FE 1.5-5.08-04-T1-XX Product Diagram
Featuring a 5.08mm center space and 300V/15A rating, it integrates a "T1" thermal-enhanced design—including heat-resistant PA66 insulation and nickel-plated brass terminals—to maintain performance in extreme heat. With a 4000V surge voltage resistance and UL94 V-0 flame retardancy, it meets industrial safety standards for high-heat applications like automotive under-hood systems or industrial ovens. The "04" in its model indicates a 4-pole base configuration, offering plug-and-play compatibility with multi-circuit systems. Whether used in high-temperature factories or outdoor power modules, the FE 1.5-5.08-04-T1-XX delivers consistent connectivity in harsh thermal conditions.
Thermal-Enhanced PA66 Insulation: Modified PA66 material with glass fiber reinforcement retains structural integrity at 125℃ (257℉)—preventing melting or warping in industrial ovens or automotive engine bays. It still meets UL94 V-0 flame retardancy, self-extinguishing within 10 seconds of flame exposure.
Nickel-Plated Brass Terminals: Nickel plating adds heat resistance (up to 150℃) and corrosion protection, unlike standard brass terminals. This ensures low resistance and minimal heat generation even at maximum 15A current.
Heat-Resistant Screw Coating: M3 steel screws feature a ceramic coating that resists thermal expansion, maintaining tight connections as temperatures fluctuate (e.g., from -40℃ to 125℃ in automotive applications).
Consistent Power Handling: 300V/15A rating supports low-to-medium power circuits, including industrial fan drives (24V DC/10A) and high-temp sensor power lines (12V DC/5A).
Surge Voltage Protection: 4000V transient resistance shields connected devices (e.g., temperature sensors, motor controllers) from electrical spikes caused by heat-induced power fluctuations.
Wire Compatibility: Accepts 30–14 AWG wires, covering thin signal wires (30 AWG for thermocouples) and thicker power wires (14 AWG for small motors). The terminal’s clamping mechanism accommodates both solid and stranded wires.
4-Pole Base Configuration: The "04" denotes a 4-pole default setup (total length: 5.08mm × 4 = 20.32mm), eliminating the need for custom pole assembly. Additional poles can be added (up to 8P) for larger systems.
Torque Guidance: Requires 5 lbf·in of torque for M3 screws—use a torque wrench to ensure proper clamping without damaging the thermal-enhanced insulation.
Stackable Design: Supports vertical stacking with compatible EMD-series terminals, ideal for dense control panels in high-heat environments (e.g., industrial oven control units).
PCB Compatibility: The 5.08mm center space aligns with standard PCB hole patterns, simplifying soldering and assembly in mass-produced high-temp devices (e.g., automotive ECU sensors).
Engine Sensors & Actuators: Connects power and signal wires for temperature sensors, fuel injectors, and ignition coils. The -40℃ to 125℃ range withstands engine bay heat (up to 120℃), while nickel-plated terminals resist oil and coolant corrosion.
EV Charging Auxiliaries: Used in EV on-board charger (OBC) wiring for temperature monitoring modules. The thermal-enhanced insulation handles heat generated during fast charging, preventing insulation degradation.
Industrial Ovens & Furnaces: Integrates into temperature control panels, heating element power lines, and door switch circuits. The 125℃ tolerance matches oven ambient temperatures, while UL94 V-0 flame retardancy reduces fire risk.
Plastic Molding Machines: Connects sensors and small motors in heated barrel zones. The surge protection safeguards against power spikes from heating element cycling, ensuring consistent machine operation.
Solar Panel Junction Boxes: Used in solar array wiring for bypass diodes and temperature sensors. The -40℃ (cold winters) to 125℃ (hot summers) range handles outdoor temperature extremes, while nickel-plated terminals resist UV-induced corrosion.
Aviation Ground Equipment: Suitable for aircraft maintenance tools (e.g., engine heaters) that operate in extreme cold (-40℃) or hot (100℃) tarmack conditions.
The "T1" refers to the terminal’s thermal-enhanced design, including modified PA66 insulation (125℃ max temp) and nickel-plated brass terminals. This distinguishes it from standard EMD models (max 105℃) and makes it suitable for high-heat applications like engine bays.
Yes. Its 300V rating exceeds 240V AC requirements, and the 15A capacity fits medium-load circuits (e.g., 240V AC/5A industrial fans). Ensure wires are 30–14 AWG (e.g., 16 AWG for 240V lines) and use a torque wrench to meet the 5 lbf·in screw specification.
The 4-pole setup (20.32mm total length) is a base module—you can add 1-pole extensions (5.08mm each) to create 5P, 6P, or up to 8P configurations. For example, a 6P system has a total length of 5.08mm × 6 = 30.48mm. Ensure the enclosure has enough space for extensions and wire clearance.
Yes. It accepts 30 AWG thermocouple wires (common in high-temp sensors), and the nickel-plated terminals minimize signal interference. For best results, use stranded thermocouple wires (twisted tightly) to ensure secure clamping and accurate temperature readings.
No—installation steps are identical to standard EMD terminals. Use M3 steel screws (included for wire clamping) and 3.2mm mounting holes. The only difference is temperature limits: avoid exceeding 125℃ to preserve the insulation’s thermal properties.
