IO-Link - The standard for Industry 4.0

IO-Link illustration


Sensors are being used in more and more complex tasks in the course of the 4th industrial revolution. To make full use of the sensor’s performance capacity, IO-Link now enables communication down to the lowest field level.


Product overview

Distance sensors for long scanning ranges
FT 55-RLAP(2)

FT 55-RLAP(2)

Distance sensors of type FT 55-RLAP(2) that function according to the time-of-flight principle measure distances of up to 5m with utmost precision. They supply a signal either via the analogue output (4 to 20 mA/0 to 10 V) or via IO-Link, and also have an additional switching output with a switching window function, which can be adjusted independently of the analog measuring range. The sensor can be used for example for coil diameter control, robot positioning or the measurement of fill levels and stacking heights.
Color sensors for long scanning ranges
FT 55-CM-4

FT 55-CM-4

The FT 55-CM color sensor offers a scope of functions and level of user-comfort that are unsurpassed in its performance class. The wide operating range – independent of distance – combined with the flexible color detection feature gives a diverse range of applications. The large integrated LCD display and remote configuration via SensoVisual and IO-Link set new standards in ease of use and connectivity. This unique combination of characteristics makes the sensor ideally suited for challenging color detection and sorting tasks, for example in machine construction and in the automotive, plastics, pharmaceutical or packaging industries.
Photoelectric sensors for long scanning ranges


Proximity sensor versions of type FT 55-RLHP2 with IO-Link are optionally available with one or two digital switching outputs and offer reliable object detection at long distances (up to 5 m on white and 3 m on black). Reliable detection of the target object is guaranteed even with interfering backgrounds, regardless of colour, shape, structure and alignment. Time-of-flight proximity switches are used for example to check the assembly of rubber and plastic components in automotive manufacturing, to check the occupancy of storage bays in high bay warehouses or to check the position of round timber.


The SensoIO is the ideal tool for development and service. Settings can be carried out quickly and easily on a PC or laptop with the aid of the USB-IO-Link master.
