RH7024B-3.5-21/144473-5 24 V, 2 Position, Automotive Housing for Female Terminals

This document details a high-performance 24V automotive connector designed to meet the rigorous demands of modern vehicle electrical systems, ensuring reliable connectivity, exceptional durability, and broad compatibility in a wide range of automotive applications. Specifically, this product is a 2-position automotive housing for female terminals, part of the Junior Power Timer (JPT) series—a specialized line engineered to deliver consistent, high-quality performance in the harsh operating environments typical of automotive settings, with specific configurations tailored for seamless, secure wire-to-wire connections. As a critical component in vehicle power transmission systems, this connector is designed to uphold the strict standards of automotive manufacturing, providing long-term reliability even under extreme conditions.

The 24V Junior Power Timer connector, uniquely identified by TE Connectivity’s internal part number 144473-5 and internal product description CET 2 POS ASSY JPT, is a premium wire-to-wire connector specifically crafted for automotive applications that demand secure, efficient, and consistent power transmission. Manufactured under the AMP brand—a globally trusted name in automotive connectivity solutions with a legacy of engineering excellence—this connector features a precision-engineered 2-position housing tailored exclusively for female terminals. This design makes it ideal for mating with corresponding male terminals in vehicle wiring harnesses, ensuring a tight, stable connection that resists separation even under the constant vibration and mechanical stress experienced during vehicle operation. Its centerline spacing is precisely calibrated to 5 mm (0.197 inches), a critical specification that ensures accurate terminal alignment during installation, reduces assembly errors, and maintains stable electrical contact over the connector’s entire service life.

A key distinguishing feature of this Junior Power Timer connector is its sealable design, which provides robust protection against dust, moisture, and other environmental contaminants commonly encountered in automotive settings—such as under-hood, chassis, or exterior applications where exposure to the elements is inevitable. This advanced sealing capability is critical for maintaining reliable electrical performance, as it prevents the ingress of harmful substances that could cause signal loss, short circuits, or corrosion, all of which can compromise vehicle functionality and safety. Additionally, the connector is finished in a vibrant green color, a deliberate design choice that facilitates quick and easy identification in complex vehicle wiring systems, where dozens of connectors may be present. This visual distinction streamlines installation, inspection, and maintenance processes, reducing labor time and minimizing the risk of misconnection.

Electrically, the connector is rated for a nominal voltage architecture of 24V, making it perfectly suited for heavy-duty automotive systems, commercial vehicles (such as trucks, buses, and construction equipment), and other industrial automotive applications that require higher voltage power transmission. Its female terminal housing design incorporates a secure retention mechanism that firmly holds terminals in place, ensuring consistent electrical contact and preventing terminal backout—a common cause of connection failure in automotive systems. Furthermore, the connector boasts an impressive operating temperature range of -40 °C to 100 °C (-40 °F to 212 °F), allowing it to perform reliably in extreme weather conditions, from frigid winter temperatures in cold climates to the high heat of under-hood environments during summer operation, without any degradation in performance or structural integrity.

Constructed with high-quality materials that fully comply with strict automotive industry standards (including ISO and SAE specifications), the 24V Junior Power Timer connector boasts exceptional mechanical strength and long-term durability. The housing is manufactured from PA 66, a rugged, high-performance thermoplastic renowned for its outstanding resistance to impact, heat, chemicals, and UV radiation—all of which are common stressors in automotive environments. This material choice ensures the connector can withstand the rigors of daily use, including exposure to engine oils, coolants, and other automotive fluids, while maintaining its structural integrity for years. Additionally, the connector is part of TE Connectivity’s platform-based wire-to-wire connection system, which emphasizes compatibility across different vehicle models, efficient production processes, and consistent, reliable performance—making it a preferred choice for both original equipment manufacturers (OEMs) and aftermarket professionals.

In addition to its core electrical and mechanical features, this 24V Junior Power Timer connector is designed with practicality and user-friendliness in mind for automotive assembly and maintenance technicians. Its green housing serves as a clear visual identifier, allowing technicians to quickly locate and distinguish it from other connectors in complex vehicle wiring harnesses—even in low-light conditions—thereby streamlining installation, inspection, and replacement processes. The precise 5 mm (0.197 inches) centerline spacing not only ensures accurate terminal alignment but also optimizes the use of space in tight under-hood or chassis locations, where packaging efficiency is critical for accommodating other vehicle components. The connector’s ergonomic design also simplifies mating and unmating, reducing the force required during assembly while maintaining a secure connection.
