Eaton FER1B2821PY Bayonet Receptacle - Fire/Smoke Certified
Part Number: FER1B2821PY
Quick Summary
The Eaton FER1B2821PY Bayonet Receptacle enables reliable power connections for safety-critical fire and smoke applications. Engineers often struggle with slow installs and uncertain sealing when upgrading to fire-rated connectors. This part supports IP67 protection, RoHS compliance, and UL94 V0 fire safety, enabling global deployments. By combining robust mechanicals with 37 #16 crimp contacts and a square-flange profile, it reduces assembly time and test cycles. In practice, the aluminum shell and 28-size housing deliver lightweight, durable performance in control panels and machine doors. With 500 mating cycles and operating temperatures from -40 to 100 C, maintenance windows lengthen and total cost of ownership improves.

Feature → Business Impact → Application: Fire and smoke certification across the VGE1-FER1 family ensures compliance with global safety standards, reducing risk in mission-critical machinery and enabling faster time-to-production in safety-sensitive environments. This translates to lower rework costs and enhanced customer confidence in regulated industries such as energy and manufacturing. Feature → 37 contact positions for #16 crimp contacts provides high-density power and signal distribution within a compact footprint, lowering panel space requirements while maintaining reliable mating performance, ideal for control cabinets and machine frames. Feature → Aluminum shell with a size 28 housing yields a lightweight yet durable enclosure, improving installation ergonomics and reducing chassis stress in remote or vibration-prone locations. Feature → Thread coupling and square flange receptacle orientation Z support robust, vibration-resistant mating in harsh environments, reducing maintenance visits and improving uptime in packaging lines and automated cells. Feature → IP67 protection, -40 to 100 °C operating range, and 500 mating cycles deliver long-term reliability, which lowers spare-part inventories and extends service life in outdoor or industrial settings. Feature → Salt spray resistance (500 hours) and RoHS/REACH compliance ensure longevity in corrosive environments and simplify regulatory compliance for global deployments, from automotive assembly to power distribution. Feature → Non-delivered contact delivery and accessory options can be sourced separately, allowing tailored configurations without carrying unneeded stock, improving portioned procurement and reducing total-cost-of-ownership concerns.

FAQs
FER1B2821PY is designed as a square flange receptacle for the Souriau VGE1-FER1 family and uses a thread-coupling bayonet mating interface. It supports 37 #16 crimp contacts and a Z orientation, making it compatible with standard control-panel backplanes and mating with corresponding Souriau connectors. Ensure the panel cutout matches the 28 shell size and that the mating counterpart is the FER1 bayonet plug to achieve IP67 sealing.
This connector is IP67 rated for ingress protection, operates from -40 °C to 100 °C, and carries RoHS and REACH compliance with a UL94 V0 flame rating. Salt spray endurance is specified at 500 hours, and it supports up to 500 mating cycles, supporting long-term reliability in harsh industrial environments.
Yes. The FER1B2821PY is fire and smoke certified as part of the VGE1-FER1 series, designed to maintain circuit integrity in fire-rated installations. This makes it appropriate for safety-critical equipment in automation, energy, and transportation sectors where fire safety certification and dependable performance are required.
The receptacle features a 50.8 mm length/depth, 50.8 mm height, and 48 mm width. It uses an aluminum shell with shell size 28 and weighs 92 g. These dimensions provide a compact yet sturdy footprint suitable for tight control-panel layouts while preserving robust mechanical strength.
Plan for separate procurement of connector accessories and contact deliveries, as FER1B2821PY specifies 'Not delivered' for these elements. Ensure you have compatible #16 crimp contacts and the mating plug from the same Souriau VGE1-FER1 family. Verify the panel cutout aligns with shell size 28, and confirm environmental sealing with proper gaskets to preserve IP67 performance in outdoor or damp locations.
