Potter-Brumfield R50-E2-Y1-12VDC PC Board Relay

Potter & Brumfield R50-E2-Y1-12VDC PC Board Relay is a compact Form C (SPDT) switch designed for PCB mounting. With a 12 V DC coil, it can switch up to 2 A at 28 V DC on its common-to-NO and common-to-NC contacts, making it well suited for control and signal tasks on embedded boards and automation modules. This unsealed PC-board relay belongs to the 18 mm R50 family, offering a small footprint around 0.7 in (18 mm) wide that fits densely populated PCBs. It features PC terminals for straightforward through-hole mounting or socket compatibility, enabling easy replacement in existing equipment. Typical applications include instrumentation panels, relay boards, and small automation controllers where a compact, reliable switch is needed to isolate control circuitry from the load while handling moderate DC loads. As part of the Potter & Brumfield line (now TE Connectivity), the R50 series provides a 2 A load rating in a compact 18 mm footprint, aligning with legacy designs that require a 12 VDC coil and SPDT configuration.
