FR 6N Product Diagram
Featuring a 5.08mm standard center space—compatible with most PCB layouts and industrial equipment—it delivers consistent performance across a temperature range of -40℃ to 105℃, making it suitable for both indoor and semi-enclosed environments. Rated for 300V AC/DC and 6A, it balances moderate current handling with a slim profile (12.7mm width), ideal for dense control panels or devices with limited wiring space. Constructed with UL94 V-0 flame-retardant PA66 insulation and brass terminals, it meets global safety standards, while its 4000V surge voltage resistance protects connected components from transient electrical spikes. Whether used in commercial electronics or light industrial systems, the RKM-6N prioritizes space-saving design without compromising durability.
Narrow-Body PA66 Insulation: Made of high-strength PA66 thermoplastic with UL94 V-0 flame retardancy. Its slim 12.7mm width reduces installation footprint, while the material resists heat, chemicals, and mechanical wear—preventing short circuits in tight wiring clusters.
Brass Terminals: Corrosion-resistant brass ensures low electrical resistance, minimizing heat generation during current flow. Unlike aluminum alternatives, brass maintains conductivity and structural integrity over long-term use.
Stainless Steel Screws: Uses M2.5 stainless steel screws for wire clamping. Stainless steel offers superior rust resistance compared to standard steel, making the RKM-6N suitable for humid environments (e.g., commercial kitchens or HVAC closets).
Medium-Power Rating: 300V/6A capacity fits medium-load applications (e.g., LED lighting arrays, small pumps, or sensor power lines) without overspecifying.
Surge Voltage Protection: Withstands 4000V transient spikes, shielding sensitive devices like IoT sensors or programmable thermostats from power grid fluctuations.
Wire Compatibility: Accepts 32–16 AWG wires, covering thin signal wires (32 AWG for IoT modules) and moderately thick power wires (16 AWG for LED drivers). This eliminates the need for multiple terminal sizes in compact systems.
Tool-Less Alignment: The 5.08mm center space aligns with pre-drilled PCB holes, reducing assembly time. No specialized tools are required for mounting, as the terminal fits standard 3.2mm mounting holes.
Supports 2P (2-pole) to 6P (6-pole) setups, with total length calculated as L = 5.08mm × Poles. For example, a 4P configuration has a total length of 20.32mm, fitting into 25mm-wide enclosures common in commercial electronics.
Retail & Office Equipment: Used in POS (Point of Sale) systems, office printers, and LED display controllers. Its narrow width fits inside slim device casings, while surge protection safeguards against power spikes from shared electrical outlets.
HVAC Controls: Integrates into thermostat modules, duct sensors, and small fan drives. The stainless steel screws resist humidity in HVAC closets, preventing rust-related loose connections.
Food Processing Auxiliary Equipment: Suitable for small conveyors, sensor-based sorting machines, and packaging tools. The UL94 V-0 insulation meets food industry safety standards, while the narrow body fits into sanitized equipment enclosures.
Automotive Aftermarket Devices: Used in car audio systems, GPS trackers, and backup camera power lines. The -40℃ to 105℃ temperature range withstands extreme cabin temperatures (from cold winters to hot summers).
Smart Home Hubs: Connects power and signal wires for smart lighting, doorbell cameras, and temperature sensors. Its compact size fits inside wall-mounted smart home enclosures, while brass terminals ensure stable signal transmission.
The "N" denotes "narrow-body," referring to the terminal’s 12.7mm width—30% slimmer than standard RKM-series terminal blocks (e.g., FR-35). This design is optimized for space-constrained applications like compact IoT devices or slim HVAC controllers.
Yes. Its 300V rating exceeds 12V DC requirements, and the -40℃ to 105℃ temperature range withstands automotive cabin conditions. Ensure wires are 32–16 AWG (e.g., 18 AWG for GPS tracker power lines) for secure clamping.
It fits standard 3.2mm (0.125-inch) mounting holes, common in PCBs and aluminum control panels. Use M3 mounting screws (not included) to secure the terminal—avoid over-tightening (max 3 lbf·in) to prevent cracking the PA66 insulation.
Yes. The brass terminals and M2.5 stainless steel screws work with both solid (e.g., 22 AWG solid wire for sensors) and stranded (e.g., 16 AWG stranded wire for LED drivers) wires. For stranded wires, twist the strands tightly before clamping to ensure full contact.
Total length (L) = Center Space × Poles = 5.08mm × 5 = 25.4mm. Ensure your enclosure has at least 27mm of space (adding 1.6mm for wire clearance) to avoid wire crowding and potential short circuits.
