DC/Earphone Jack
DC Jack Connectors provide stable power input for electronic devices, supporting current specifications from 1A to 5A. The 3.5mm Earphone Jacks are suitable for audio signal transmission in consumer electronics and automotive applications. Both types of connectors emphasize signal transmission stability and mechanical durability. They are widely used in power interfaces for various electronic devices, primarily serving fields such as network communications, security monitoring, medical electronics, industrial control, and consumer electronics.
M&T is an experienced DC Jack Connector Manufacturer and Earphone Jack Connector Manufacturer, supplying reliable power input and audio interface solutions for OEM electronics projects. Our product range includes DC power jacks and 2.6mm/3.5mm audio jack connectors in multiple pin counts, mounting styles, orientations, and PCB configurations.
Designed for stable electrical contact and mechanical durability, M&T DC and audio jacks are used in consumer electronics, communication equipment, security systems, medical electronics, industrial control equipment, automotive electronics, and other electronic devices.
As part of M&T's broader Electrical Connector portfolio, standard models and project-specific connector solutions are available for prototype development and volume production.
M&T DC Jack Connectors, also referred to as DC power jack connectors, provide a compact interface for supplying DC power to electronic devices. Different models are available according to plug dimensions, pin configuration, rated current and voltage, PCB layout, mounting method, and installation orientation.
Our DC jack range includes various:
Pin and terminal configurations
SMT and through-hole/DIP mounting options
Vertical and right-angle PCB structures
Plug and mating dimensions
Current and voltage ratings
Housing and terminal structures
Rather than using one electrical rating across the complete range, specifications vary by model so engineers can select a DC Power Jack Connector according to the actual power and PCB requirements of their device.
M&T supplies 3.5mm Earphone Jack Connectors and audio jack connectors for analog audio signal interfaces in electronic equipment. Our portfolio includes multiple contact counts, PCB mounting methods, connector orientations, and mechanical configurations for different device designs.
In addition to 3.5mm models, selected Audio Jack Connectors are available in other interface sizes, including 2.6mm configurations.
SMT Audio Jacks support surface-mount PCB assembly and are suitable for compact electronic designs where PCB space and automated production are important considerations.
Through-hole and DIP Earphone Jack Connectors provide secure mechanical attachment to the PCB and are available in different pin counts and orientations according to the product design.
Different PCB layouts require different insertion directions. Right-angle and vertical configurations allow engineers to coordinate the audio interface with enclosure design, PCB positioning, and external device access.
Connector selection should be based on both the electrical interface and the mechanical design of the finished device. Before choosing a DC jack or earphone jack, engineering and purchasing teams should consider:
Interface Size – Match the DC plug or audio plug dimensions required by the device.
Pin Count – Select the appropriate contact configuration for power or audio circuit requirements.
Rated Current & Voltage – Especially important when selecting a DC jack for a power input application.
Mounting Method – Choose SMT or DIP/through-hole according to PCB assembly requirements.
Connector Orientation – Vertical or right-angle according to PCB and enclosure layout.
Contact Resistance – Consider stable electrical or signal transmission requirements.
Insertion & Withdrawal Force – Important for user-operated interfaces and mating reliability.
Mechanical Durability – Evaluate the expected number of mating cycles for the end application.
Operating Temperature – Match connector specifications to the equipment's working environment.
M&T provides model-specific technical specifications so customers can compare suitable connectors before sampling and mass production.
A standard connector may not always fit an existing PCB footprint, enclosure opening, mating plug, or product architecture. M&T supports Custom DC Jack Connectors and audio jack solutions according to customer drawings, samples, or technical requirements.
Depending on the project, customization can involve connector dimensions, pin arrangement, terminal configuration, PCB mounting structure, insertion direction, housing design, contact materials, plating, and other mechanical or electrical requirements.
M&T integrates mold design and processing, connector development, production, and automated manufacturing. This enables our engineering and production teams to support customers from connector evaluation and sample development through volume supply.
