One Standard, All Possibilities.

Smart Sensor Solutions in Economical Miniature Design

The 1K format simplifies the use of smart sensors in standard industrial automation applications. The compact format as well as a consistent design, assembly and operating concept reduce the effort required in design, maintenance and purchasing. All variants are based on a common platform principle with IO-Link 1.1 and include photoelectronic and ultrasound-based sensors. The wide selection of standardized functional principles makes it easy to select the right sensor for a wide range of applications and to integrate it cost-effectively – with a uniform electrical connection and identical mounting hole pattern.

Your Advantages
1. More efficient construction thanks to uniform miniature design
2. Fast initial startup and diagnosis thanks to consistent IO-Link interface
3. Easy standardization and sensor exchange through multiple functional principles in one platform

The 1K Platform: One Standard, Many Benefits

The 1K format combines different sensor technologies on a common platform. Uniform mechanical interfaces – such as housing dimensions, fastening points and connection position – enable the unique definition of an installation space that can be used for various detection tasks. Depending on the application, only the appropriate functional principle is selected within the platform.

This results in clear advantages for design, operation and purchasing:

Through-beam sensors

Go directly to section

In reflex mode, the emitter and receiver are located in a common housing. The transmitted signal hits the object, is reflected by it and sent back to the receiver. Detection is based on the returning signal, which allows objects to be detected without an additional reflector or separate receiver.

In the case of the retro-reflex sensor principle, the emitter and the receiver are located in one housing. The transmitted signal is fed back to the receiver by an opposite reflector. If an object enters between the sensor and the reflector, the signal reflected back is interrupted or attenuated. Based on this change, the sensor detects the presence of the object.

With the through-beam barrier principle, the emitter and receiver are arranged opposite each other in separate housings. If an object passes through the space between the two components, the signal is interrupted or weakened. Based on this change, the sensor detects the presence of the object.

Through-Beam Sensors

Through-beam sensors detect objects by interrupting the light beam between the emitter and receiver. They enable large ranges and operate at high switching frequencies. They are also insensitive to contamination.

• Signal value and switching threshold in digits
• Flexible parameterization of output logic and switching function
• Graphical signal analysis in wTeach2 with display of signal value and switching threshold

Ultrasonic Through-Beam Sensors

Ultrasonic through-beam barriers are used for applications with a larger range. They operate in through-beam mode with ultrasound and enable reliable object detection at high switching frequencies. U1KT ultrasonic distance sensors can be used in both reflex and through-beam mode

• Ultrasonic through-beam sensors
• Signal value and switching threshold in digits
• Data storage and extended parameterization as standard
