High Precision Potentiometer

Industrial equipment, medical devices, and robot joints use potentiometers to send position signals to the control system. If accuracy is not good, the equipment will deviate. Hayi Technology's high precision potentiometer uses a precision resistance element and a metal wiper. Linearity can reach ±0.1%. Lifespan exceeds 1 million cycles. For example, a medical rehabilitation equipment company had potentiometers that started jumping after six months. We provided a conductive plastic potentiometer. It ran for two years with stable signals. This case shows the reliability of feedback components decides the lifespan of the whole machine. Our MOQ is 1 piece.

Conductive Plastic Element and Multi-Finger Wiper

We make wirewound, conductive plastic, and metal film types. Conductive plastic gives the best linearity, up to ±0.05%. The wiper uses multi-finger precious metal contacts. Contact resistance variation is less than 1%. Mechanical rotation is from single turn to multi-turn (10 turns). Shaft diameter is typically 6mm or 4mm. We hold ISO9001:2015 certification. Each potentiometer gets a full-stroke linearity test and a contact resistance variation test before shipping. We can also custom make shaft length and wiring style. Our high precision potentiometer can help your clients replace expensive imported brands.

Many clients need special resistance values or special shaft types. Our custom sample time is 1 day minimum. Standard order lead time is about 15 days. Payment: 30% deposit for standard products, 50% deposit for custom products, balance before shipment. Trade terms: EXW, FOB, DDP. Large orders get a discount. If any problem occurs, we talk immediately and improve after we find the cause. We have a dedicated after-sales person. Many clients used to buy from Bourns or Vishay at high prices with long lead times. We offer OEM and ODM service with the same quality at 30-40% lower price. Our technicians can help you match electrical parameters and mechanical dimensions. You can help your client lower cost without sacrificing quality.
