IP67 connectors 104 pin

High-density D-type 104 Pin D Sub Ip67 Connector.

In modern high-tech fields such as industry, military, and aerospace, electronic devices are becoming increasingly complex, demanding stringent requirements for the density and reliability of signal transmission. High-density waterproof d sub connector have become indispensable interconnect components in these critical applications due to their exceptional performance in integrating a large number of contacts within limited space and maintaining stability in harsh environments. This article will provide a detailed overview of their core specifications, protective features, and application scenarios.

Core specifications and high-density design.

The most striking feature of the high-density ip67 d sub connector is its extreme utilization of space. Compared to traditional standard D-Sub connectors, it significantly increases the number of contacts without increasing the size of the housing. Among these, the 104 Pin D Sub Connector is the flagship model of the series, with the following specific parameters:

Number and layout of contact points: This 104 Pin D Sub Female connector features 104 signal contact points, meticulously arranged in 5 rows, effectively increasing the signal transmission density per unit area.

Enclosure dimensions: Its enclosure adheres to the industry-standard layout specification 6 (Shell Size 6). This means it can achieve mechanical compatibility with other D-Sub products of the same size, facilitating upgrades and replacements for existing systems.

Electrical performance: These connectors typically support a rated current of up to 5A, with contact resistances as low as 20 milliohms or less and insulation resistances exceeding 5000 megohms, ensuring the integrity and stability of the signals.

Materials and Manufacturing: To ensure long-term reliability, the pins are often made of copper alloys and undergo full gold plating to enhance corrosion resistance and electrical conductivity. The outer casing is typically made of steel and coated with a yellow chromate or cadmium layer, providing excellent mechanical strength.

Robust protection and environmental adaptability.

“Water resistance” is another significant core value of this type of connector, enabling it to function properly in adverse conditions such as liquids, dust, and other unfavorable factors. The level of protection varies depending on the specific product series, as follows:

Protection Classes IP67 and IP68: Many high-density D-Sub connectors meet the IP67 or IP68 protection standards. IP67 indicates that the connector is fully resistant to dust ingress and can be submerged in water up to 1 meter deep for up to 30 minutes without sustaining damage. IP68 provides even more stringent protection against continuous submersion.

Wide operating temperature range: To accommodate various extreme environments worldwide, these connectors typically have a very broad operating temperature range. Common operating temperature ranges are from –55°C to +125°C, or even broader, to meet the needs of applications ranging from extremely cold regions to high-temperature industrial sites.

Electromagnetic Interference (EMI) Shielding: The metal casing design not only provides physical protection but also effectively shields against electromagnetic interference (EMI) and radio-frequency interference (RFI), ensuring the accuracy of data transmission in high-noise environments.
