The Pearl PWN790 is a premium line of fully insulated slide‑on female terminals designed for automotive and industrial wiring applications. Each pack contains 25 units, making it an ideal choice for both large-scale installations and small repair jobs.

Key Features

• Color Code: Vibrant blue, providing instant visual identification of the connector type within a wiring harness.
• Current Rating: Rated for up to 15 A, ensuring reliable performance in moderate power circuits.
• Thread Size: Standard 6.3 mm (1/4‑inch) thread, compatible with a wide range of automotive terminals and connectors.
• Fully Insulated: Each terminal is completely covered by high‑quality insulation, preventing accidental shorts and enhancing safety.
• Slide‑On Design: The slide‑on mechanism allows for quick and secure attachment to the corresponding male connector without the need for additional tools.
• Durable Construction: Made from high‑strength plastic that resists abrasion, vibration, and temperature extremes typical in automotive environments.

Applications

The PWN790 connectors are engineered to meet the demands of a variety of electrical systems. Common uses include:

• Vehicle Wiring Harnesses: Ideal for connecting sensors, switches, and control modules.
• Lighting Systems: Suitable for interior and exterior lighting circuits where reliable connections are essential.
• Power Distribution: Effective in distributing power to accessories such as audio systems, auxiliary batteries, or aftermarket devices.
• Industrial Automation: Can be employed in control panels and machinery that require robust, insulated terminals.

Installation Guide

1. Prepare the Wire: Strip the insulation to expose approximately 6 mm of conductor. Ensure the wire is clean and free from burrs.
2. Insert the Wire: Slide the stripped end into the terminal’s opening until it reaches the bottom of the cavity.
3. Secure with the Slide‑On Mechanism: Gently slide the connector onto the male counterpart. The internal spring mechanism will lock the connection in place, providing a firm and stable bond.
4. Check for Continuity: Verify that the connection is secure by testing continuity or inspecting visually for any gaps.

Technical Specifications

Quality Assurance

The PWN790 series undergoes rigorous testing to ensure each terminal meets stringent performance standards. Quality checks include:

• Electrical continuity and resistance measurements.
• Mechanical pull tests to confirm secure attachment.
• Environmental stress testing for temperature, humidity, and vibration resilience.

Compatibility

These connectors are designed to be fully compatible with:

• Standard automotive terminal blocks.
• Other 6.3 mm slide‑on female terminals from leading manufacturers.
• Various wire gauges typically used in vehicle electrical systems (commonly 18–22 AWG).

Maintenance Tips

• Inspect connections periodically for signs of wear or corrosion, especially in harsh environments.
• Avoid over‑tightening the slide mechanism to prevent damage to the internal spring.
• Store unused connectors in a dry, temperature-controlled environment to preserve insulation integrity.
