binder offers its program for 7/8” connectors. Designed in 3, 4 or 5 pin variants, connectors with screw terminals and pre-assembled cable connectors with straight or angled cable outlet are available. Products with reliable screw locking meet the requirements for degree of protection IP67 – molded cables even IP68 – and have UL certification for use on the North American continent. With a current of up to 13 A in the 3-pin version and a nominal voltage of 300 V or 600 V according to UL guidelines, the 7/8” circular connectors are suitable for power applications in automation technology.

Important areas of application for 7/8” flexible technology can be process, plant and warehouse automation, for example in the packaging or food industry. Here it is a proven element in the supply of sensors, actuators and various fieldbus devices. Practical examples include drive or lighting technology and the electrical connection of heaters. Powering active distribution boxes, often called sensor-actuator boxes, using 7/8” connectors is very common. The main purpose of these devices is to simplify the wiring of complex field installations. The company’s 7/8” connectors are protected to IP67/IP68 against the effects of particles and moisture, providing durable, industrial-grade power supply components.

For power supply applications in the automation environment, the company offers an assortment of ready-to-connect, pre-assembled and potted cables: in straight and angled versions, in various lengths and with cable screw connections stainless steel for use in corrosive environments. conditions. Field-wired products, on the other hand, allow greater flexibility in the choice of materials and cable lengths. The screw termination inside provides a detachable and cost-effective connection. Cables with a diameter of 6 mm to 12 mm can be connected; possible wire gauges are up to 2.5 mm². Gold-plated contacts and stainless steel variants provide long mechanical life at low contact resistances, especially for use in industrial settings.

Users who require 7/8” technology for installation in device enclosures can choose from its flange connectors with matching thread designs. On the termination side there is a selection of pre-assembled leads of various lengths and dip solder contacts for mounting on a printed circuit board. The portfolio also extends to products for the CAN-based DeviceNet fieldbus – including smart additions such as the 870 series T Splitters in various pin counts, which power two loads simultaneously from one source.
