Product Overview
Murrelektronik article number 7000-78261-0000000 (also designated 27671) is a heavy-duty 7/8-inch 5-pole female connector built for industrial automation and sensor-actuator field wiring. The 90-degree right-angle body allows clean cable runs in tight clearances where straight connectors cause strain. Screw-clamp terminals and an integrated compression gland make installation and servicing direct, requiring no specialized crimp tooling.
Key Features
- Standard 7/8-inch (7/8-16 UN) threaded female metal coupling nut
- 5-pole socket configuration (4 circuit contacts plus dedicated protective earth PE position)
- 90-degree right-angle orientation for low-profile cable exit
- Field-wireable screw-clamp terminals accommodating 0.14 mm² to 1.5 mm² wire gauge
- Cable gland sealing round outer jacket diameters from 6.0 mm to 8.0 mm
- Rated for up to 9 A and 600 V AC (UL) / 250 V AC/DC (IEC)
- IP67 ingress protection against dust and liquid washdown when properly mated
- Operating temperature range of -25 °C to +85 °C
Applications
- Terminating field bus drops and auxiliary power lines on industrial automation machinery.
- Routing power and sensor wiring in confined machine frames where bend radius is constrained.
- Building modular power disconnects for CNC machinery, conveyor systems, and robotic cells.
- Wiring rugged high-current interconnects for custom automation builds and workshop equipment.
Frequently Asked Questions
What mating thread does this connector use?
It features a standard 7/8-inch 16 UN female threaded coupling ring designed to mate securely with standard 7/8-inch male plugs and panel receptacles.
What wire sizes and cable diameters fit the terminals and gland?
The screw terminals take conductor sizes from 0.14 mm² to 1.5 mm², and the compression gland accommodates round cables with an outer jacket diameter between 6.0 mm and 8.0 mm.
What is the contact arrangement?
This female connector has 5 contact positions arranged as four standard circuit poles plus one ground contact marked for protective earth. Order more and each piece costs less - the price-break table on this page spells it out.
Industrial machinery does not wait around for awkward bends or loose wires. A solid right-angle connector puts the turn right where the conduit needs it, seals tight, and keeps the line moving.
