Panasonic UK ACJ Series Automotive Relay 12V DC 20A
Panasonic UK ACJ Series automotive relay with 12V DC coil, SPDT contacts and 20A contact rating. Through-hole PC pin terminals for PCB mounting.
Panasonic UK ACJ Series Automotive Relay is a 12V DC SPDT relay rated at 20A for switching circuits in vehicle electrical systems.
The relay has a 12V DC coil and a Single Pole Double Throw (SPDT) contact configuration, allowing it to control two separate circuits or provide a changeover function. Its silver alloy contacts are designed to provide good conductivity and a long operational life by minimising electrical resistance and withstanding repeated switching cycles. With a 20A contact current rating, it can handle higher-power accessories such as headlights, cooling fans, winches, or aftermarket audio systems.
Overview
The relay is intended for standard automotive electrical systems. Its robust construction is described for stable performance under demanding conditions, including engine heat and vibration.
Mounting and Installation
The relay uses a through-hole mounting style with PC pin terminals for soldering onto printed circuit boards (PCBs). This arrangement supports a secure mechanical connection and suits applications where vibration resistance is important. Its compact dimensions of 43 mm x 33 mm x 15 mm make it suitable for densely packed electronic control units (ECUs) or custom fuse boxes within a vehicle.
