these conditions.

For applications where space is limited, individual Magnets, Magnetic Rings, and Split Disks are available. The table below shows Phares Magnetic Disks which are typically in stock. Custom Magnetic Disk types, diameters, and bore sizes are available, including split disks which are used to clamp around a shaft. Need help selecting a Magnetic Disk?
