FAQs
FER1D2821PX is designed to be compatible with Eaton Souriau VGE1-FER1 series interconnects. For straightforward field assembly, align the straight plug to the mating receptacle, verify the 21-position layout, and engage the thread coupling until a full engagement is felt. Ensure crimp contacts are correctly terminated to #16 wires and that the housing seals are clean and undamaged to preserve IP67 integrity. If using accessory options, procure them separately to maintain certification validity.
Key specs include 37 contacts for #16 crimp terminals, 500 mating cycles, IP67 protection, and an operating temperature from -40 to 100 °C. The aluminium shell provides robust mechanical protection, while the crimp contact design ensures consistent electrical continuity. The thread coupling and 21-layout contribute to repeatable, vibration-resistant mating. Together, these features support stable signal and power transfer in demanding environments.
Yes. The FER1D2821PX is designed for harsh environments with IP67 sealing and an aluminium shell, offering resistance to dust, water ingress, and exposure to temperature extremes. Its UL94 V0 fire rating and RoHS/REACH compliance also support safety and regulatory requirements in outdoor industrial automation, power distribution, and marine or offshore applications where reliability is critical.
The FER1D2821PX carries UL94 V0 flammability ratings for fire safety, along with RoHS and REACH compliance for restricted substances and environmental responsibility. It is also rated IP67 for ingress protection, and provides a rugged industrial grade suitable for long-term field use. These certifications help meet industry and regulatory requirements across manufacturing, energy, and process sectors.
The connector's 500 mating cycles and corrosion-resistant aluminium shell support long maintenance intervals, reducing replacement frequency and downtime. Its IP67 sealing minimizes environmental damage in harsh production lines, contributing to lower warranty and service costs. Although initial procurement may be higher, total cost of ownership improves through reliability, standardized interconnects, and reduced field maintenance across automation and power systems.
