NR-SLD-24V Mini Telecom Relay Form 1C 24VDC Coil 1A PCB Relay

The NR-SLD-24V 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 24V DC coil and a Form 1C (SPDT) contact configuration, this relay provides precise and stable switching performance in a miniature package optimized for space-constrained PCB designs.

With its ultra-compact dimensions of 20 × 10 × 10 mm, the NR-SLD-24V is ideal for high-density electronic assemblies where board space is limited but reliable switching is essential. Its small footprint allows seamless integration into modern telecom and control systems without compromising electrical performance or durability.

The Form 1C contact configuration provides a single changeover pole, enabling flexible switching between two circuits. With a maximum switching current of 1A and an electrical rating of 1A at 20VDC, the relay is well suited for signal-level switching, communication lines, monitoring circuits, and low-power control applications requiring precision and long-term stability.

Operating from a 24V DC coil supply, the NR-SLD-24V features a coil resistance of 6k and a very low coil power consumption of only 120mW. This ultra-efficient coil design reduces energy usage significantly, making it ideal for systems where power efficiency is critical or where multiple relays are used in parallel.

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

For enhanced electrical safety and system protection, the NR-SLD-24V provides 1kV isolation voltage between the coil and contact circuits. UL and CSA approvals confirm compliance with internationally recognized safety and quality standards, making it suitable for professional and industrial-grade applications.

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