14Pin Black TE AMPSEAL Connector Wire-to-board Connector 776273-1 – TS30256-14P-21 High-Density Female Housing for Automotive and Industrial Control Systems

When precision, durability, and environmental protection are non-negotiable, the TS30256-14P-21 stands out as a top-tier solution in the AMPSEAL series of sealed connectors. Designed as the female counterpart to the TS30256-14P-11 male plug, this 14-pin black housing delivers robust, vibration-resistant connections ideal for wire-to-board applications in cars, yachts, UTVs, and industrial equipment. Engineered to meet or exceed the performance of the 776273-1 specification, it integrates seamlessly into modern electronic systems where reliability under stress is critical. Whether used in factory replacements, custom audio harnesses, or control modules, this connector ensures stable signal transmission and long-term integrity in demanding environments.

Engineered for Secure, Long-Term Wire-to-Board Integration

The TS30256-14P-21 is purpose-built for wire-to-board applications where a stable, sealed connection between a cable harness and a printed circuit board is essential. As a female housing in the AMPSEAL series, it mates securely with the TS30256-14P-11 male plug, forming a robust interface that resists vibration, shock, and environmental exposure. Its design supports direct PCB mounting or inline installation, making it ideal for use in audio control units, engine management systems, marine electronics, and industrial control panels where consistent electrical performance is paramount.

Two-Stage Locking System Prevents Terminal Backout

Unlike basic connectors, the TS30256-14P-21 features a two-piece contact retention system. After terminals are inserted into the housing, a secondary locking wedge is slid into place, applying uniform pressure across all 14 contacts. This dual retention—primary terminal latch plus mechanical wedge lock—ensures that wires remain firmly seated even under continuous vibration or thermal expansion. The result is a connection that maintains integrity over time, reducing the risk of intermittent faults and system failures in critical applications.

Advanced Mat Seal Technology for Superior Environmental Protection

Each terminal cavity is equipped with a built-in mat seal containing a sealing diaphragm. When a terminal is inserted, the diaphragm is pierced, creating a watertight seal around the wire insulation. This prevents moisture, dust, and chemical ingress, making the connector suitable for use in high-humidity or wash-down environments. If a terminal is removed during servicing, a sealing plug must be installed to restore the cavity’s protection—ensuring that the housing remains sealed and functional throughout its lifecycle.

High-Density Three-Row Layout for Efficient Space Utilization

With a 4.0mm centerline pitch and a three-row contact grid, the TS30256-14P-21 maximizes pin density while maintaining excellent wire management. This compact yet organized layout is ideal for applications where space is limited but multiple signals or power lines must be routed reliably. The structured design simplifies assembly, reduces wiring errors, and supports clean, professional harness builds in both OEM and aftermarket settings.

Robust Construction from Industrial-Grade Materials

Manufactured from either PBT+GF15% or PA66+GF30%, the black housing delivers exceptional resistance to heat, impact, and chemical exposure. These glass-reinforced thermoplastics maintain their mechanical properties across a wide temperature range, preventing warping, cracking, or degradation in harsh environments. The durable construction ensures long service life in under-hood installations, marine electronics, and off-road vehicle systems.

Compatible with a Range of High-Performance Terminals and Headers

The TS30256-14P-21 accepts copper alloy, brass, and phosphor bronze terminals—offering flexibility in conductivity, cost, and spring force. It also integrates seamlessly with standard PCB mount headers, enabling direct board attachment for compact control modules. Whether replacing a factory connector or building a custom interface, this housing supports reliable, serviceable connections that meet automotive and industrial standards.

Ideal for Automotive, Marine, and Off-Road Applications

Common uses include:

• Replacement connectors for car stereo and infotainment systems

• Marine electronics integration in yachts and boats

• Control wiring in UTVs, ATVs, and agricultural machinery

• Industrial automation and sensor networks

• Custom wire harnesses for OEM and aftermarket upgrades

Its modular design supports both prototyping and mass production with ease.
