How does TIOL111 (IO-Link device transceiver) enable IO-Link communication in space constrained connected ultrasonic distance sensors as shown in reference design TIDA-01386?

  • TIDA-01386 is a TI Reference Design featuring an ultrasonic distance sensor that fits in M12 housing due to its high integration and an optimized layout. The design offers an IO-Link interface to communicate with the system control, which makes it industry 4.0 ready.  The purpose of ultrasonic sensors is to detect or measure distances of an object independently from their color, transparency, or surface characteristics and from the surrounding environment. Ultrasonic sensors are able to function in harsh environments such as factories and process plants.

    TIOL111 is a transceiver implementing the IO-Link interface for industrial bidirectional, point-to-point communication. When the device is connected to an IO-Link master through a three-wire interface, the master can initiate communication and exchange data with the remote node while the TIOL111 acts as a complete physical layer for the communication

    The TIOL111 comes in a very small form factor allowing the distance sensor to be only 8.9 mm in width. Thus it fits in standard M12 housing while still being capable of withstanding up to 1.2 kV (500 Ω) of IEC 61000-4-5 surge. The Proximity Switch Reference Design TIDA-01239 takes it even further demonstrating a possible width of only 3.5 mm while still being capable of withstanding up to 1.2 kV (500 Ω) of IEC 61000-4-5 surge.

    You can download the design files (BOM, Schematic, Gerber) for this reference design from the TIDA-01386 folder.
