WDD35D-4 Precision Conductive Plastic Potentiometer 05% Angular Displacement Sensor 1K 2K 5K 10K Overview: The conductive plastic angular displacement sensor is a displacement sensor with a linear relationship between voltage output and shaft rotation angle. It is characterized by high precision, long life and good output smoothness. The angular displacement sensor adopts the principle of a resistor divider. A constant DC voltage is connected across the resistance rail. The output is obtained by the movement of the brush on the rail. The output voltage is linear with the displacement. The index is expressed by linearity. The smaller, the higher the accuracy. The displacement sensor made by the principle of resistor divider can reduce the accuracy requirement of the total resistance of the rail, reduce the requirements of the sensor for the use of environmental conditions, and improve the accuracy of the sensor output signal. The angular displacement sensor structure is mainly composed of a conductive plastic substrate, a brush, a follower shaft, a casing and the like. The angular displacement sensor has several types, such as single unit and double unit. The electrical signal is generally taken out in the form of a terminal. Installation : 1 The diagonal displacement sensor is positioned by its own mounting boss, fastened to the metal plate with screws, and then connected to the center of the rotating body; 2 For the wiring of the angular displacement sensor, see the wiring diagram on the sensor (where “1” = zero phase of the sensor, “3” = input of the sensor, “2” = output of the sensor), and the connector is marked with 1, 2 3, corresponding to the schematic; the medium pumping series has four terminals, the specific wiring to view the size chart of the corresponding model. 3 The input and output of the angular displacement sensor are analog DC voltage signals, and the output voltage is determined by the input voltage (for example, input 5V, the output of the whole range is: 0-5V; input 10V, the output of the entire range is: 0-10V, and so on). matters needing attention: 1 The angular displacement sensor should not be disassembled or modified before installation (including tearing off the trademark, processing on the shaft and the housing, loosening the nail, rotating the fastening ring position, etc.). During the installation process, the angular displacement sensor should be handled gently to avoid damage to the terminal; 2 When the angular displacement sensor is connected to the line, it should be strictly in accordance with the schematic diagram on the sensor. Pay special attention to the "2" end is strictly prohibited to access the input voltage, otherwise burn out the sensor; 3 The current through the potentiometer is recommended to be 2mA, the maximum does not exceed 1OmA; 4 The external wiring of the angular displacement sensor should be welded to the waist groove at the leading end, and should not be welded to the top of the lead end. When welding, ferrochrome of not more than 45W should be used, and the welding time should be less than 5S. When welding and uncooling, the wire should not be pulled to prevent the wire or the entire leading end from being pulled out or even falling off. When welding, use flux and soldering oil as little as possible, and the time should be short to prevent the flux vapor from entering the potentiometer through the lead end (green), causing the vapor to be deposited on the surface of the resistive element after cooling to cause the equivalent noise resistance to deteriorate or even open; 5 The attack of the angular displacement sensor by solvents and corrosive gases should be prevented. Prevent metal chips or other powder from entering the angular displacement sensor; 6 When the angular displacement sensor is energized, be careful not to use the multimeter's electrical blocking and current gear to measure the potentiometer voltage; resistance pattern 1kΩ, 2kΩ, 5kΩ, 10kΩ Total Resistance Tolerance (%) ± 15 Product size: outer diameter * shaft diameter * shaft length 36.5mm*6mm*19mm theoretical electric trip (°) 345°±2° Mechanical course (°) 360 ° () Power Rating (W, at 70 ° C)) 2 W (70 ° C) temperature coefficient of the resistance ≤0. 04%/° C Insulation resistance (MΩ) ≥1000M Ω (500VDC) dielectric (v) 500 V (AC.
