Touch Sensor – Finger-actuated button
— DC | Pre-wired or quick-disconnect, mechanical start/stop buttons are prone to wear and tear. In contrast, ifm’s cylindrical touch sensors respond to a light touch and therefore do not wear out, ensuring a long service life in the application.

IFM KT6000/6300 Series Capacitive Proximity Sensor Switch

Technical Features

Uses dynamic and static sensing principles, enabling it to reliably replace mechanical and photoelectric touch sensors.

Triggered by a light touch from a single finger.

The housing is impact-resistant, wear-resistant, and waterproof (Protection rating IP69K).

The dynamic sensing principle allows the sensor to ignore material build-up on the sensing face.

Numerous different settings can be configured via IO-Link, such as color, normally open/normally closed operation, or triggering method.

Benefits Introduce In Detail

Cylindrical Capacitive Touch Sensor for Starting/Stopping Machines with a Light Touch

New! The KT series multi-color touch sensors are suitable for processes such as starting and stopping machines and for assembly lines. Compared to mechanical pushbuttons, the KT series sensors have many advantages. They use the capacitive sensing principle, are electronic sensors, and have no moving parts that could wear out. The entire device features a fully sealed design with a protection rating up to IP69K, which makes it oil-proof and allows it to ignore the effects of material build-up on the sensing face. The space occupied by a KT series sensor is roughly half that of a mechanical pushbutton, which can free up valuable space on the back of a control panel.

One Sensor for All Applications via IO-Link

The KT series can be easily adapted to the needs of any application. By using IO-Link, the normally open/normally closed functions and colors for different operating states can be set within minutes. Additionally, the following output modes can be selected:

Dynamic output: Provides a 300ms output signal upon touch. This principle allows the sensor to ignore the effects of material build-up on the sensing face and suppresses interference from water, ice, and particles that may adhere to the sensor surface. The sensor will trigger even when the operator is wearing gloves.
Static output: Remains on as long as the sensing face is being touched.
Bistable output: Changes its state upon being touched and maintains that state until it is touched again (a toggle function).

Adjusting Sensitivity According to the Environment

With the help of IO-Link, the brightness of the KT can be adjusted to adapt to room lighting, and the sensitivity can be adjusted for use in humid environments or when operating with gloves. The sensor’s start-up delay can prevent accidental switching operations. Even when used without IO-Link, the sensor still retains all of its settings. The sensor can also count switching cycles, which facilitates machine maintenance according to set schedules.

Lightly touch surfaces of different materials and adjust according to the application. Installation is very simple. Everything is easy!
