Eaton FER1B2821PN Receptacle - Fire & Smoke Certified
Part Number: FER1B2821PN
Quick Summary
FER1B2821PN receptacle is a fire- and smoke-certified bayonet connector used in rugged control panels. Engineers face misalignment, moisture ingress, and limited service access in tight installations. This solution offers IP67 sealing, UL94 V0 flammability, and RoHS compliance to meet harsh environment requirements. With 37 #16 contacts and crimped terminations, it reduces field maintenance time and replacement costs on critical automation lines. Designed for frequent mating cycles and vibration resistance, the square flange receptacle simplifies panel integration and improves overall reliability across industrial applications. Users benefit from standardized mating geometry and clearly documented tolerances that speed sourcing and spare-part planning.

FAQs
Begin by aligning the receptacle orientation to N, insert the square flange into the panel cutout, and secure with the appropriate mounting hardware. Use the threaded coupling to achieve a robust seal. Check that the mating connector is clean and the crimp contacts are properly seated. Note that connector accessories are not delivered by default and must be ordered separately to match your harness layout.
The aluminum shell is designed with a sealed interface and gaskets that prevent dust ingress and water ingress up to the IP67 standard. This makes the connector appropriate for outdoor, washdown, and rugged factory environments where exposure to moisture and particulates is common, reducing field failures and maintenance cycles.
Yes. The receptacle is configured for 37 cavities with #16 contact crimp terminals. When used with the correct crimp tooling and terminals, it provides reliable electrical performance and consistent mating integrity across thousands of cycles, supporting high-density interconnect needs in automation panels.
The FER1B2821PN operates from -40 °C to 100 °C and supports up to 500 mating cycles. This combination delivers resilience against thermal extremes and repeated connections in dynamic industrial settings, ensuring predictable performance in automation, rail, and process equipment.
Industries with stringent safety and environmental requirements—such as industrial automation, transportation (rail and aerospace), and power distribution—benefit most. The device’s fire and smoke certification, IP67 sealing, and RoHS compliance help meet regulatory standards while delivering reliable, long-life panel interconnects.
