The M8 3 Pin Threaded Male Female Circular Connector is a black electrical connector assembly consisting of a threaded male plug and a corresponding female socket. The male component has an externally threaded cylindrical section with three metal pins positioned inside the front opening. The female component uses a larger coupling body surrounding a three-position socket interface.
The integrated screw connection allows the two connector halves to be joined through their corresponding threaded structures. This version has a relatively short threaded male body, distinguishing it from extended-thread connector designs.
The male plug incorporates an external threaded section directly into its cylindrical housing. A wider circular shoulder separates the threaded front from the narrower rear body.
Three metallic pins are arranged inside the recessed mating cavity. The surrounding rim helps keep the contact tips within the front profile of the connector.
The threaded portion is intended to engage with a compatible female coupling assembly. Its pitch, diameter and engagement length must match the corresponding socket component.
The female connector features a broad circular housing with raised gripping sections around its outer circumference.
The socket interface is positioned inside the coupling body, with three contact openings arranged on the front face. The surrounding collar provides the structure used to engage the matching threaded plug.
The raised exterior sections offer defined surfaces for handling the connector when tightening or releasing the coupling.
The internal socket geometry and thread engagement must correspond to the male connector to achieve correct assembly.
The screw-type mating arrangement is an important feature of this M8-3P version.
Unlike connectors that rely solely on a push-fit interface, this design uses complementary threaded components to secure the mating pair mechanically.
During connection, the plug and socket should first be positioned so that the electrical contacts align. The coupling can then be engaged according to the connector's specified assembly procedure.
Correct thread engagement helps maintain the intended assembled position. Mechanical retention performance depends on the connector's verified design and operating conditions.
The connector contains three separate electrical contact positions within its circular interface.
Each contact position can be assigned to an electrical conductor according to the required circuit configuration. The interface may accommodate compatible power, control or signal connections when the specified electrical ratings permit.
The recessed male contact arrangement and matching female sockets establish the electrical connection when the connector halves are fully mated.
Contact numbering should be confirmed using the technical drawing before wiring or connecting the terminals to a circuit board.
The visible connector structure includes the following details:
Model: M8-3P Threaded Type
Connector Configuration: Male and Female
Contact Positions: 3
Housing Color: Black
Male Interface: Recessed metallic pins
Female Interface: Three socket openings
Male Housing: Cylindrical body with external threads
Female Housing: Circular coupling collar with raised gripping sections
Mechanical Connection: Screw-type mating structure
Rear Connection: Metallic terminals visible on the connector assembly
The M8-3P threaded connector can be considered for electrical equipment requiring a three-contact detachable interface.
Electrical Control Components
The three-position layout may be used for compatible control circuits where an electrical connection must be established between separate equipment sections.
Equipment Panel Interfaces
The threaded male housing can be evaluated for panel-related designs when the mounting dimensions, installation clearance and required hardware correspond to the connector specification.
Signal Connection Assemblies
The connector may accommodate suitable three-conductor signal connections where the required electrical performance falls within the specified operating limits.
Modular Electrical Equipment
Its mating plug-and-socket structure permits compatible electrical sections to be connected and separated during equipment assembly or maintenance.
The threaded connector structure requires consideration of both mating dimensions and installation clearance.
The external thread must match the female coupling mechanism. Sufficient space should be provided around the coupling housing to permit assembly and removal.
The rear terminal projection and cable or board connection arrangement also influence the overall installation envelope.
For equipment with closely positioned components, dimensional drawings should be reviewed before selecting this connector.
Before use, the connector should be checked against the electrical operating requirements of the intended circuit.
Rated current, operating voltage, insulation resistance and contact resistance should be obtained from the applicable technical specification.
Where the connector is exposed to vibration, moisture or temperature variation, the documented mechanical and environmental performance should also be evaluated.
A threaded connection alone does not establish a waterproof or vibration-resistance rating.
Q1: What type of connection does the M8-3P threaded connector use?
It uses a screw-type mating arrangement consisting of an externally threaded male plug and a corresponding female coupling component.
Q2: How many electrical contacts are provided?
The connector has three contact positions.
Q3: What is the difference between this model and the M8-3P extended threaded version?
This model has a shorter male threaded body. The extended version features a longer threaded section and a different housing profile. Exact dimensions should be compared using the relevant product drawings.
Q4: Does the female connector have a gripping structure?
Yes. The female housing has raised sections around its outer circumference that provide defined surfaces for handling the coupling.
Q5: Can this connector be used for control or signal circuits?
It may be used for compatible control or signal connections when its electrical ratings and contact assignments satisfy the circuit requirements.
Q6: Does the threaded design mean the connector is waterproof?
No. The presence of a threaded coupling does not establish waterproof performance. Any IP protection rating must be confirmed from the product datasheet.
Q7: Can this M8-3P connector be connected to any three-pin M8 socket?
Not necessarily. The thread dimensions, mating geometry, contact arrangement and electrical specifications must be compatible.
Q8: What information should be checked before ordering?
Confirm the M8-3P threaded model, male and female configuration, thread dimensions, contact layout, terminal type, rated current, rated voltage and installation requirements.
