Check the listing for details. Precision potentiometer CPP-50 sensor 5K 10K 2K 1K variable resistor. Condition: New. Listed at 125.00 USD. Working principle Use the angle change of the displacement detector (CPP-50) to generate the increase or decrease of the analog signal voltage to control the synchronous operation of more than two motors. It is also possible to set the tension and the weight to detect the operation individually. The main input and output voltage of the controller are displayed, and the upper and lower limits, the center point, and the zero indicator light indicate convenient monitoring and control. 1. The detector is fully airtight, with good surface moisture and dust resistance, good rotating wear resistance, and long service life. 2. The output voltage changed by the controller is output proportional to the main speed voltage, which can be more stable in high and low speed operation. 3. The detector or controller can also be used with other sensors such as speed, pressure, angle, etc. Shipping 1.Item will be shipped within 2-4 business days upon receipt of payment ,we can ship it from DHL. fedex ,Singapore Post.Hong Kong Post, china Post or many other delivery service, please choose which delivery service do you need . 2.Please confirm your address after you bid the item.
