Fire and smoke certified design combined with IP67 sealing reduces the risk of fire propagation and ingress in harsh environments, stabilizing uptime and safety in control panels and outdoors. This translates to lower maintenance costs and fewer field failures, especially in crowded electrical enclosures where space is at a premium. The 37 contact positions in a 21‑cavity layout enables high wiring density without sacrificing signal integrity, simplifying harness routing and reducing panel height. Aluminium shell offers a strong yet lightweight enclosure, improving handling during installation and transport while resisting corrosion in challenging environments. Thread coupling with Z orientation minimizes misalignment during mating, expediting installation and reducing rework on the shop floor. With a wide operating temperature range from -40 °C to 100 °C and 500 mating cycles, the solution supports long service life in rail, automation, and process industries, while remaining compatible with standard crimp contacts (#16). The 55.3 mm length/depth and 48.1 mm width provide predictable, repeatable fit in dense cabinet architectures, supporting scalable designs for growing automation demands.

FAQs
Install by pairing with the mating VGE1-FER1 counterpart, ensure the shell insulator is prepared for connection (note: insulator not installed in the shell per spec), and use crimp contacts #16 as specified. Align orientation to Z, engage the thread coupling, and verify IP67 sealing after mating. Connector accessory options are not delivered and must be ordered separately.
Yes. The FER1D2821S0 is rated IP67, providing effective protection against dust and water ingress. This makes it suitable for outdoor installations, damp factories, and harsh industrial settings where washdowns or exposure to contaminants are common, helping maintain electrical reliability.
Industries such as industrial automation, rail/transport signaling, machinery harnessing, and process control benefit from high-density 37‑position connectivity in a rugged, flame‑retardant package. The design supports compact harness routing, reliable crimp terminations, and regulatory compliance for safety-critical installations.
The connector carries fire and smoke certification, RoHS and REACH compliance, and UL94 V0 flammability. These certifications matter for safety, environmental responsibility, and regulatory alignment, enabling easier procurement, risk mitigation in fire-prone environments, and compatibility with industry standards used in aerospace, rail, and industrial automation.
The FER1D2821S0 supports up to 500 mating cycles, offering a predictable lifecycle for mission-critical harnesses. For maintenance, inspect mating interfaces and shell integrity regularly, replace damaged components promptly, and ensure mating surfaces are clean to maintain IP67 performance and electrical continuity in harsh environments.
