● Pitch and Range

The 2mm pitch of these connectors ensures accurate and reliable connections. The series is available in a wide range of configurations, ranging from 2 to 96 ways, making it appropriate for a wide range of applications, from simple to complicated.

● Contact Options

The connections have replaceable contacts that can be gold or tin plated. Contacts plated in gold have a high purity and a firm acid gold surface, ensuring outstanding electrical performance.

● Application Diversity

M80-5400642 connectors are used as low voltage connectors in high packing density electronic devices. They are adaptable enough to be used in board-to-board, cable-to-board, and cable-to-cable connections, making them an excellent choice for a wide range of electronic systems.

● Polarization and Latching

The polarization of these connectors helps to avoid incorrect pairing and makes for more reliable connections. They can also be constructed with a latching function (known as L-Tek) or in a jackscrew type (known as J-Tek), allowing for greater freedom in both design and application.

● MixTek Options

The series also offers mixed technology (MixTek) connectors for added versatility. These connectors have jackscrews and a choice of power or coax contacts, increasing their utility in a variety of applications.

● Quality Standards

Some connector styles in the series are manufactured and tested in accordance with BS9525 F0033 standards, ensuring strict quality and performance parameters. All connections in the line are built to the same exacting standards.

● Cable Assemblies

In addition to individual connectors, the M80-5400642 series provides pre-cabled contacts and cable assemblies in a variety of combinations, making it easy to meet complex wiring needs.

Electrical Characteristics of M80-5400642 Connectors

Understanding the electrical characteristics of connectors is critical when selecting them for your electronic applications. The M80-5400642 connectors have a number of unique electrical properties that set them apart from other connecting alternatives. Let’s take a deeper look at these features:

Impedance – Maintaining Signal Integrity

● Impedance: 50Ω

The M80-5400642 connectors have an impedance of 50, which is critical for signal integrity in high-frequency applications. This impedance value guarantees that the connections’ characteristic impedance matches that of the associated cables or components, eliminating signal loss and reflections.

Frequency Range – Broad Compatibility

● Frequency Range: Up to 6GHz (Dependent on cable type or board layout)

These connectors have a frequency range of up to 6GHz. However, real frequency performance may vary depending on the cable type or board layout employed. Because of their versatility, they can be used in a wide range of applications, from standard to high-frequency designs.

VSWR – Ensuring Minimal Signal Reflection

VSWR (Voltage Standing Wave Ratio):

  • M80-310: 1.19 + (0.04 x Frequency) GHz max
  • Others: 1.05 + (0.04 x Frequency) GHz max

The Voltage Standing Wave Ratio (VSWR) is an important measure to consider when evaluating signal quality. The M80-5400642 connectors have low VSWR values, which provide minimal signal reflection and great transmission efficiency across a wide range of frequencies. This property is extremely significant in RF and microwave applications to retain signal quality.

Voltage Ratings – Handling Electrical Stress

● Voltage Rating (at 1,013mbar, sea level): 180V AC at 500mA

These connectors are excellent for a wide range of electrical applications since they can manage a maximum voltage of 180V AC at 500mA. The voltage rating ensures that the connectors can resist the electrical stress that is common in electronic circuits.

Voltage Proof – Assuring Reliability

● Voltage Proof (at 1,013mbar, sea level): 1,000V ACrms

The voltage proof rating of 1,000V ACrms attests to the durability of these connectors. This characteristic ensures its dependability and safety in high-voltage conditions, giving engineers and designers peace of mind while working on a variety of projects.

Contact Resistance – Minimizing Energy Loss

● Contact Resistance: 6mΩ max

Low contact resistance is required to reduce energy loss and maintain effective electrical connections. The contact resistance of the M80-5400642 connectors is no more than 6m, guaranteeing that your electrical impulses pass through with minimal loss.

Insulation Resistance – Preventing Leakage

● Insulation Resistance (at 250V rms): 106 MΩ

For the purpose of minimizing electrical leakage and ensuring that conducting elements within connectors are segregated, high insulation resistance is an essential component. With an insulating resistance of 106 M, these connections offer excellent protection against electrical interference.

Lastly, the M80-5400642 connectors feature a varied set of electrical qualities, which makes them appropriate for a wide variety of uses in the electronic industry. Whether you’re working with high-frequency signals or high voltage, or you just need reliable and efficient connections, these connectors give you the performance and quality you need to succeed in your electrical design projects.


In conclusion, the M80-5400642 connectors stand as a pinnacle of versatility and reliability in the realm of electronic interconnectivity. With an extensive array of options and termination methods designed to meet the multifaceted demands of engineers and manufacturers within the electronics industry, they emerge as the optimal choice.
