Construction of the touch sensors: Can the stainless steel symbol discs also be mounted on plastic sensors?

This is possible, however, the data sheet specifications refer to the plastic sensors in combination with the plastic symbol discs. A: Stainless steel device B: Plastic device with symbol disc C: Plastic device with transparent symbol disc and symbol sticker 1: Easy mount nut 2: Sealing ring (outer) 3: Touch sensor 4: Sealing ring (inner) 5: Symbol sticker 6: Plastic symbol disc (with and without symbol) 7: Symbol disc for stainless steel devices 8: Stainless steel ring

How do I configure the sensor to suppress splash water or dirt?

You can configure 3 different sensitivity and environment settings via IO-Link:

Are the touch sensors FDA compliant?

If the existing seal is replaced by the optionally available seal E12840 , the KTE (front) is compliant with FDA.

What’s new compared to the previous generation?

The new KTE touch sensors have a more robust housing and are absolutely ingress-resistant and yet very flexible thanks to the interchangeable symbol discs. The symbol discs are easy to replace irrespective of the symbol or material. Up to 5 colours can be triggered via 2 digital inputs even without IO-Link. The sensitivity of the sensors can be adjusted to damp or dirty environments.

What do I need to consider when mounting the sensor?

The symbol discs are not included and must be ordered separately. The stainless steel symbol discs also fit on the plastic KTEs, however, the sensor adjustments were made based on the characteristics of equivalent materials. In humid environments, the sensor should be used with a symbol disc of the same material. The KTE101 sensor is supplied with a transparent symbol disc and various stickers. With this product, the orientation of the connector is not fixed. If the nut is too tight to be opened by hand, it can also be loosened with a size-27 open-end wrench:

Capacitive touch sensors built to last

Touch sensors are used in a wide range of applications, from opening or closing gates to resetting systems after a stop. The new Eternity touch sensors make plant and machine operation even easier thanks to their versatile features:

The RGB LEDs on the touch sensors provide information about the plant condition. Up to five colours can be easily defined via IO-Link.
The new series of KTE touch sensors is complemented by the KTV signal lamps in the same design, providing the user with a uniform user interface.
Thanks to their precise finger detection function, the touch sensors are operated intuitively with just a light touch, improving workplace ergonomics.
The sensitivity of the sensors can be adjusted to environmental conditions, allowing effective suppression of splash water or deposits.

Product benefits of KTE and KTV

Specially designed nut for easy manual mounting
The specially developed crown design allows firm tightening of the nut by hand or fingertips even in confined spaces.

Suppression of deposits or splash water
The sensitivity of the sensing surface can be adjusted to the environmental conditions to prevent deposits or splash water from triggering faulty switching operations.

Application-specific sensitivity setting
The sensor can be configured for operation with or without gloves.

Ergonomic working
The capacitive finger recognition function allows actuation without force or pressure. The sensor can be operated with just a light touch of a finger, easing the burden on fingers and wrists.

Customisable for any application
The adjustable colours of the sensors and lamps and the interchangeable symbol discs offer maximum flexibility and allow unambiguous function assignment of the sensor in any application.

Easy cleaning
The sensors are easy to clean thanks to their smooth surface. Providing wear-free switching and a hermetically sealed housing, they are built to last.

One sensor for all applications!
The sensors can be set as switches, buttons or latching switches.

Manual control of touch sensors

Control of the digital inputs as a clickable animation

The animation shows how the digital inputs of the KTE touch sensors can be controlled without IO-Link using, for example, the Y cables EVC847 and EVC848:
Clicking on touch sensor 2 and 3 sets their output to control a colour change of touch sensor 1. Clicking on “Master sensor” 1 overwrites the signals present at the inputs.
