ACF 04432 Product Diagram
Featuring a 5.08mm standard center space—compatible with most PCB layouts and commercial equipment—it operates across a temperature range of -40℃ to 105℃, making it suitable for indoor and semi-enclosed environments (e.g., office electronics or retail displays). Rated for 300V AC/DC and 10A, it handles moderate loads without sacrificing size, with a slim 11.2mm width that fits into dense control panels or slim device casings. Constructed with UL94 V-0 flame-retardant PA66 insulation and brass terminals, it meets global safety standards, while its 3500V surge voltage resistance protects connected components (e.g., IoT sensors, LED drivers) from transient electrical spikes. Whether used in smart home devices or light industrial tools, the MCF-04432 prioritizes space-saving design without compromising durability.
Slim PA66 Insulation: High-strength PA66 thermoplastic with UL94 V-0 flame retardancy reduces installation footprint (11.2mm width—20% slimmer than standard medium-power terminals). The material resists heat, mild chemicals, and mechanical wear, preventing short circuits in tight wiring clusters.
Brass Terminals: Corrosion-resistant brass ensures low electrical resistance (<0.002Ω per terminal), minimizing heat generation during current flow. Unlike aluminum alternatives, brass maintains conductivity and structural integrity over long-term use (up to 10 years in typical environments).
Zinc-Plated Steel Screws: Uses M2.5 zinc-plated steel screws for wire clamping. Zinc plating adds rust resistance, making the terminal suitable for humid spaces (e.g., retail refrigeration controls or bathroom smart mirrors).
Medium-Power Rating: 300V/10A capacity fits applications like LED lighting arrays (12V DC/5A), small water pumps (24V DC/8A), or IoT hub power lines (5V DC/2A)—avoiding overspecification and cost waste.
Surge Voltage Protection: Withstands 3500V transient spikes, shielding sensitive devices (e.g., programmable thermostats, POS system terminals) from power grid fluctuations or faulty electrical outlets.
Wire Compatibility: Accepts 30–16 AWG wires, covering thin signal wires (30 AWG for sensor data lines) and moderately thick power wires (16 AWG for LED drivers). This eliminates the need for multiple terminal sizes in compact systems.
Tool-Free Alignment: The 5.08mm center space aligns with pre-drilled PCB holes (common in commercial electronics), reducing assembly time. No specialized tools are required—mounts to standard 3.0mm holes with M2.5 screws (not included).
Supports 2P (2-pole) to 5P (5-pole) setups, with total length calculated as L = 5.08mm × Poles. For example, a 3P configuration has a total length of 15.24mm, fitting into 18mm-wide enclosures (e.g., smart thermostat casings).
Retail & Office Devices: Used in POS systems (cash registers, barcode scanners), office printers, and LED display controllers. Its slim width fits inside device casings, while surge protection safeguards against power spikes from shared electrical outlets.
Smart Home Hubs: Connects power and signal wires for smart lighting, doorbell cameras, and temperature sensors. The compact size fits into wall-mounted enclosures, and brass terminals ensure stable signal transmission for IoT data.
Small Manufacturing Auxiliaries: Suitable for sensor-based sorting machines (e.g., candy packaging lines) and portable power tools (e.g., battery-powered drills’ charging docks). The UL94 V-0 insulation meets workshop safety standards, while zinc-plated screws resist dust and mild oil exposure.
Food Service Equipment: Used in commercial coffee machines, small refrigerators, and countertop ovens. The -40℃ to 105℃ range handles temperature fluctuations, and PA66 insulation resists food-grade cleaners.
Home Theater Systems: Connects power wires for LED light strips, AV receivers, and streaming devices. The slim design fits behind entertainment centers, and surge protection prevents damage from power surges (e.g., during thunderstorms).
The "04432" is a model-specific identifier for manufacturing and inventory purposes, denoting key specifications: "04" = 4mm base height, "4" = 10A current class, "32" = 32mm maximum length (for 6P configuration). It does not affect installation or performance—focus on the terminal’s 300V/10A rating and 5.08mm center space for application matching.
Yes. Its 300V rating exceeds 240V AC requirements (common in European or commercial US households). For 240V applications (e.g., small space heaters), use 18 AWG wires (within 30–16 AWG range) and tighten screws to 3 lbf·in (max torque) to avoid insulation damage.
It fits standard 3.0mm (0.118-inch) mounting holes, common in PCBs and plastic enclosures. Use M2.5 mounting screws (length: 6–8mm) and avoid over-tightening—exceeding 3.5 lbf·in can crack the PA66 insulation.
Yes. The M2.5 zinc-plated screws and brass terminals work with both solid (e.g., 22 AWG solid for sensors) and stranded (e.g., 16 AWG stranded for LED drivers) wires. For stranded wires, twist the strands tightly before clamping to ensure full contact and prevent fraying.
Total length (L) = Center Space × Poles = 5.08mm × 4 = 20.32mm. Ensure your enclosure has at least 22mm of space (adding 1.68mm for wire clearance) to avoid wire crowding and potential short circuits.
