The IQS263B-0-DNR is an Industrial Sensor Connectivity Solution for capacitive touch sensing applications. It is a controller-cum-sensing-element that provides a capacitive sensing interface for a wide range of industrial applications from simple human-machine-interface (HMI) input products to motion and positioning feedback. Its design and application are optimized for industrial environments, even in harsh or wet conditions and with impedance across contact surfaces.

The technology works on the principle of capacitive sensing. A conductive contact surface is placed near the sensor pad and forms a capacitive coupling through dielectric medium. The charge and discharge of this capacitance determines the amount of current flowing in the sensing element and its sensing output is then converted into a digital signal through an on-chip comparator. This combination of components and measurement principles provide very fast detection and response times and a strong immunity to EMI, making the device ideal for demanding industrial use cases.

The IQS263B-0-DNR has been designed to work in a variety of applications without needing additional external components. This includes applications like industrial switches, outlet covers, operating panels, and other industrial controls and HMI input products. It has excellent wet touch performance, making it suitable for uses in harsh industrial environments or wet locations, as well as for medical applications.

The device is easily integrated into a system with a simple ‘wire or clip’ installation. Its wide range of programmable features allows it to be tailored for use in a variety of applications. The device can be programmed to work with a wide range of sensing surfaces and material types that are compatible with the capacitive sensing principles. It also features variable sensitivity settings to cater for different environment and product settings. Additionally, the device has on-chip temperature compensation and power-saving modes for extended life and cost optimisation.

The IQS263B-0-DNR is a reliable and cost-effective solution for capacitive touch sensing applications in industrial environments. Its fast detection speeds, strong immunity to EMI, and flexible design allows it to be used in a variety of applications, while its ‘wire or clip’ installation and temperature compensation enable optimised performance and cost-reduced solutions. The development of the device has been an immense benefit to the industrial field, providing the perfect interface between users, controls, and devices.
