Turck NIC contactless inductive couplers feature IO-Link

Turck Australia announces the launch of the new NIC contactless inductive coupler series suitable for use in data and energy transmission.

A wear-free alternative to classic connectivity solutions, the new NIC series is capable of transferring up to 12 Watts and 0.5 amps of power across an air gap of 7mm. Featuring a tolerated angle offset up to 15 degrees and a parallel offset up to 5mm, the couplers can also be fitted in restricted and non-standard mounting locations while still allowing for full power transfer.

The new NIC series contactless inductive couplers transfer two PNP switch signals. If the primary unit is connected to an IO-Link master, signals can be transferred bi-directionally from IO-Link-capable sensors and signals from IO-Link-capable DI/DO junction modules can also be controlled. When using a primary unit with an integrated IO-Link master and a 12-pole plug connector, and with a TBIL- M1-16DIP I/O hub on the secondary side, up to eight switching signals can be transferred, which can be used on the primary side as separate outputs.

A diagnostic function in the contactless inductive coupler detects the presence of the secondary unit as well as any metal objects in the air gap, which may otherwise weaken a transfer.


The new NIC series contactless inductive couplers offer an ideal solution for the wear problems occurring with plug and wiper contacts exposed to severe stress. In overhead conveyor systems or on rollers, the inductive couplers offer a maintenance-free alternative to the wear-intensive slip ring.

The speed of the system is ideal for use in applications with high cycle rates such as tool changer robots or rotary indexing tables: The secondary unit is operational within 10 milliseconds and supports Dynamic Pairing, i.e. the coupling of any primary and secondary units. The application specific tag in the IO-Link protocol makes it possible to identify the relevant IO-Link device precisely, which means it is possible to replace the use of additional identification equipment such as RFID for a tool or skid change application.
