NR-SD-6V Mini Telecom Relay Form 1C 6VDC Coil 1A PCB Relay

The NR-SD-6V Mini Telecom Relay is a compact, high-reliability PCB-mounted electromechanical relay designed for telecommunications equipment, signal switching systems, instrumentation, security devices, and low-power electronic control applications. Featuring a 6V DC coil and a Form 1C (SPDT) contact configuration, this relay delivers precise and dependable switching performance in a miniature footprint.

With its ultra-compact dimensions of 20 × 10 × 10 mm, the NR-SD-6V is optimized for high-density PCB layouts where space is limited but reliable signal switching is essential. Its small form factor makes it well suited for modern electronic designs that require efficient integration without sacrificing performance or durability.

The Form 1C contact arrangement provides a single changeover pole, allowing flexible switching between two circuit paths. With a maximum switching current of 1A and an electrical rating of 1A at 20VDC, the relay is ideal for signal-level switching, communication lines, monitoring systems, and low-power control applications requiring accuracy and stability.

Operating from a 6V DC coil supply, the NR-SD-6V features a coil resistance of 220 and a coil power consumption of approximately 200mW. This efficient coil design ensures reliable actuation while minimizing energy usage, making it suitable for both continuous and intermittent duty operation in electronic systems.

The relay utilizes gold alloy (AuCo) contacts, which provide excellent conductivity, low contact resistance, and strong resistance to oxidation. This ensures stable signal integrity and long operational life, particularly in sensitive telecommunications and data applications.

For enhanced safety and electrical protection, the NR-SD-6V provides 1kV isolation voltage between the coil and contact circuits. UL and CSA approvals confirm compliance with internationally recognized safety and quality standards, ensuring dependable performance in professional environments.

The polarized design ensures correct installation orientation, reducing assembly errors and improving reliability in automated PCB manufacturing processes.
