TVS07RF-25-4SA 56 Position Circular Connector for Harsh Environment Applications

ElecSuppliers Part Number GuideAug 15, 2026

The TVS07RF-25-4SA is a rugged circular connector designed for applications where a standard commercial connector may not provide enough mechanical and environmental protection.

Its 56 contact configuration gives engineers a relatively high number of electrical connections within a single circular interface. This makes the part particularly useful for equipment that needs to combine power, control and signal connections within one cable assembly.

Why This Connector Stands Out

The main characteristic of TVS07RF-25-4SA is its combination of a circular connector structure and high contact density.

In equipment exposed to vibration or frequent mechanical movement, the connector needs to remain securely mated while maintaining reliable electrical contact.

This makes rugged circular connectors a natural choice for aerospace equipment, military electronics, industrial systems and other demanding applications.

56 Contacts in One Connector

The 56 contact arrangement is an important reason to use this particular model.

Instead of separating multiple signal groups across several connectors, a single high-density connector can accommodate a larger cable harness.

This can simplify equipment wiring and reduce the number of external connection points on an enclosure.

The specific insert arrangement is also important. When replacing TVS07RF-25-4SA, another connector from the same family should not be assumed to have the same contact configuration.

Jam Nut Receptacle

TVS07RF-25-4SA uses a jam nut receptacle configuration.

This type of connector is designed to be installed through an equipment panel and secured in place, making it suitable for applications where the connector needs to become a permanent part of the enclosure.

The result is a cleaner external interface and a mechanically secure connection between the equipment and its cable harness.

Designed for Rugged Equipment

This is not the type of connector normally selected simply because a PCB has limited space.

Its value comes from its suitability for demanding environments.

Depending on the complete connector configuration and application, rugged circular connectors of this type are used where equipment may experience vibration, shock, moisture, temperature changes or other mechanical stresses.

That makes TVS07RF-25-4SA particularly relevant to equipment that must continue operating outside a controlled office or laboratory environment.

Typical Applications

TVS07RF-25-4SA can be considered for:

• Aerospace equipment

• Avionics systems

• Military electronics

• Industrial control equipment

• Marine equipment

• Rugged instrumentation

• High reliability cable assemblies

The exact suitability depends on the environmental and electrical requirements of the finished product.

Cable Harness Integration

The connector format is also useful when a product relies heavily on cable assemblies.

A multi-contact circular connector allows numerous circuits to enter or leave an enclosure through one mechanical interface.

For equipment manufacturers, this can simplify installation and maintenance because an entire group of connections can be disconnected as one assembly.

This is particularly useful when modules need to be removed for servicing.

Selecting a Replacement

A replacement for TVS07RF-25-4SA needs to match both the electrical and mechanical characteristics.

Engineers should check:

• Contact count

• Insert arrangement

• Shell size

• Connector gender

• Mounting configuration

• Contact type

• Keying and orientation

• Environmental requirements

A connector that has the same number of contacts but a different insert arrangement may not mate with the existing plug.

Why the Complete MPN Matters

Searching only for "56 pin circular connector" is unlikely to produce the exact component required.

The TVS07RF-25-4SA part number identifies a specific connector configuration. This is especially important when maintaining an existing product because even a small difference in shell or insert configuration can make a replacement unusable.

For production purchasing, the complete MPN should therefore remain in the BOM.

TVS07RF-25-4SA Supplier Search

For procurement, use TVS07RF-25-4SA as the primary search term.

When comparing suppliers, confirm the exact part number, manufacturer, connector configuration, contact arrangement and product availability.

For rugged equipment requiring a 56 contact circular connector with a secure panel mounted interface, TVS07RF-25-4SA is a specialized component worth evaluating when its complete specifications match the application.
