DUAL-HEAD 2 PIN MAGNETIC POWER CABLE

Engineering Summary

This dual-head magnetic power cable assembly uses two round 2-pin magnetic output heads connected through a branched cable structure. The reference configuration is intended for LED power applications requiring two detachable magnetic power interfaces from one cable assembly.

Each round magnetic head provides a project-defined 2-pin electrical interface. The exact polarity, input voltage, current per branch, total trunk current, cable lengths, wire gauges and device-side mating structure should be defined according to the approved project drawing.

Magnets primarily assist capture and retention at each output head. Final position, alignment and electrical seating should be established by the round mating geometry and mechanical datums rather than magnetic attraction alone.

Dual-Head Cable Architecture

The visible cable assembly uses one common input section that divides into two cable branches, with one round magnetic power head at the end of each branch.

This architecture should be treated as a complete cable harness rather than as two independent connector parts. The common section, branch junction, individual branch cables and both magnetic heads must be reviewed together.

Output Heads 2 round magnetic heads

Pin Count 2 Pin per head

Cable Structure Common section + two branches

Primary Function LED power delivery

Round 2-Pin Magnetic Interface

Each branch terminates in a compact round magnetic head. The approved drawing should define the two electrical paths, contact geometry, polarity and device-side mating structure.

A central contact and surrounding circular mating structure are visible in the reference configuration, but the exact electrical function of each conductive element should be confirmed from the Pin Map.

Device-Side Mating Interface → To Be Confirmed

Branch Current and Total Input Current

Dual-output power cables require separate definition of the load current at each LED branch and the current carried by the common input section.

If both LED outputs operate simultaneously from one common source:

Itotal = Ibranch 1 + Ibranch 2

The two output heads should not automatically be assumed to carry equal current. Actual branch current depends on the LED loads, cable resistance, termination resistance and magnetic contact interfaces.

The main cable section and branch junction should therefore be sized for the maximum expected combined load, while each branch should be sized for its individual operating condition.

Voltage Drop to Each LED Output

Each magnetic output has its own complete conductive path from the source through the branch cable and magnetic interface to the LED load.

Vdrop1 = I1 × Rpath1
Vdrop2 = I2 × Rpath2

Ploss,total = I1² × Rpath1 + I2² × Rpath2

Branch length, conductor gauge, junction resistance, connector contact resistance and device-side wiring should be included when confirming the voltage available at each LED module.

Two branches that look mechanically similar should not automatically be assumed to have identical electrical resistance without a defined cable drawing and conductor specification.

Common Trunk and Branch Junction

The branch junction is both an electrical and mechanical part of the cable assembly.

The project drawing should define the common cable length, branch lengths, conductor routing, splice or junction architecture, wire gauge, strain relief and cable outlet directions.

If the cable is repeatedly moved, routed around equipment or exposed to pulling loads, branch-junction strain and cable flex requirements should be included in the validation plan.

LED Power Integration

This cable architecture can be evaluated for LED equipment where two removable power interfaces are required from one source-side cable assembly.

The LED system designer should define the required input voltage, current for each output, maximum simultaneous load, allowed voltage drop and thermal limits.

The magnetic cable itself should not be treated as a voltage regulator or current-control device unless dedicated electrical circuitry is explicitly included in the approved assembly.

Magnetic Capture and Release Behavior

Each round magnetic head should be evaluated as an individual mechanical mating interface.

Capture force, retention force, axial separation force and peel force describe different conditions and should be specified separately where relevant.

A force value measured on one magnetic head should not automatically be multiplied by two to describe the complete cable assembly.

Final position and contact seating should be controlled by the mating geometry. Stronger magnetic retention is not automatically better for the LED system.

Contact Compliance and Mechanical Stop

The internal contact structure cannot be fully confirmed from the product image alone.

If a spring-loaded contact is used, working stroke, total travel, spring force and installed compression should be defined separately by the approved contact drawing.

Working stroke represents the intended operating compression and should not be confused with total travel.

The connector housing should define the final mechanical seated position. Spring-loaded contacts should provide electrical connection and controlled Z-axis compliance rather than serve as the primary structural stop.

FAQ

What is a dual-head 2 pin magnetic power cable?

It is a branched cable assembly with two separate round magnetic output heads. Each head provides a project-defined 2-pin power interface.

Does two 2-pin heads mean this is a 4-pin connector?

No. The assembly contains two separate 2-pin mating interfaces rather than one 4-pin connector.

Can both LED outputs operate at the same time?

Simultaneous operation can be designed for the project, but the source, common trunk, branch junction, wire gauges and magnetic interfaces must be sized for the total expected load.

How is total cable current calculated?

When both branches share one source, total current is the sum of the active branch currents. The two branch currents do not need to be identical.

Can the two LED branches have different lengths?

Yes. Branch lengths can be customized, but conductor resistance and resulting voltage drop should be reviewed separately for each LED output.

What current can each magnetic head support?

Current capability is project-specific and must be validated through the complete conductive path, including the cable conductor, branch junction, termination, magnetic contact interface and LED-side connection.

Are the round contacts spring-loaded pogo pins?

The visible mating interface does not fully establish the internal contact mechanism. Spring-loaded construction, working stroke and total travel should be confirmed by the approved contact drawing.

Does stronger magnetic force improve the LED power connection?

Not automatically. Magnets primarily provide capture and retention. Electrical performance depends on the complete conductive path and mating condition, while final seating is controlled by the mechanical interface.

Can the source-side termination be customized?

Yes. The source-side termination can be defined according to the LED power system, cable construction and equipment integration requirements.

What information is required for a custom dual-head LED magnetic cable?

Provide the 2-pin Pin Map, LED operating voltage, current per branch, simultaneous-load condition, main and branch cable lengths, wire gauges, source-side termination, mating dimensions and available device drawings.
