Fire & Smoke certified and IP67-rated design ensures regulatory compliance and field reliability, reducing risk of enclosure failures and costly downtime. The 37-position layout supports flexible power and signal distribution for automation racks and robotics, delivering measurable efficiency gains and easier harness management with a single, rugged solution. Aluminium shell with a 28-size profile keeps weight low while withstanding industrial environments; thread coupling provides secure mating even in vibration-prone equipment, supporting faster installation and maintenance workflows. Operating from -40 °C to 100 °C, and with a 500-mating-cycle rating, this plug maintains performance across temperature swings and repeated connections, lowering lifecycle costs and boosting ROI in military, aerospace, and heavy industry. Certifications such as RoHS, REACH, and UL94 V0 help satisfy compliance programs and customer requirements, while compatibility with Souriau VGE1-FER1 ecosystems simplifies component sourcing and spare-part planning for OEMs and integrators.

FAQs
FER1D2821SN is designed to complement the Souriau VGE1-FER1 series, sharing the same bayonet coupling philosophy, 37 contact positions, and crimp #16 contacts. It maintains the N orientation and straight plug configuration, enabling straightforward mating with compatible receptacles. When integrating, verify shell size 28 and aluminium construction to ensure mechanical fit and thermal performance within chassis designed for rugged industrial environments.
The connector supports up to 500 mating cycles, supporting repeated installation and maintenance without performance degradation. It operates from -40 °C to 100 °C, ensuring reliable performance across extreme cold and hot environments typical of manufacturing floors, outdoor enclosures, and machinery bays.
Yes. With IP67 ingress protection and a rugged aluminium shell, the Fer1D2821SN is well-suited for outdoor robotics, enclosures, and exposed industrial installations. Its fire and smoke certification (UL94 V0) and RoHS/REACH compliance further support safety and environmental requirements in field deployments where moisture, dust, and heat are concerns.
FER1D2821SN meets IP67 for moisture and dust resistance, UL94 V0 for flame retardancy, and RoHS/REACH environmental standards. These certifications help users pass regulatory audits, ensure safer operation in hazardous zones, and reduce risk of non-compliance penalties, while supporting reliability in telematics, industrial automation, and machinery enclosures.
The 500 mating cycles, corrosion-resistant aluminium shell, and IP67 sealing translate to lower replacement rates and less downtime, delivering a favorable total cost of ownership. Coupled with straightforward crimp assembly and compatibility with the VGE1-FER1 family, maintenance teams benefit from faster field servicing and predictable spare-part planning, boosting overall return on investment in capital-intensive automation environments.
