Product Details:
Minimum Order Quantity1 Piece
Range2cm to 3m (~.75" to 10')
Supply Voltage5V +/-10% 3-pin interface (power, ground, signal)
Burst Frequency 40 kHz for 200 uS

The sensor measures distance using sonar; an ultrasonic pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as an infrared replacement if so desired.

    Thanks for Contacting Us.

    Product Details:
    Minimum Order Quantity1 Piece
    Input dynamic range160dB
    Measure light over a range100,000,000-to-1
    Output Power1 - 50W

    The sensor precisely measures light using an array of photodiodes, with an output of digital square waves. The programmable light-to-frequency converter combines a configurable silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated circuits. The output can be either a pulse train or a square wave with frequency directly proportional to light intensity. The sensitivity of the device is selectable and the output frequency can be scaled by one of four preset values. An output enable (OE) is provided that places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.

    Product Details:
    Minimum Order Quantity1 Piece
    Humidity range0 to 100% RH
    Returns temperature with a resolution0.01 degrees Celsius and relative humidity
    RatingIP67

    It is a smart sensor for both humidity and temperature, and it comes in a tiny package that incorporates the analog to digital interface. All that the microcontroller has to do is read out the humidity and temperature values through the two-wire digital serial interface. The only math required is a simple scale and offset. It is factory calibrated so that it returns temperature with a resolution of 0.01 degrees Celsius and relative humidity with a resolution of 0.03 percent. The accuracy is better than most other sensors too.


    Specifications:

    • Temperature range: -40 °F (-40 °C) to +254.9 °F (+123.8 °C)

      V-Tech DIN Abrasion tester (Abraser / Abrader), which is the oThe method conforming to ASTM D5963 / ISO 4649 has proven to be the best way of simulating long term wear. This method enables comparative tests for the control of the uniformity of a specific material. The achieved test results provide important parameters in respect to the wear of elastomers in practical use. The abrasion resistance is measured by moving a test pieceacross the surface of an abrasive sheet mounted to a revolving drum, and is expressed as volume loss in cubic millimeters or abrasion resistance index in percent.
      volume loss, a smaller number indicates better abrasion resistance, while for the abrasion resistance index, a smaller number denotes poorer abrasion resistance.index in percent. For
      The DIN Abrasion tester can also be used for comparative measurements on other materials such as plastics, chalk or painted surfaces.

      Accessories for DIN Abrasion Tester :

      Abrasive Sheet :

      An abrasive sheet will abrade approximately 210 ... 250 mg from the mass of a comparison sample. This abrasion should be reduced to approximately 210 ... 220 mg by abrading a steel sample across the entire width of the delivered drum once or twice. The sheet can be used as long as the abrasive loss of a comparison rubber sample is less than 180 mg. It has to be replaced then.

      Rubber Comparison Sample Sheet :

      The rubber comparison sample sheet serves for the determination of the degree of abrasiveness incompliance with ISO 4649 (Formerly DIN 53516). It is produced of a special mixed rubber. Each plate has a dimension of approximately 186 mm x 186 mm and enables the production of about 100 comparison samples of a thickness of 8 mm.

      Circular Cutting Unit :

      The circular cutting unit is used for the cutting of rubber samples with a diameter of 16 mm. The holder for the cutter is a morse taper No. 2 and can be fitted to a suitable drilling machine. Replacement Cutter Spare cutter : For the circular cutting unit. Increasing the sample pressure by 10 N An additional weight of 10 N allows an increase of the pressure in steps by 12,5 / 15 / 17,5 and 20 N.

      Drum Cleaning Unit :

      The drum cleaning unit consists of a set of brushes with holder, which is mounted on the rear of the sample holder and removes the dust from the abrasive sheet. A vacuum cleaner hose with a diameter of 40 mm can be connected to the brush holder. Replacement Brushes : For the drum cleaning unit

      Precision Balance :

      The precision balance with digital display, for the weighing of the sample, consists of a metal housing with a glass-protected weighing space. Weighing tray Ø 80 mm Weighing range: 0 ... 110 g Display step: 0,1 mg Reproducibility: ± 0,15 mg Linearity: ± 0,2 mg Mains connection: selectable 110/220 V, 50/60 Hz Dust Cover

        A complete color detector, including a sensor chip, white LEDs, collimator lens, and standoffs to set the optimum sensing distance.
        The sensor has an array of photo detectors, each with either a red, green, or blue filter, or no filter (clear). The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal to the device is an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color. The sensor can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few.
