IO-Link
IO-Link is a point-to-point digital communication standard between sensor/actuator and controller, transmitted over standard 3- or 4-wire cabling. Devices in this category cover pressure, distance, and discrete signal conversion, plus multi-channel hubs that aggregate binary inputs into a single IO-Link master port. Typical use is parameterisation, diagnostics, and process-value transmission in factory automation and hydraulics.
The assortment includes pressure transmitters, distance sensors, signal converters, and IO-link hubs, with manufacturers such as IPF and Turck. Distance ranges cover 16 mm, 20 mm, 40 mm, 150 mm, 300 mm, and 600 mm.
Supply voltage is mostly the wide-range 10…30 VDC input, with 12…30 VDC and 18…30 VDC variants for higher-voltage process bus environments. Connections use 3-wire or 4-wire cabling.
Switching frequencies span discrete event applications at 20 Hz and 200 Hz up to fast detection at 3000 Hz and 5000 Hz. Ambient temperature most often runs -25 …+70 °C, with extended cold-store variants at -40 …+70 °C.
Pigtail variants are stocked at 0.15 m, 0.2 m, and 0.3 m for M12 connector use, fixed cables at 2 m and [5 m](/en/io-link?filters=%5B%7B%22key%22%3A%22EF000536%22%2C%22values%22%3A%5B%7B%22min%22%3A5%2C%22max%22%3A
