Electromagnetic Relay Panasonic JJM2W12 12V DC 12A 2 contacts

Panasonic JJM2W12 is an electromagnetic relay with a 12 V DC coil and two changeover contacts rated for 12 A switching current. It is intended for general-purpose low-voltage switching in control panels, automation systems and electronic equipment. The relay's compact size and standard PCB pinout simplify replacement and integration while providing reliable switching for circuits and loads up to the specified rating.

Advantages

The Panasonic JJM2W12 offers a 12 V DC coil voltage and two robust contacts capable of switching up to 12 A, ensuring compatibility with a wide range of low-voltage applications. Its compact construction and standard print/PCB footprint make it easy to mount or replace in control panels and electronic assemblies. The relay is built to provide stable electrical performance and repeatable contact action under normal operating conditions.

Suitable for

• Control panels and switchboards
• Industrial and building automation
• Electronic equipment and PCB-based assemblies
• General-purpose low-voltage switching tasks

How to use

Mount the relay on the PCB according to the standard pinout and solder all pins securely. Apply the specified 12 V DC to the coil terminals to operate the contacts; observe correct polarity if specified by the circuit. Connect load and supply circuits to the appropriate common and normally open/normally closed contacts, ensuring the switched current does not exceed 12 A and that voltage ratings for the load are respected.

Recommendations

Use the relay within its rated coil voltage and switching current limits. Provide appropriate protection such as fuses or circuit breakers for loads near the 12 A limit, and follow standard PCB layout and thermal management practices to ensure reliable operation and longevity.
