Features, Advantages and Applications of Bedook Teflon Proximity Switch

The Bedook Teflon proximity switch belongs to the inductive proximity sensor. It innovatively adopts copper-plated Teflon as the shell material and PTFE as the sensing surface material. Compared with traditional inductive proximity sensors, its ability to resist the erosion of various chemical substances such as acids, alkalis and salts has been significantly enhanced. At the same time, it can better withstand environments with high voltage, high frequency and high temperature, reduce the risks of strong magnetic interference, electrical interference and leakage, and especially be able to resist harsh conditions such as welding spatter, accurately detecting welding fixtures, metal parts, etc. Once the product was launched, it was recognized and trusted by customers.

Features of Bedook Teflon Proximity Switch

Excellent performance of copper-plated Teflon shell

Resistance to welding slag accumulation

In welding and other working conditions, the copper-plated Teflon shell of the Bedook Teflon proximity switch effectively resists the adhesion and spatter of welding slag. Once the welding slag splashes onto the Teflon coating, it immediately falls off, avoiding the accumulation of welding slag on the sensor surface. Thus, the internal circuit is protected from damage, and the sensing failure caused by the accumulation of welding slag is prevented. It is especially suitable for places with frequent welding operations such as automotive welding workshops.

Excellent corrosion resistance

Teflon has strong chemical stability and is hardly eroded by chemical substances such as acids, alkalis and salts. Therefore, the Bedook Teflon proximity switch can work stably for a long time in harsh chemical environments, such as in the fields of chemical industry, food processing and ocean, effectively extending the service life of the equipment.

Good high-temperature resistance

The high-temperature resistance performance of the Teflon coating is outstanding. The maximum working temperature can reach 290°C, and the intermittent working temperature can even reach 315°C. This enables the Bedook Teflon proximity switch to maintain stable performance in high-temperature environments and is not prone to deformation and aging. It can be applied in scenarios with high-temperature requirements such as automotive welding workshops.

Outstanding non-stickiness and self-cleaning property

The surface energy of Teflon is extremely low and has extremely strong non-stickiness. Very few solid substances can permanently stick to its surface. Dust, oil stains and other impurities are not easy to adhere. Even if there is a small amount of adhesion, it is also easy to clean. In some harsh industrial or outdoor environments, it can effectively reduce the impact of pollutant accumulation on equipment performance and reduce maintenance costs and frequencies.

Advantages of Bedook Teflon Proximity Switch

Resistance to welding slag accumulation

The Bedook Teflon proximity switch shows extremely strong resistance to welding slag accumulation thanks to its unique shell material of copper-plated Teflon and sensing surface material of PTFE. The extremely low surface energy of Teflon makes it difficult for welding slag to adhere to it. Its smooth surface further reduces the adhesion force of welding slag, and the excellent chemical stability of Teflon ensures that no chemical reaction and adhesion occur even when in contact with welding slag.

The excellent high-temperature resistance enables the Bedook Teflon inductive proximity sensor to maintain stable physical and chemical properties of the shell and sensing surface in the high-temperature environment generated by welding, and will not deform or decompose due to high temperature. Thus, welding slag cannot stably exist on its surface, effectively preventing the accumulation of welding slag and ensuring the reliable operation and long-term durability of the proximity switch in harsh working conditions such as welding.

Resistance to strong magnetic field interference

The Bedook Teflon proximity switch performs outstandingly in resisting strong magnetic field interference. Its interior adopts a unique design with patented technology, enabling the sensor to effectively block the invasion of external magnetic fields when facing strong magnetic field environments and avoid interference to its internal sensing elements and circuits. Whether near strong magnetic equipment such as large motors and transformers commonly found in industrial production or in other environments with complex electromagnetic fields, this type of sensor can work stably and accurately detect the proximity of metal objects, always maintaining reliable switch signal output.

Stronger environmental adaptability

The copper-plated nickel shell of ordinary inductive switches is prone to corrosion and damage in harsh environments such as chemical industry, food processing and ocean, while the Bedook Teflon proximity switch can better adapt to these harsh environments and effectively resist the influence of various corrosive substances and harsh climate conditions to ensure long-term stable operation and reduce the risk of failure and maintenance costs caused by environmental factors.

High-precision detection and rapid response

Due to the material advantages of the PTFE sensing surface and the feature of no attenuation in all-metal detection, the Bedook Teflon proximity switch performs more outstandingly in terms of detection accuracy and stability. Whether in static or dynamic detection, it can more accurately sense the proximity and position changes of metal objects and output more reliable switch signals, thereby providing more accurate position feedback for industrial automation control systems. It is suitable for occasions with extremely high requirements for detection accuracy, such as aerospace and automotive manufacturing fields.

Higher safety

The good insulation performance and corrosion resistance of the B Teflon inductive proximity sensor enable it to effectively prevent safety accidents such as leakage and short circuit when used in dangerous environments with flammable and explosive substances or high humidity. In addition, its non-contact detection method avoids sparks that may be generated by mechanical contact, further improving the overall safety of the system. It can be widely used in industries with strict safety requirements such as chemical industry, petroleum and natural gas.
