Male magnetic cable connector:

...Materials:

1.Pogo Pin (Contact):

.Base Material: Brass (good conductivity, formability).

.Plating: 5µ" Min Gold (Au) over 60-100µ" Nickel (Ni).

.Validation: Excellent corrosion resistance (Ni underplate blocks Cu diffusion, Au top layer provides low contact resistance and oxidation resistance). Meets harsh environment requirements. ROHS/REACH compliant.

2.Housing:

.Material: Black HTN +30% Glass Fiber (GF) or LCP. UL94 V-0.

.Validation: High-temperature resistance, excellent dimensional stability (GF), superior chemical resistance (LCP). UL94 V-0 ensures flame retardancy. Critical for safety and severe environments.

3.Magnet:

.Material: NdFeB (Neodymium Iron Boron), Grade N52. Plating: Nickel (Ni).

.Validation: N52 offers the highest magnetic energy product commercially available (strongest pull force). Ni plating provides basic corrosion protection. Note: For extreme salt spray, epoxy coating over Ni is often recommended for NdFeB.

4.Cable & Jacketing:

.Cable: Black OD 3.5mm, 2 Conductors (2C), TC65 (Tinned Copper) 0.08mm stranding.

.Wire Jacket & Connector Jacket: Black TPE (Thermoplastic Elastomer), 90A Shore Hardness.

.Validation: TPE 90A offers excellent flexibility, chemical resistance, and sealing. TC65 wire provides good solderability and corrosion resistance. OD 3.5mm suitable for compact devices.

Mechanical Specifications & Validation
1.Spring Force: 70g ±20g at 1.0mm working stroke.

.Validation: Standard force range for reliable contact. ±20g tolerance is acceptable but monitor consistency in production (affects contact pressure).

2.Stroke:

.Working Stroke: 1.0mm (Normal compressed position during operation).

.Full Stroke: 1.2mm (Maximum compression before damage).

.Validation: Adequate travel for compensation and wear. ~20% overtravel protects the spring.

3.Mechanical Life: 10,000 cycles Min.

.Validation: Standard commercial/industrial rating. Achievable with proper spring design/material (e.g., high-cycle spring steel).

Electrical Specifications & Validation
1.Voltage: 12V DC.

2.Current: 3A.

3.Contact Resistance (PIN): 50mΩ Max (per pin circuit).

.Validation: Resistance is acceptable for 3A @ 12V (Power dissipation = I²R = 9 * 0.05 = 0.45W per pin). Ensure consistent plating and spring force to meet this reliably.

4.Testing: 100% Open and Short Circuit Test.

Validation: Essential quality control to ensure no manufacturing defects.

Female magnetic connector:

..Materials :

. Pins: Lead-free copper alloy C6801
Plating: 5μ" min. Gold over 60–100μ" Nickel (corrosion-resistant)

Housing: Black HTN + 30% Glass Fiber (UL94 V-0 flame-rated)

Shell: Lead-free C6801 with Nickel plating

Magnet: NdFeB N52 grade with Nickel plating (high-strength magnetic field)

....Electrical:

Rated Voltage: 12V DC

Current Capacity: 5.0A

Contact Resistance: ≤50mΩ (per pin)

Validation: 100% open/short circuit tested

....Compliance & Durability

RoHS 3 & REACH compliant

Salt Spray Resistance: 48 hours

....Application Flexibility

PCB Integration: Direct plug-in welding to circuit boards

Cable Assembly: Wire soldering + overmolding encapsulation

Modular Expansion: Transfer terminal support for PCB stacking

Embedded Solutions: Injection molding-ready for custom enclosures

Direct Wire Bonding: Cable-to-connector termination without PCB

Attention:
1.Magnet use NdFeB material, it’s can keep the magnetic force forever (except high temperature,broken,same pole connection)

2.Magnet exist magnetic field interference

3.Can design short-circuit protection

How Magnetic Connectors Work?

.Both sides magnetically connect when placed in proximity to each other
.Light at the back of plug indicates power is flowing
.When the sides are pulled apart, power flow stops immediately
.They avoid short circuits as the connectors repel each other, and if they attract it is on the insulated parts (as both connectors free the same magnetic pole)

Advantages of Magnetic Connector:

1.Effortless User Experience

.Automatic Adsorption: Connects easily with a simple "snap" action – no precise alignment needed.

.Anti-Fall Safety: Detaches cleanly under tension (e.g., tripping on the cable), protecting devices from damage.

2.Exceptional Durability

.High Cycle Life: Rated for 100,000–200,000 connect/disconnect cycles – far exceeding standard connectors.

.Robust Design: Reinforced structure resists physical stress and frequent use.

3.Environmental Resilience

.IPX8 Waterproofing: Device-side (female) port withstands submersion (ideal for wearables, medical gear, outdoor devices).

.Dust Resistance: Sealed design prevents particle ingress.

4.High-Performance Power Delivery

.Fast Charging Support: Handles 5A–10A currents, enabling rapid charging for power-hungry devices.

.Low Resistance: Optimized for efficient high-current transmission with minimal energy loss.

5.Design Flexibility

.Customizable Aesthetics: Shape, color, and branding tailored to match host devices (e.g., wearables, IoT gadgets).

.Form Factor Adaptability: Can be designed for ultra-slim profiles or specialized enclosures.

6.Enhanced Safety

.Anti-Short Circuit: Built-in protection against accidental shorts during connection/misalignment.

.Foolproof Polarity: Physical design prevents incorrect insertion (reverse polarity protection).

7.Advanced Signal Capability

.High-Speed Data: Supports USB 2.0, HDMI 1.3, audio/video signals – replacing traditional ports without compromising function.

.Signal Integrity: Maintains stable transmission for video/audio even with frequent disconnects.
