HEDS Optical Encoder | Portescap

The output of this sensor is an analog voltage signal. An Arduino DIY Tachometer Display The goal of this project was to create some sort of display that would retrieve and display the rpm signal in an easy to read manor. This easy-to-use hand held digital tachometer measures up to 99, RPM and features a large LCD display, laser pointer, low battery indicator, and memory recall for the last displayed value, minimum value, and maximum value.

Great for measuring rotating equipment such as motor shafts, engines, and gears.

To take an RPM measurement without the addition of reflective tape, you will require a contact tachometer. The optical sensor output is converted to a square wave and fed directly into a pin on the micro.

A tachometer is a useful tool for counting the RPM rotations per minute of a wheel or basically anything that spins. As the magnetic sensor passes along the magnetic scale, the sensor detects the change in magnetic field and outputs a signal.


DC motor speed control using optical 5500.

Optical tachometer with analog output

The OM02 produces a quadrature output for both X and Y directions of movement. Stay abreast of the latest at Portescap – press releases, articles, product introductions and much more.

The replacement tachometer is – Proximity Sensors are available at Mouser Electronics from industry leading manufacturers. This high-performance HEDS optical encoder is available in 2 or 3 channels.

With an emphasis on high quality product design, combined with a low cost base, Compact Instruments has geds high quality tachometers and speed measurement products The A Non-Contact Tachometer converts RPM into an analog voltage output signal allowing you to use any Digital Multimeter, Data Acquisition System or Voltage Recorder as an RPM display. Skip to main content. Get quality at a fair price. The output of the sensor is run through hexs LM comparator in the inverting comparator configuration.

A digital output produces a clean square wave that a robot microcontroller can use to determine motor speed and motor rotational direction. Contact a supplier or the parent company directly to get a quote or to find out a price or your closest point of sale.

If you want true high speed and direction AND easy zero speed detection, then you need to buy a tachometer-generator. Our original plan was to build an optical tachometer, but we discovered that a computer mouse has a optical encoder built into it.

As Engine Tachometer to measure engine revolution at the high-tension cords, and as laser tachometer to measure the RPM of any rotating objects. Can also include a combination of analog input channels, analog output channels, and thermocouple input channels. Digital input for analog tachometer circuit I’m using the digital output signal from it for this.


To overcome that problem, the encoder described on this page places the sensor and analog-to-digital converter on the same board.

Besides sound and vibration signals, most order analysis applications require an analog tachometer signal or a digital tachometer signal to provide a rotational reference. A tachometer is indispensable to measure and control accurately rotating devices which are used in various areas of industry as some kind of power output.

Configurations can be saved and quickly reloaded. Using the analog voltage reading property of an arduino, this can be easily implemented using the appropriate parts. Digital tachometers are used in different applications such as automobiles, aeroplanes, and medical and instrumentation applications.

It is generated whenever the “A” channel illumination passes through thelight.

Optical Encoder HEDS-5500

Tachometer with Analog Output. Every time a spark plug fires, the ignition system triggers a voltage pulse at the output of the tachometer electronics. Ability to track changes with analog and pulse output of RPM.

Over ten years ago, I put up a web page with detailed instructions on building a simple yeds motor based on one from the Beakman’s World TV show. The motor is rated for 30 Oz.
