TE Connectivity (AMP) 2322347-3 is a high-performance 12-pin hybrid female connector housing engineered specifically for demanding automotive and industrial electrical systems. This innovative connector integrates two contact systems in a single compact shell—8 Micro Quadlok (MQS) 0.64mm signal contacts and 4 MCP 2.8mm power contacts—enabling simultaneous transmission of low-current signals and high-current power, eliminating the need for multiple separate connectors and simplifying wiring harness design.
Core Design & Material Advantages
Hybrid Contact Configuration: The 8 Micro Quadlok (MQS) signal contacts (0.64mm terminal size) support precise low-voltage signal transmission (ideal for sensors, switches, and control modules), while the 4 MCP 2.8mm power contacts handle higher current loads (suitable for lighting, small motors, and power supply circuits). This 2-in-1 design reduces installation space and wiring complexity in tight automotive environments.
Durable Green PBT Housing: Constructed with glass-fiber reinforced polybutylene terephthalate (PBT) material, the connector housing offers exceptional mechanical strength, impact resistance, and flame retardancy (compliant with UL94 V-0). The green color coding allows for quick identification during assembly and maintenance, reducing wiring errors.
Secure Latch Lock Mechanism: Equipped with an integrated positive-locking latch that creates an audible "click" when fully mated, ensuring a vibration-resistant connection even in high-shock environments (e.g., engine bays, chassis wiring). The latch prevents accidental disconnection caused by vehicle movement, temperature fluctuations, or external forces.
Wide Operating Temperature Range: Rated for -40°C to +105°C, this connector withstands extreme temperature variations—from freezing winter conditions to the heat of engine compartments—without compromising performance. It also resists exposure to automotive fluids (oil, coolant, fuel) and humidity, ensuring long-term reliability.
Technical Specifications & Compliance
Pitch & Dimensions: 2.5mm pin pitch (0.098in) with 3.9mm row spacing, double-row layout for high-density connections; compact overall size (length x width x height: tailored to TE’s standard Micro Quadlok footprint) for space-constrained applications.
Termination Method: Crimp-style connection compatible with TE’s corresponding male terminals (e.g., MQS 0.64mm crimp terminals for signal, MCP 2.8mm crimp terminals for power), ensuring fast, tool-free assembly and excellent electrical conductivity.
Compliance & Certifications: RoHS compliant (free of lead, cadmium, and other restricted substances), meets automotive industry standards (ISO, SAE) for electrical performance and environmental durability.
Wide Application Scenarios
This versatile connector is a staple in automotive electronics and industrial control systems, including:
Automotive engine control units (ECUs), transmission control modules (TCMs), and body control modules (BCMs)
Car sensors (temperature, pressure, position sensors), lighting systems (LED headlights, interior lighting), and small motors (window regulators, door locks)
Industrial automation equipment, agricultural machinery, and heavy-duty vehicles (trucks, construction equipment)
Marine and off-road vehicle electrical systems (resistant to moisture, dust, and vibration)
Reliability & Compatibility
Designed for long service life (≥10,000 mating cycles), the TE 2322347-3 ensures consistent electrical performance with low contact resistance (≤20mΩ). It is fully compatible with TE’s matching male headers and crimp tools, enabling seamless integration into existing wiring harnesses. Whether for OEM production or aftermarket replacement, this connector delivers the durability, versatility, and performance required for critical electrical connections in harsh environments.
