Applications
- Maintenance technician replacing a failed cordset on a production line sensor - routes the cable, seats the Microfast connector, and terminates the bare leads into the terminal block before bringing the machine back online
- Machine builder wiring proximity sensors or limit switches during new panel assembly - selects the 4-meter length to reach from the sensor mount to the control enclosure without a junction
- Automation integrator commissioning a conveyor or packaging system - installs the cordset on a device with a compatible 1/2"-20 UNF Microfast male port and pulls the flying leads into the PLC I/O module
- Facility electrician keeping a spare on the shelf for fast swap-out when a harsh-environment sensor connection fails due to wash-down or chemical exposure
Frequently Asked Questions
What connector does the device side need to mate with this cordset?
The cordset has a 3-pin 1/2"-20 UNF Microfast straight female connector. The mating device must have a compatible 3-pin 1/2"-20 UNF Microfast male connector. It will not fit M12 Eurofast, M8, or 7/8" Minifast connectors.
What is included in the sale?
The cordset only - no accessories. Flying leads are bare tinned wire; no ferrules or terminals are included.
Does the cable need conduit or additional protection in wet or wash-down environments?
The TPU jacket carries IP67, IP68, and IP69K ratings along with NEMA 4 and NEMA 6P ratings, which cover submersion and high-pressure wash-down. No additional conduit is required for those conditions, though installation practices for your specific environment should be followed.
Are there other lengths or configurations available in this series?
Yes. Turck makes shorter lengths (e.g., 2-meter KB 3T-2/S90), right-angle female versions (WKB 3T-4/S90), and double-ended cordsets with a connector on both ends. This listing is for the 4-meter straight female to bare leads version only.
A factory-assembled cordset with IP69K ratings and a Made in USA label sitting unused on a shelf - someone specified this part for good reason. Now it goes to the job it was built for.
