SD-R10C-T01 Rotary Encoder Switch | 10 Position SMD with Shaft | for Access Control / New Energy / Industrial Control

Product Overview

The SD-R10C-T01 is a 10-position rotary encoder switch introduced under the BONSDA brand. It features a 7.2×7.2mm mini SMD package with a long-shaft, lever-type design. The product provides 10-position (0–9) encoded output. By rotating the knob, users can set address codes or function codes. Each position is secured by a mechanical detent, ensuring intuitive and reliable operation.

In terms of performance, the SD-R10C-T01 adopts a four-pin SMD package and is compatible with reflow soldering, making it suitable for automated placement, improving production efficiency, and reducing assembly costs. Both the contact plate and terminals are gold-plated, with contact resistance as low as 60mΩ Max, insulation resistance of 100MΩ Min, and dielectric strength of 250V AC, ensuring stable and reliable signal transmission and reducing encoding read errors caused by poor contact. The operating force is controlled at 100–200gf·cm, providing a distinct rotational feel and accurate position detents, making it resistant to encoding shifts caused by vibration or accidental contact.

The product offers strong environmental adaptability, with an operating temperature range of -40°C to +85°C, suitable for complex temperature environments such as outdoor access control, EV charging stations, and industrial control. It has been verified through high-temperature storage, low-temperature storage, damp heat, thermal cycling, and salt spray tests. After testing, the contact resistance remains ≤200mΩ, insulation resistance ≥10MΩ, with no signs of mechanical or electrical performance degradation.

In terms of lifespan, under a resistive load of 100mA and 5V DC, the 0–9 positions can complete 12,000 cycles of operation, meeting the needs of frequent daily encoding setup and debugging while reducing after-sales maintenance frequency. All components comply with the EU RoHS directive, meeting environmental compliance requirements for exports to the EU.

The SD-R10C-T01 is widely used in access control equipment, new energy charging stations, inverters, circuit breakers, GDS control boards, home motor controls, meteorological instruments, EMS controllers, headsets, fruit sorters, industrial control, servers, control panels, regulators, PLC controllers, communication equipment, audio systems, and energy and power equipment. It is used for device address code setting, function mode switching, communication parameter configuration, and device numbering. It is a domestically produced encoder switch suitable for multiple application scenarios.
