Fire and smoke certification paired with IP67 ingress protection addresses safety and reliability requirements in hazardous environments. The bayonet coupling and UL94 V0 flammability rating unify compliance with harsh machine enclosures, reducing risk during audits and sudden events. In automation cabinets, control rooms, and process equipment, this foundation translates into fewer regulatory delays and safer operation under duress. High-density interconnection is enabled by 37 contacts in a 21-position layout, with #16 crimp contacts. The compact footprint reduces harness length, lowers wiring complexity, and minimizes panel footprint, enabling faster assembly and lower installation costs. Aluminum shell (size 28) keeps strength up while weight stays manageable at 82 g. The design supports up to 500 mating cycles, ensuring long service life in equipment subjected to frequent connect/disconnect cycles. Operating from -40 °C to 100 °C ensures reliable operation across indoor/outdoor installations. Together with RoHS/REACH compliance and a threaded, secure coupling, it provides reliable performance in demanding industrial environments. The straight plug orientation (Z) simplifies field installation, and compatibility with Souriau VGE1 segments streamlines system integration for automation and safety-critical applications. Engineers value this family for reduced downtime, easier regulatory approvals, and predictable maintenance in high-demand settings.

FAQs
FER1D2821PY is designed as part of the Eaton Souriau VGE1-FER1 family, sharing form, fit and function with existing VGE1 connectors. It uses a bayonet latch with a straight plug and a Z orientation, supports 37 #16 crimp contacts, and uses a 21-position layout. Its aluminum shell, 28 size, and IP67 rating ensure seamless mating with compatible housings while maintaining signal integrity in dense wiring.
FER1D2821PY is rated for -40 °C to 100 °C, enabling reliable operation across wide ambient conditions typical in automotive, industrial automation, and harsh environments. The aluminum shell and sealed contact interface help resist ingress and thermal stress, while the overall design minimizes enclosure cooling requirements. This temperature tolerance supports repeatable performance during startup, heavy-duty cycling, and long service life.
In industrial automation, the FER1D2821PY serves as a fire and smoke certified interconnect for safety-critical machinery, control cabinets, and process equipment. The 37-contact arrangement supports dense cabling and high data/power density, while IP67 and UL94 V0 ratings provide environmental resilience. Its rugged aluminum shell and 500 mating cycles support high-reliability, recurring field applications and reduced maintenance.
This connector meets multiple regulatory standards essential for industrial equipment: IP67 ingress protection; UL94 V0 flammability rating; RoHS and REACH compliance; and fire and smoke certification for safety-critical systems. The product's environmental and safety certifications help simplify compliance during system integration, reduce the need for separate approvals, and support long-term deployment in regulated sectors.
Installation considerations include using crimp contact tooling for 37 #16 contacts, secure thread coupling, and correct orientation (Z) to match mating half. Use compatible connector accessories ordered separately, as this unit specifies 'Not delivered, to be ordered separately.' The straight plug design and 55.3 mm length provide predictable routing in panel boxes and robotic enclosures, while the 500-cycle rating supports repeated field mating.
