Eaton FER1D2821SX Bayonet Connector - Fire & Smoke
Part Number: FER1D2821SX
Quick Summary
Eaton FER1D2821SX bayonet connector is a fire and smoke certified, high‑reliability wiring solution for harsh industrial enclosures. Engineers often struggle with maintaining seal integrity and quick field replacements when penetrations are exposed to dust, moisture, or temperature swings. The FER1D2821SX family delivers IP67 protection, UL94 V0 flammability, and RoHS/REACH compliance to support safety and regulatory requirements across automation, transportation, and energy sectors. Its compact 55.3 mm by 48.1 mm shell and 37 cavity layout enable dense panel wiring while preserving serviceability and future expansion. Designed for compatibility with standard crimp terminals and a threaded coupling, it helps reduce downtime and total cost of ownership in automation panels.

Fire and smoke certification with UL94 V0 flammability ensures enclosure penetrations meet strict safety standards, reducing the risk of flame propagation in critical systems. The aluminum shell and long service life support demanding industrial use, while RoHS and REACH compliance simplify sustainability goals and regulatory reporting. IP67 ingress protection keeps internal electronics safe from dust and water ingress in rugged environments, minimizing unplanned downtime and warranty claims. A high-density 37 cavity layout on a compact shell enables efficient harness design, reducing panel footprint and installation time. The 21 layout and crimp contact design support reliable, high‑integrity signal and power distribution for automation controllers. Thread coupling and the option where the insulator is not mounted provide flexible installation paths, speeding assembly in tight panels. With a broad operating temperature range of -40 °C to 100 °C, this connector maintains performance in extreme environments and reduces the need for multiple part variants. The 500 mating cycles specification aligns with routine maintenance schedules, delivering predictable lifecycle cost and return on investment for industrial installations. Salt spray endurance of 500 hours further confirms corrosion resistance in coastal or humid environments, contributing to lower replacement frequency and total cost of ownership.

FAQs
Begin by selecting the mating plug and socket from the FER1 family and verify the insulator orientation is as required (insulator not mounted for this variant). Fit 37 #16 crimp contacts, then thread the coupling until fully seated to achieve IP67 sealing. Note that connector accessories are not included and must be ordered separately; ensure mating cycles of 500 are considered for field life.
The FER1D2821SX family carries UL94 V0 flammability certification, along with RoHS and REACH compliance, and IP67 protection. These certifications support safety, regulatory alignment, and environmental responsibility for penetrations in control panels and hazardous environments. When specifying in a bill of materials, reference these standards to ensure regulatory continuity across facilities.
Yes. The FER1D2821SX features 37 cavities designed for #16 crimp contacts within a 21‑position layout, delivering high contact density in a compact aluminum shell. The contact type is crimp, and the design supports up to 500 mating cycles, which aligns with typical maintenance plans for automation equipment and reduces replacement frequency.
This connector operates from -40 °C to 100 °C and carries IP67 ingress protection, making it suitable for harsh environments. The aluminum shell (size 28) is robust yet lightweight, and it supports up to 500 mating cycles. It is designed for demanding automation panels, outdoor installations, and machinery enclosures where temperature and moisture fluctuations are expected.
The FER1D2821SX supports 500 mating cycles, aiding predictable maintenance planning and reducing downtime. Its IP67 rating, UL94 V0 safety certification, and RoHS/REACH compliance mitigate regulatory risk and material substitution costs. While the 37‑contact density improves wiring efficiency, the insulated, threaded coupling minimizes leak paths, enabling longer service intervals and a lower total cost of ownership for industrial panels.
