PJ-063AH

Same Sky · DC Power Jack · Barrel Jack (2.0 mm, horizontal)

The PJ-063AH is a DC power barrel jack that accepts a 2.0 mm center-pin plug. It carries up to 8 A at 24 Vdc and includes a normally-closed switch terminal that opens when a plug is inserted, letting a design cut over from battery to external power automatically. It is a common DC input connector for adapters and wall supplies.

Pinout

Pin Name Type Function
1 TIP passive Center-pin contact (tip) of the barrel jack. Mates with the 2.0 mm center pin of the plug; typically carries the positive DC supply. Rated 24 Vdc / 8.0 A, contact resistance 30 mOhm max.
2 SLEEVE passive Outer sleeve / barrel contact. Mates with the outer conductor of the plug; typically the DC return (ground). Rated 24 Vdc / 8.0 A.
3 SW passive Switch / spring terminal. Normally shorted to the SLEEVE (pin 2) when no plug is inserted; the spring is deflected off the sleeve contact when a plug is mated, breaking the connection. Commonly used to detect plug insertion or route battery power when the jack is unplugged.
