Eaton FER1B2821PX Fire & Smoke Bayonet Connector - IP67
Part Number: FER1B2821PX
Quick Summary
Eaton FER1B2821PX is a fire and smoke certified bayonet connector for demanding industrial wiring enclosures. Across plants and panel-builders, securing reliable mating under harsh conditions is a frequent challenge. This connector meets UL94 V0, IP67, and fire & smoke certifications, boosting safety and regulatory compliance. Designed for compatibility with 37 #16 crimp contacts and a square-flange receptacle, it supports efficient panel assembly and traceable sourcing. For procurement teams, this translates into fewer supplier audits, predictable lead times, and fewer change orders due to certified parts. In industrial environments, the robust aluminum shell and defined operating range enable reliable performance from -40 °C to 100 °C.

Feature: 37-position arrangement for #16 crimp contacts enables high-density wiring. Business Impact: reduces harness length and wiring complexity, cutting assembly time and lowering risk of mis-termination. Application: ideal for machine control panels, servo drives, and distributed I/O enclosures in automated lines where space constraints and reliability targets are common. Feature: Aluminum shell with a 28-size shell delivers rugged mechanical protection while keeping weight low. Business Impact: lighter assemblies ease handling during installation and transport and improve vibration tolerance without sacrificing strength. Application: suitable for enclosure interfaces on robotics, conveyors, and industrial machines where corrosion resistance and durability matter. Feature: IP67 ingress protection and UL94 V0 fire-smoke certification, plus REACH and RoHS compliance. Business Impact: ensures safe operation in dusty, wet, or high-temperature environments while meeting global regulatory requirements, reducing certification time and the need for duplicate parts. Application: electrical cabinets, outdoor enclosures, and safety-critical equipment in heavy industry. Feature: Thread coupling and square flange receptacle orientation X provide secure mating and simple panel installation. Business Impact: minimizes unintentional disconnections in vibration-heavy setups and accelerates field terminations with consistent torque. Application: machine tools, packaging lines, and automated assembly cells where dependable coupling matters. Feature: 500 mating cycles rating and defined geometry support long service life and predictable maintenance planning. Business Impact: lowers replacement costs and downtime, enabling total cost of ownership improvements. Application: high-use control interfaces in continuous-operation plants.

FAQs
FER1B2821PX uses a square flange receptacle design with 37 cavities for #16 crimp contacts. This enables high-density wiring and simplified harness routing in control panels. When pairing with Souriau VGE1-FER1 family, ensure crimp terminals are sized for #16 contacts and that the mating interface is aligned to the X orientation for proper engagement. The 50.8 mm length/depth and 50.8 mm height support compact panel layouts without compromising reach or serviceability.
The connector features an aluminum shell and IP67 protection, delivering robust mechanical integrity and ingress resistance against dust and water. With a -40 °C to 100 °C operating range and 500 mating cycles, it maintains reliable electrical connections under temperature swings and frequent mating cycles typical of automation lines, packaging equipment, and robotics installations.
This part carries UL94 V0 flammability rating along with Fire & Smoke certification, and complies with REACH and RoHS requirements. These certifications facilitate regulatory approvals for machinery and electrical enclosures in many regions, reducing the need for additional certification testing and speeding project timelines.
Yes. The 37-contact, square flange receptacle design, IP67 sealing, and fire/smoke certification make it well-suited for machine safety circuits and control enclosures in harsh industrial settings. The threaded coupling provides secure mating, minimizing risk of disconnection during operation in vibration-prone environments.
With 500 mating cycles and a rugged aluminum shell, the FER1B2821PX offers a long service life that reduces replacement frequency and maintenance downtime. Combined with reliable IP67 protection and certified safety attributes, this translates to lower lifecycle costs and more predictable total cost of ownership for automated production lines.
