Overview
The PJ-002AH is a right-angle, through-hole DC power jack designed for reliable power delivery in compact electronic assemblies. It features a standard 2.1mm center pin diameter and is rated for up to 5A at 24VDC, making it suitable for high-current applications. The inclusion of a normally closed internal switch allows for automatic power source switching, such as disconnecting a battery when an external adapter is plugged in.
Why Choose This Part
This jack offers a high 5A current rating, which is significantly higher than standard 2.5A barrels. Its PBT housing is UL94V-0 flammability rated and it features a durable design capable of 5000 mating cycles.
Applications
High-Current DC Power Supply
Ideal for 12V or 24V power input stages requiring up to 5A of continuous current.
Battery Charging Circuits
Utilizes the internal NC switch to toggle between internal battery power and external DC wall adapter power.
Industrial Control Modules
Provides a robust mechanical connection for DIN-rail or panel-mounted electronics requiring a common 2.1mm barrel interface.
Consumer Electronics
Commonly used in networking equipment, audio devices, and portable electronics that utilize standard barrel connectors.
