Micro Electrical Connectors

T1251: 1.25mm Pitch Micro Electrical Connectors

The T1251 series are 1.25mm pitch through-hole micro connectors, designed for high-density PCB layouts with stable electrical performance and broad compatibility.

• Small Pitch & High Integration: 1.25mm narrow pitch supports 2 to 16 pins, enabling compact multi-circuit connections.

• Dual Mounting Options: Straight-through (T1251A) and right-angle (T1251AW) types, compatible with wave soldering processes.

• Electrical Performance: Suitable for low-power signal and current transmission; flame-retardant materials ensure safety and durability.

• Compatibility: Fully compatible with mainstream brand interfaces of the same specification, reducing adaptation costs.

Application Scenarios

1. Consumer Electronics

Suitable for TWS earphone charging cases, smart wearables, mini power banks, etc.

Right-angle type saves vertical space for thin designs; straight-through type supports multi-circuit vertical transmission, ensuring stable signals and current.

2. Industrial Control

Ideal for miniature sensors, PLC expansion units, and industrial automation modules.

Through-hole soldering ensures secure connection; wide temperature range adapts to workshop variations, guaranteeing stable low-power signal transmission.

3. Smart Home

Suitable for smart door locks, environmental sensors, and lighting driver modules.

Small pitch maximizes space utilization; flame-retardant material meets safety standards and ecosystem compatibility.

4. Medical Equipment

Meets the requirements of portable pulse oximeters and miniature medical sensors.

Compact design saves space; stable electrical performance ensures accurate physiological data transmission.

• Dual-branch parallel process: Copper strips are stamped and electroplated to form terminals; injection molding materials are processed into flame-retardant housings and components.
• Assembly & Inspection: Pin assembly, CCD visual inspection, automated taping, and full-process final inspection.
• Qualified products are stored and shipped per order, ensuring consistency and reliability.

• Packaging: Inner packaging is anti-static, dustproof, and shockproof. Outer packaging uses high-strength corrugated boxes with cushioning, secured on standard pallets.
• Storage: Maintain original packaging in a clean, dry, ventilated warehouse, away from sunlight, following first-in, first-out management.
• Transportation: Road, international express, air, and sea freight options. Protect against sharp objects and impacts. Packaging materials are recycled.
