Fire & Smoke certified design reduces compliance risk while delivering reliable performance in environments with heat and flame exposure, translating to safer installations and reduced QA overhead in critical systems. The IP67 rating shields the 37 cavity receptacle from dust and water ingress, enabling uninterrupted operation in manufacturing lines, rail, and outdoor equipment. A compact aluminium shell at size 28 keeps weight low without sacrificing durability, improving overall machine efficiency and ease of handling during installation and maintenance. The 37 #16 crimp contacts support dense, high-current or signal routing in a single connector, with up to 500 mating cycles providing predictable lifecycle costs and reduced spare-part stock. Thread coupling and square flange receptacle geometry simplify mounting and alignment, speeding assembly while ensuring robust vibration resistance and seal integrity. With operating temperatures from -40 °C to 100 °C and a 500-hour salt spray rating, this connector is ready for harsh environments, from automated warehouses to outdoor machinery, while RoHS and REACH compliance address sustainability requirements. Connector accessories are available separately, enabling tailored configurations for specific equipment and field-serviceability.
