M8 3 Pin Extended Threaded Male Female Circular Connector

The M8-3P Extended Threaded Circular Connector is a three-contact electrical connector pair with a black housing and a threaded mating structure. It consists of an elongated male connector body with external threads and a matching female connector featuring a larger coupling housing.

Unlike a plain cylindrical plug, this model incorporates a threaded section directly into the connector body. The extended front profile provides space for the mating interface and threaded connection arrangement.

The matching female component has a ribbed outer surface and a recessed three-position socket interface.

Extended External Thread Design

The male connector features an extended threaded section positioned in front of a hexagonal housing shoulder.

The external threads form the mechanical connection interface for the matching female coupling component. This configuration is intended for applications where a screw-type mating arrangement is required.

The hexagonal section provides a defined flat-sided area that can assist with positioning during installation.

Thread dimensions, engagement depth and recommended tightening requirements should be confirmed from the corresponding technical drawing.

Integrated Male Connector Structure

The male component combines several mechanical features within one connector body.

Its rear section has a narrower cylindrical profile, followed by a hexagonal shoulder and an extended threaded front section.

Inside the circular opening are three metallic contact pins. These contacts are recessed within the housing rather than extending beyond the front rim.

The integrated housing profile distinguishes this version from standard M8 connectors with shorter or non-threaded mating structures.

Female Coupling Connector Configuration

The female component has a wider cylindrical body with longitudinal raised ribs around its outer surface.

The ribbed profile provides a textured gripping area for handling the coupling component during assembly.

Its front interface contains three socket openings positioned within a projecting central section. The surrounding housing forms part of the coupling structure.

The female connector must be matched with the corresponding threaded male component to ensure correct mechanical engagement and contact alignment.

Three-Pin Electrical Connection

The M8-3P connector uses three electrical contact positions.

Each contact can be assigned according to the intended circuit configuration. The three-position interface allows multiple conductors to pass through one connector assembly.

The electrical functions of the contacts depend on the equipment wiring design. Before installation, verify the pin numbering and conductor assignments against the product specification.

Rated voltage, rated current and contact resistance must also be checked before selecting the connector for an electrical circuit.

Equipment Connection Applications

The M8 3 Pin Extended Threaded Connector can be considered for electrical assemblies requiring a three-contact threaded connection.

Control Equipment Interfaces

The connector may be incorporated into compatible control equipment that requires a detachable three-conductor interface.

Electrical Panel Connections

Its threaded housing design may be suitable for panel-related connection arrangements when the mounting dimensions and installation requirements are compatible.

Industrial Wiring Assemblies

The three-contact configuration can accommodate suitable industrial wiring circuits within the connector's verified electrical ratings.

Equipment Module Connections

The matching male and female components allow compatible modules to be connected through a removable threaded interface.

Thread Engagement and Assembly Procedure

Before connecting the male and female components, confirm that both parts have matching thread dimensions and contact arrangements.

Align the mating interfaces before engaging the coupling housing. The threaded components should rotate smoothly without excessive resistance.

Avoid cross-threading or applying excessive tightening force, as this may damage the housing or interfere with proper electrical contact engagement.

After assembly, inspect the coupling interface to confirm that the threaded connection is correctly seated.

Selection Requirements for Threaded Connectors

When selecting this M8-3P connector, the threaded structure must be evaluated alongside its electrical characteristics.

Important selection factors include the external thread dimensions, mating depth, installation clearance and rear terminal configuration.

The connector's overall length should be checked carefully because the extended male body may require more installation space than a standard short-body connector.

For applications exposed to vibration, dust or moisture, the appropriate mechanical retention and environmental protection specifications should be confirmed before use.

Frequently Asked Questions (FAQ)

Q1: What makes this M8-3P connector different from a standard M8-3P connector?

This version features an extended male housing with an external threaded section and a matching female coupling connector.

Q2: How many electrical contacts does the connector have?

The M8-3P has three electrical contact positions.

Q3: What is the purpose of the external threaded section?

The external thread forms the mechanical mating interface with the corresponding female coupling component.

Q4: Does the male connector have a hexagonal section?

Yes. The male connector includes a hexagonal housing shoulder behind the threaded section.

Q5: What type of housing does the female connector have?

The female component features a black cylindrical coupling housing with raised ribs around its exterior.

Q6: Can this connector be used for panel installation?

It may be considered for compatible panel assemblies, but the actual mounting dimensions and required installation hardware must be verified.

Q7: Is the threaded M8-3P connector waterproof?

Waterproof performance cannot be confirmed from the image alone. Any IP protection rating must be verified using the manufacturer's technical specifications.

Q8: What information should be checked before ordering?

Confirm the M8-3P model, thread dimensions, contact arrangement, overall length, mounting requirements, terminal type, rated voltage and rated current.
