5 Must-Have Features in a waterproof motor connector manufacturer

Reliable Waterproof Connectors for Industrial Applications

Ensuring that electromechanical interfaces are safeguarded against moisture is a fundamental requirement in industrial electronics used in automation and process technologies. However, the term ‘waterproof’ can be subjective. Depending on the application, varying levels of resistance to liquids are necessary.

Waterproofing suggests full resistance to humidity—like fog or rain—and submersion in liquids. But from experiences with everyday gadgets like watches or smartphones, we know that protection is often limited. Industrial electrical connectivity requires similar considerations for connectors, which must protect interfaces from liquids for functionality and safety.

Connectors play a key role in maintaining the watertight integrity of electromechanical systems. They must be able to endure multiple plug and unplug cycles while preventing liquid ingress when connected.

The required degree of liquid resistance depends on the application's specifics. For example, connectors in certain automation tasks might not directly contact moisture, whereas others might face splashes or submersion. In hygienic environments, connectors might need to withstand high-pressure cleaning, necessitating specialized designs.

Standardized Labels: Protection Degree and IP Code

Connector manufacturers specify resistance to humidity and liquids in their product data sheets. The protection degree determines the environments where connectors can be used, covered by standards like DIN EN 60529 and ISO 20653. The IP (International Protection) code system represents these degrees, with most connectors' ratings applicable only when mated. Examples include IP67 (temporary immersion) and IP68/69K (permanent immersion or high-pressure exposure). For practical applications, more precise information is preferred to clarify standards like 'temporary' or ‘permanent.’

Lack of knowledge about these standards often leads to misinformation. For instance, a higher IP code (first digit for solids, second for liquids) does not always indicate better protection overall. Additionally, BP codes’ third and fourth positions can include letters denoting specific features, like 'K' for road vehicle equipment in IP69K.

Waterproofing in Industrial Settings

Connectors in industrial contexts must meet electrical parameters like rated current and voltage, along with installation-relevant criteria like design and miniaturization. However, environmental factors such as mechanical loads, high-frequency interference, risk of fire or explosions, and repeated mating cycles significantly influence their design. These factors drive decisions on locking systems, electromagnetic shielding, and contact materials.

A standard requirement is that connectors prevent particle and liquid ingress. Specific protection needs vary across industries, like factory automation, food and beverage, or medical fields, each imposing distinct waterproof standards due to their unique challenges, like frequent high-pressure cleaning in medical and food sectors.

Product Examples: IP67, IP68, and IP69K Standards

M12 connectors from binder meet IP67 standards, and many also comply with IP68/69K. There are corrosion-resistant versions, and higher ratings ensure performance even in harsh outdoor conditions or with aggressive cleaning. For example, IP67 connectors can handle occasional humidity without demanding conditions, while IP68 and IP69K withstand greater depths, high-pressure jets, and aggressive cleaners.

Products like binder NCC series 770 offer added features such as a plastic cover to protect against accidental touch and splash water. Others like the miniature 620 and 720 series also ensure durability through features like O-rings and seals, making them suitable for medical equipment and industrial applications.

Concluding Thoughts: Application-Specific Protection

Protecting electromechanical interfaces from liquids is vital in various industries, with the necessary protection degree always tied to the specific application environment. Product documentation specifies IP codes representing these degrees. binder's connector portfolio, ranging from IP40 to IP68/69K, addresses diverse needs in automation, construction, agriculture, food, and medical technology.

Common Queries on Waterproof Motor Connectors

Here are some frequently asked questions to help you understand the essentials of waterproof motor connectors:

Q1: What does the IP Code mean for waterproof connectors?

The IP Code, or International Protection Rating, indicates the degree of protection offered by connectors against dust and water ingress. It comprises two digits, where the first indicates solid particle protection and the second indicates moisture resistance.

Q2: Why is it crucial for waterproof connectors to withstand multiple mating cycles?

In industrial applications, connectors often need to be connected and disconnected multiple times. The ability to endure these cycles without compromising their waterproof properties ensures reliability and safety over the connector’s lifespan.

Q3: How does exposure to high-pressure cleaning affect waterproof connectors?

High-pressure cleaning is common in industries like Food & Beverage. Waterproof connectors in such environments must be designed to withstand high-pressure jets and aggressive cleaning agents without failing.

Q4: What are the specific considerations for connectors in medical applications?

Medical connectors not only need high waterproof ratings but also must meet stringent hygiene standards. They should resist frequent sterilizations and be constructed from materials that don’t support microbial growth.

Q5: Are all waterproof connectors corrosion-resistant?

No, not all waterproof connectors are corrosion-resistant. It's essential to check if the connectors are made from materials like stainless steel or specific plastics that can withstand the corrosive environments they are to be used in.
