About Power Relays

Power relays are electromagnetic switches designed to control higher current loads than signal relays, typically above 2 amps. They isolate control circuits from power circuits, protecting sensitive electronics while enabling management of motors, heaters, and lighting systems. Their robust construction handles inrush currents and arcing that would damage smaller switching components.

Industrial-grade power relays feature enhanced safety certifications, wider temperature tolerances, and specialized contact materials. These characteristics make them essential for industrial automation, energy management systems, and equipment requiring fail-safe operation under electrical stress or environmental extremes.

Packaging

Available in Bulk packaging for prototype development or low-volume production needs. PCX provides anti-static handling for all relay shipments.

Frequently Asked Questions

Question: Is this relay suitable for switching AC motor loads?
Answer: Yes, its 2500VA rating and AgSnO contacts handle inductive loads like small motors, but always derate for inrush currents.

Question: What does “fully sealed” mean for this component?
Answer: The relay is hermetically sealed to IP67-equivalent standards, preventing contamination from dust, humidity, and chemical vapors.

Question: Can I use this with 24VDC systems?
Answer: No – the 12VDC coil requires 8.4-12VDC. For 24V operation, select a relay with matching coil voltage.

Question: Why is this part marked obsolete?
Answer: Panasonic discontinued production, but PCX maintains stock for maintenance and legacy system repairs.

Question: Do you provide the datasheet?
Answer: Yes: Download JS1-12V-F Datasheet (PDF)

Question: What are alternatives if stock depletes?
Answer: PCX engineers can recommend functional equivalents from Panasonic’s current portfolio based on your requirements.
