Eaton FER1D2821SY Bayonet Connector - Fire/Smoke Certified
Part Number: FER1D2821SY
Quick Summary
Eaton FER1D2821SY bayonet connector is a 37‑way female plug designed for harsh industrial enclosures and high-density wiring. Designers often struggle to meet fire and smoke certifications while maintaining compact, vibration‑resistant connections in tight panel layouts. With IP67 ingress protection, UL94 V0 flammability, and RoHS/REACH compliance, this connector supports safe, standards‑driven installations. Its aluminium shell and Souriau VGE1 family design reduce installation time and lifecycle costs, aligning with high‑reliability automation projects and minimizing downtime in critical systems.

FAQs
FER1D2821SY uses crimp contact technology for 37 #16 wires and features a thread coupling design for secure mating. Installation requires matching crimp terminals, proper torque on the coupling thread, and alignment of the X orientation. Ensure mating with compatible housing and accessory parts ordered separately. The mating cycles (up to 500) indicate long‑term reliability in repeated connect/disconnect scenarios.
The connector is fire and smoke certified and offers IP67 ingress protection. It also meets UL94 V0 flammability, RoHS, and REACH compliance. With these certifications, it is suitable for safety‑critical installations in industrial, rail, and aerospace environments, ensuring regulatory alignment and material sustainability.
Yes. The IP67 rating, fire/smoke certification, aluminium shell, and 37‑cavity configuration make it well suited for rail and aerospace panel assemblies that demand rugged sealing, electrical integrity in harsh climates, and compliance with strict safety standards, while preserving compact form factors.
This is a straight plug with thread coupling and crimp contacts. Use compatible crimp terminals for 37 #16 contacts and verify proper thread engagement to maintain IP67 sealing. The aluminium shell size 28 offers a balance of light weight and mechanical strength, supporting straightforward field assembly and serviceability.
Choosing FER1D2821SY delivers durable sealing (IP67), fire/smoke safety compliance, and a long service life with up to 500 mating cycles, which reduces maintenance interventions and downtime. Its rugged construction and standardization with Souriau VGE1 families also lower lifecycle costs through better spare‑part availability and easier system integration.
