Key Considerations

Temperature Rating: Choose terminals rated above the maximum operating temperature of your application (up to 1,200°F for ceramic blocks). Wire Gauge Compatibility: Ensure the terminal supports your wire size (commonly 24–10 AWG). Insulation Type: PVDF or ceramic insulation is preferred for extreme heat; noninsulated terminals allow easier inspection.

Mounting Style: Options include screwless, pluggable, through-hole, or clamp-style terminals depending on your circuit design. Supplier Location: All listed suppliers are US-based or provide US shipping, ensuring compliance with domestic sourcing requirements. These suppliers provide a range of high-temperature resistant terminals suitable for optical circuits, offering both durability and electrical reliability in extreme thermal conditions.
