3 Aspects To Notice When Choosing Sealed Connectors
3 Aspects To Notice When Choosing Sealed Connectors
In the previous article, we discussed the concept of sealed and hermetically sealed connectors, as well as solutions for anti-oxidation and anti-corrosion connectors (Read More >> Click Here).
This explanation helps engineers and procurement professionals understand why they choose “Sealed Connectors” to prevent oxidation or corrosion caused by moisture, gases, or oil contamination, while ensuring uninterrupted signal transmission. However, even when selecting sealed connectors, there are still critical factors to consider. Today, we will reveal and analyze these essential points.
1. Potential Risks After Disconnecting Sealed Connectors
Most sealed connectors are used in pairs. Once disconnected, they may no longer provide the original protection and could further degrade the connector interface's performance, defeating the purpose of choosing sealed connectors in the first place.
Even if the connector remains sealed after disconnection, there is a high potential risk of contact damage. Specifically, whether the waterproof function can be maintained is uncertain. Such issues could lead to significant cost losses.
CHIN NAN Precision Electronics offers the following reminders:
- Engineers and procurement professionals should select “matched” connectors to ensure proper functionality.
- Vibrations during product transportation or operation could lead to disconnection, necessitating rigorous testing or selecting connectors with superior sealing materials and designs.

These recommendations help ensure the optimal operation of sealed connectors while reducing potential damage and cost risks.
2. Material Selection for Sealed Connectors
Many procurement professionals and engineers believe that choosing sealed connectors with robust stainless steel housings, known for their anti-corrosion and anti-contamination properties, is always better for their products.
While this sounds appealing, it’s not suitable for all industries. For instance, in the transportation sector, vehicle weight limits are a significant factor.
Increased weight demands more fuel and energy, leading to higher costs. Therefore, lightweight materials are a crucial consideration when selecting sealed connectors.
Additionally, durability and cost are key factors. Based on application scenarios and customer requirements, CHIN NAN Precision Electronics offers the best solutions and consultation to fully meet your needs.
3. Interface Selection and Industry Applications for Sealed Connectors
Sealed connectors are designed to protect equipment from liquid or gas ingress, thereby preventing oxidation and corrosion and ensuring stable and reliable signal transmission. As a result, sealed connectors are ideal for outdoor and harsh environments, such as:
- Humid and rainy environments: Preventing water or other liquids from seeping in, which could damage or corrode connectors.
- Dusty environments: Blocking dust ingress that may cause poor contact or signal interference.
- Corrosive environments: Resisting acids, alkalis, and salt corrosion.
Beyond waterproof and hermetically sealed connectors, some sealed coaxial connectors feature oil-resistant capabilities for specific environments, such as:
-
Petroleum and natural gas industries
-
Food industries
-
Chemical industries
In these scenarios, oil resistance becomes a critical consideration.
Sealed connectors can also be categorized into four types based on sealing location:
- Internal Sealing: Prevents liquid or gas ingress from inside the connector.
- Panel Sealing: Prevents external ingress from the connector's panel.
- Mating Sealing: Prevents ingress at the connector's mating interface.
- Comprehensive Sealing: Provides complete sealing at all locations, ensuring maximum protection.
CHIN NAN recommends the following sealed connector types:
- BNC Interface Connectors: 50Ω (frequency up to 4 GHz), 75Ω (frequency up to 1 GHz). Widely used in computer networks, audio, data processing equipment, and telecom devices.
- N-Type Connectors: 50Ω (frequency up to 11 GHz), 75Ω (frequency up to 1.5 GHz). Commonly applied in aerospace, broadcasting, audio, and video industries.
- SMA Connectors: Frequency range up to 12.4 GHz (with flexible cables) or 18 GHz (with semi-rigid cables). Often used in circuit boards, microwave components, and RF modules.
- TNC Interface Connectors: 50Ω (frequency up to 11 GHz), 75Ω (frequency up to 1 GHz). Suitable for aviation, data transmission, medical equipment, mobile communication devices, test equipment, and microwave components.
