When it comes to potentiometers in the 35mm series, those familiar with Sibo products will surely think of Sibo's star products first— the conductive plastic potentiometer WDD35 series, as well as the digital potentiometers WDH series and WLH series. Now, let me show you the characteristics of these 35mm series products!

I. Conductive Plastic Potentiometer - WDD35 Series

As a star product of Sibo, the WDD35 series offers a variety of models for you to choose from: WDD35D4 / WDD35D1 / WDD35S / WDD35D8T. Since its introduction to the market, this series has received numerous praises.

Introduction to Conductive Plastic Potentiometer

Conductive plastic potentiometers consist of a substrate and a conductive plastic layer on its surface, which we commonly refer to as the element. During use, when the wiper moves on the surface of the element, the resistance value between the output terminal of the potentiometer and terminals 1 and 3 changes accordingly.

Advantages: Infinite resolution, high-speed tracking, long lifespan.

Installation Method

Generally speaking, screw mounting is used, which is a relatively simple way of installation. Usually, only tightening 2-3 screws can complete the installation process. However, because the product's housing cannot rotate, zero setting is not very easy, suitable for occasions where disassembly is not frequent. If it is needed to conveniently adjust the output of the product during installation, the servo slot on the potentiometer is useful. When selecting screws for screw mounting potentiometers, it is important to use the screws provided with the product as much as possible. Do not use screws that are too long, especially when installing linear displacement potentiometers, as screws that are too long may damage the internal resistors.

Application Fields

Used in industries such as shipping, tension control, and construction vehicles.

II. Digital Potentiometer - WDH Series & WLH Series

The 35mm digital potentiometer "household" is big, including products such as WDH35A / WDH35B / WDH35G / WDH35H / WDH35L from the WDH series, and WLH35A / WLH35B from the WLH series, all of which are outstanding products in the 35mm potentiometer category.

Introduction to Digital Potentiometer

The WDH series/WLH series of digital potentiometers use non-contact magnet-sensitive principles and have characteristics such as long lifespan, no dead zone, and high accuracy. They can provide various signal outputs and can customize electrical performance according to customer requirements.

Optional Product Features

①    Can provide any angle within 20o to 360o. In the non-effective rotation angle area, high-

end keeping, low-end keeping, both ends keeping, or angles specified by customers can be used for keeping.

②Standard output is 0 ~ 100%; voltage signals of any output range can be provided according to customer requirements, such as 10% ~ 90% output, etc.

③Can set 3 ~ 6 horizontal or rising output segments according to customer requirements.

④Standard signal output is clockwise, but can also be set to counterclockwise signal output.

⑤Can achieve special wide voltage input of 9 ~ 30V, 4 ~ 20mA/0 ~ 20mA output; PWM output, etc.

⑥Can provide special shaft length, special shaft diameter, or special processing on the shaft according to customer requirements.

⑦With a stop bit (345o), special mechanical rotation angles such as 270o, 180o, 90o can be provided, or specified by customers.

⑧Can provide products with light torque<0.5mN·m or high torque <30mN·m.

⑨Can provide products with special protection levels above IP54.

Installation dimensions are the same as WDD35 conductive plastic potentiometers

Whether it's diameter, positioning dimensions, arrangement of mounting holes, or shaft end dimensions, the digital potentiometers of the WDH series and WLH series are exactly the same as WDD35, ensuring that users can replace WDD35 without redesigning and adjusting the mounting panel, and can be used directly.

III. Committed to Quality, Your Trust, Sibo's Persistence!

The introduction to the 35mm series products is now complete. I believe everyone is eager to know how Sibo products achieve simultaneous control of quality and cost, right? Here, I can reveal a little secret of Sibo, which is to use automated testing equipment, replacing manual labor with machinery to ensure quality and reduce costs. This year, Sibo has upgraded its testing equipment and introduced the "Angle Displacement Potentiometer Comprehensive Test Bench", which comprehensively tests potentiometers from ten dimensions. We will also provide this equipment to customers and friendly competitors. If you are interested, please feel free to contact us at any time!
