Fire and smoke certification ensures compliance with safety codes and reduces the risk of flame propagation in enclosures, translating to less downtime and safer installations in critical applications such as automated manufacturing lines and energy management systems. The IP67 rating and aluminium shell deliver robust durability in dusty and wet environments, enabling reliable operation in washdown areas and outdoor installations while protecting sensitive crimped #16 contacts. The 37-position configuration accommodates complex wiring harnesses, simplifying panel layouts and shortening assembly times, which lowers overall cost of ownership and accelerates project timelines. The bayonet connection provides a quick, secure mating method, improving field reliability and enabling faster maintenance cycles without compromising seal integrity. With 500 mating cycles, technicians gain confidence in long-term reliability for routine testing and hot-swapping in production lines. The square flange receptacle and W orientation support precise alignment and repeatable installation across Souriau VGE1-FER1 ecosystems, promoting compatibility and reducing the risk of mis-mating in dense panel environments. This design also aligns with RoHS and UL94 V0 standards, ensuring regulatory compliance across global supply chains and end-user facilities.
