Reliable power supply for automation devices with 7/8” connectors

binder offers its program for 7/8'' connection technology. Designed as 3-, 4- or 5-pin variants, connectors with screw clamp termination and pre-assembled cable connectors with straight or angled cable outlet are available. The products with reliable screw locking fulfil the conditions of protection degree IP67 – the over-moulded cables even IP68 – and have UL certification for use on the North American continent. With an ampacity of up to 13A in the 3-pin version and a rated voltage of 300V, or 600V according to UL guidelines, the 7/8'' circular connectors are appropriate for power applications in automation technology.

Important fields of application for the flexible 7/8'' technology can be process, factory, and warehouse automation, for example, in the packaging or food industry. Here it is a proven element in the power supply of sensors, actuators, and various fieldbus devices. Practical examples include drive or lighting technology and the electrical connection of heating devices. The power supply of 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 7/8'' connectors from the company are protected to IP67/IP68 against the effects of particles and moisture, offering durable, industrial-grade components for the power supply.

For power supply applications in the automation environment, the company provides assorted ready-to-connect, pre-assembled and over-moulded cables: in straight and angled versions, in different lengths and with stainless-steel cable screw connections for use in corrosive ambient conditions. Field-wireable products, on the other hand, permit greater flexibility in selecting cable materials and lengths. The screw termination inside provides a cost-efficient, detachable connection. Cables with diameters from 6mm to 12mm can be connected; possible wire gauges range up to 2.5mm². Gold-plated contacts and stainless-steel variants provide a long mechanical service life at low contact resistances, particularly for use in industrial environments.

Users who need 7/8'' technology for installation in device housings can select from its flange connectors with assorted thread designs. On the termination side, there is a selection of pre-assembled wires in varied lengths and dip solder contacts for mounting on a printed circuit board. The portfolio also expands to products for the CAN-based DeviceNet fieldbus – including clever additions such as the 870-series T distributors in different pin counts, which supply two loads simultaneously from one source.
