Feature → Business Impact → Application: The FER1B2821P0 uses a square flange receptacle with thread coupling, enabling quick, secure mounting in panel cutouts while maintaining precise alignment for 37 #16 crimp contacts. This translates to faster wiring, reduced rework, and improved seal integrity in harsh environments such as manufacturing lines and industrial automation cabinets. Feature → Business Impact → Application: Aluminium shell provides metal fatigue resistance and rigid structural integrity, supporting IP67 sealing and long-term reliability in exposure to dust, moisture, and temperature cycling. This is critical for rail control panels, machine enclosures, and outdoor installations where ingress protection and durability matter. Feature → Business Impact → Application: Operating temperature range from -40 °C to 100 °C and 500 mating cycles deliver predictable performance under thermal stress and lifecycle demands, minimizing field failures and maintenance costs in infrequent yet high-stress startup/shutdown cycles. Feature → Business Impact → Application: Fire & Smoke certification, UL94 V0, RoHS, and REACH compliance reduce regulatory risk and simplify supplier qualification for safety-critical applications such as power distribution, safety interfaces, and emergency control networks. Feature → Business Impact → Application: 21-layout cavity design with 37 contacts supports scalable system expansion, allowing engineers to plan future wiring needs without replacing connectors, ideal for modular automation architectures and retrofits. Feature → Business Impact → Application: Compatibility with Souriau VGE1 family mating patterns ensures interchangeability within existing harnesses and reduced BOM proliferation, easing procurement and inventory management in OEM integration projects.

FAQs
Installation uses a square flange receptacle with thread coupling, mounted in a panel cutout sized to the 28 shell size. Plan for panel thickness compatible with the 50.8 mm length, secure with appropriate fasteners, and ensure proper gasket seating to maintain IP67 sealing. Use crimp contacts sized for 37 #16 conductors and verify mating alignment with the Souriau VGE1 family mating pattern.
The connector employs crimp contact delivery for 37 cavities, with IP67 protection, operating from -40 °C to 100 °C, and a 500 mating cycle life. The aluminium shell provides mechanical strength, while RoHS and REACH compliance address environmental and regulatory requirements in industrial deployments.
Yes. With IP67 sealing, UL94 V0 flammability, fire & smoke certification, and a rugged aluminium shell, FER1B2821P0 is well suited for rail, rail-adjacent equipment, and heavy machinery control panels where ingress protection and flame resistance are critical.
The connector carries Fire & Smoke certification, UL94 V0 flammability, RoHS, and REACH compliance. These certifications reduce regulatory risk, simplify supplier qualification, and help you meet safety, environmental, and industry-specific requirements in automotive, aerospace, and industrial automation projects.
With 500 mating cycles and robust sealing, the connector minimizes field failures and routine maintenance. The durable aluminium shell and corrosion-resistance features lower replacement costs, while dependable mating reduces downtime and extends system uptime in critical automation lines, delivering measurable total cost of ownership advantages.
