SIBO WLH35B/WDH35B/R36H Series Contactless Potentiometers

The users who are familiar with potentiometer, mostly know that mostly know that angular potentiometers by its mechanical limit cannot achieve 360° but only 320° to 355° effective electrical angle generally.

It leads to have blind areas problems in many applications. Non-contact potentiometers from SIBO emerged at the right moment in response to meet the diversified needs of customers. We called them ‘Contactless Potentiometers’.

However, general contactless potentiometers have shaft with only one side extension. It is harder for customers to buy the contactless potentiometers that have shafts with front and rear extension or through-hole form in the market. Devoting to solving customers' problems, SIBO brings you the patented products ----WDH35B/WLH35B/R36H series contactless potentiometers.

These series of contactless potentiometers, which are that our engineers conducted long-term research and development as well as testing, and adopted magnetic principle and unique structure, to achieve the function both with 360° effective electrical angle and shafts with front and rear extension or through-hole form. The products are widely applied in the tower crane industry, position limiter, actuators, steering engine feedback and other occasions. Let's take a look at the three series products in detail:

WDH35B

WDH35B, which has the same outside dimensions as the traditional potentiometer WDD35D4B that has the shaft with front and rear extension, can directly replace WDD35D4B. Its electrical specifications are available for 0505, 2410, 2405, or 2442.Single output or dual output is optional. Special mechanical specifications with stopper are also available.

WLH35B

WLH35B, which is the economic version of 35 series based on WDH35B, by compressing the structural space and optimizing the part structure, we reduce the production cost.. It has the same electrical specifications as WDH35B series, also available for 0505, 2410, 2405, or 2442, optional for single output or dual output. Due to the structure compacted, WLH35B series can not achieve the stopper function, but has the thinner and more economy advantages, so that the products are selected by more customers.

R36H

R36H is the high-level product of this series, which has through-hole shaft. Hollow shaft within diameter Φ8mm can all be customized. Its structural dimensions are as follows. R36H adopts imported waterproof bearings. Its interior is completely sealed, Its protection grade can reach IP67. Signal output is led out by shielded cable, which can effectively avoid electromagnetic interference in the signal transmission process. Its electrical specifications are also available for 0505, 2410, 2405,or 2442.Single output or dual output is optional. Hollow shaft design makes the product directly installed on the shaft of the equipment, saving more space.

WDH35B/WLH35B/R36H series contactless potentiometers give a comprehensive solution to the long-lasting application problems on non-contact potentiometers about 360° effective electrical angle, as well as shaft with front and rear extension or through-hole form from the middle-end, economy, and high-end. We always welcome inquiries and purchases from costomers of tower cranes, limiters, actuators, steering engine feedback and various other industries.
