1. Introduction to IP68 Protection Rating

IP68 is an international standard used to assess the dust and water resistance levels of electronic devices. In an IP68 encoder, IP stands for Ingress Protection rating, where the number 6 indicates the highest level of protection against dust, and the number 8 indicates the highest level of protection against water immersion.

An IP68 waterproof and dustproof encoder means that the encoder has extremely high resistance to water and dust. It can withstand long periods of immersion underwater (typically up to 1 meter depth for 30 minutes) without being affected, and effectively prevents the ingress of dust and large particles.

2. IP68 waterproof and dustproof encoder application scenario

This type of encoder is typically used in environments where operations occur under harsh conditions, such as outdoor equipment, aerospace applications, underwater robots, and more. It’s important to note that while IP68 encoders offer water and dust resistance, they do not completely prevent liquid or dust ingress. Therefore, specific protective measures should still be considered based on actual usage scenarios.

3. IP68 encoder implementation principle

IP68 waterproof and dustproof encoders typically employ special designs and structures to ensure their water and dust resistance capabilities. Here are some possible implementation principles：

(1)For waterproof design: The encoder’s main housing, sealing gaskets, fastening screws, and interfaces are connected using high-density waterproof rubber strips, supplemented with specialized waterproof coatings, effectively preventing liquid ingress.

(2)For dustproof design: The encoder adopts a tightly sealed outer casing that encapsulates internal electronic components, preventing ingress of dust and particles. Additionally, the encoder’s internal circuit boards are designed with high sealing integrity to block entry of external air and dust.

(3)For high-strength and wear-resistant design: Encoders typically utilize high-strength encoding gears and transmission gears to ensure uninterrupted operation over extended periods. Additionally, these gears are often made from wear-resistant materials to enhance the encoder’s lifespan and interference resistance capabilities.

（4）For high-precision design: The encoder also incorporates precise photoelectric sensors, suitable measurement sensitivity, and flexible wiring techniques internally, ensuring high measurement accuracy and interference resistance capabilities.

In summary, the design principles of an IP68 dustproof and waterproof encoder typically revolve around requirements for sealing, dust protection, and high precision. This is achieved through the use of appropriate shielding materials and electronic components.

4. BRT’s innovative IP68 waterproof and dustproof encoder implementation principle

BRT’s dustproof and waterproof encoders incorporate cutting-edge protective technologies, including comprehensive potting and sealing of internal circuitry. This design ensures complete enclosure of electronic components within the encoder, effectively preventing ingress of moisture, dust, and particles.

By employing potting and sealing of the internal circuitry, we can provide a higher level of protection, ensuring the encoder maintains excellent performance even in harsh environments. This sealing design not only prevents moisture ingress but also effectively guards against dust and other impurities, protecting the internal circuits from damage.

In outdoor environments, underwater applications, and other harsh conditions, BRT’s dustproof and waterproof encoders reliably deliver precise measurements and stable performance. You can confidently use our products without worrying about the effects of water and dust.
