Frequently Asked Questions
What type of relay contact does the R50-E2Y1-6 have?
It uses a single-pole double-throw (SPDT) configuration, also called 1 Form C, suitable for switching one circuit between two outputs.
What does the “6” suffix mean in the part number?
The suffix indicates a 6VDC coil voltage rating.
Is this relay sealed?
Yes. It features a sealed, tape-covered polyester case that allows immersion cleaning during manufacturing.
Can this relay handle AC and DC loads?
Yes. It’s rated for 2A at 28VDC and 1A at 120VAC (resistive loads).
Is it suitable for modern PCB replacement?
Yes. The R50-E2Y1-6 follows standard 0.1-inch grid pin spacing, making it compatible with many PCB footprints used in control and telecom equipment.
Built with the precision of mid-century American relay design, the R50-E2Y1-6 carries the Potter & Brumfield legacy into the next generation of restoration and repair work.
