Binder explains how innovative design and careful material selection help ensure connectors are providing reliability in tough and demanding conditions.
In recent years, the design of heavy outdoor machinery and equipment has seen a move from mechanical/ hydraulic components to computer-controlled electronics and telematics systems, increasing demand for harsh environment connectors. Connectors provide vital links for power and signal transmission in outdoor and harsh conditions where reliability is critical.
Connectors must withstand extreme temperatures, humidity, chemical exposure, dust, vibration and shock in industries ranging from industrial automation and agriculture to renewable energy and marine.
Diverse types of harsh environment connectors are designed to meet specific applications. Binder specialises in circular connectors, known for their ease of connection and frequent use in industrial settings. Other types include rectangular connectors (high density); fibre optic connectors (high-speed transmission); and coaxial connectors used in communication systems.
Durability is crucial, requiring robust materials and construction to withstand physical and environmental stresses. Stainless steel, aluminium and brass offer strength and corrosion resistance, while PEEK and PTFE polymers provide excellent chemical resistance and mechanical properties. Rubber and silicone are used for their flexibility and sealing capabilities, ensuring effective ingress protection and durability.
High IP ratings (IP67, IP68 or IP69K) are important to protect against water, dust and other contaminants. Connectors must provide high resistance to chemicals, damp heat and temperatures from -40 to 100°C and mechanical impacts.
In explosive environments, connectors must ensure safety, durability, performance and compliance. These connectors are often installed in areas where flammable gases, vapours or liquids might be present under abnormal conditions. Additional standards focus on material resistance to salinity, enabling connectors to withstand saline environments like saltwater.
As a specialist in circular connectivity, binder provides harsh environment connectivity solutions designed to endure extreme conditions. The HEC series 696 (Harsh Environment Connector) is the first choice for robust outdoor connectors. Available in square flange and cable versions (with an integrated protective conduit) this power connector offers protection to IP67 and to IP69K when mated. It is UV-resistant and has VDE and UL approvals. The high mechanical load capacity is demonstrated by over 500 mating cycles for the 12-pole version and over 1,000 mating cycles for the five and eight-pole versions.
Rapid growth in use of sensors in outdoor harsh environments means go-to industrial standard M12 connectors are increasingly used for outdoor applications. Given binder’s long history as a market leading manufacturer of M12 for indoor applications, it is no surprise there is an M12 connectors specifically designed for outdoor use in harsh conditions. These connectors feature stainless steel locking mechanisms, with options for stainless steel or UV-resistant plastic housings. They offer protection to IP69K.
A distinctive feature of binder’s M12 connectors for outdoor applications is the protective cap, which ensures resistance to dust and water when unmated. The connectors are also temperature and chemical resistant.
