Precision in Every Degree: Turck’s CMTH Sensor with IO-Link

In modern industrial environments, temperature and humidity are not just numbers on a display - they are decisive factors for uptime, product quality and equipment safety. From control cabinets and storage facilities to demanding production lines, keeping environmental conditions within safe limits has become a strategic priority. Turck’s new CMTH sensor with IO-Link combines temperature and humidity monitoring in one compact device, offering engineers a smarter way to safeguard their operations.

Two Measurements, One Device

Instead of installing separate sensors, CMTH provides both values simultaneously in a single unit. This saves space, reduces installation costs, and eliminates the need for complex calibration of multiple devices. What’s more, its IO-Link connectivity integrates seamlessly into modern IIoT infrastructures, enabling real-time data transfer to SCADA, MES or cloud-based systems. For maintenance teams, this means a clear step toward predictive monitoring, where risks are detected before failures occur.

Built for the Factory Floor

Whether protecting electronics in control cabinets from harmful condensation, maintaining optimal storage conditions for sensitive goods, or stabilising production parameters on the shop floor - CMTH is a versatile solution. Its compact housing and robust design allow installation even in confined or demanding industrial environments, ensuring reliability where it matters most.

IO-Link: Gateway to Industry 4.0

The integration of IO-Link is more than just a technical feature - it is a direct link to the digitalised future of manufacturing. IO-Link enables not only continuous data collection but also flexible sensor parameterisation, helping manufacturers adapt CMTH to their specific processes. Combined with cloud integration and analytics, it delivers the transparency needed for smart, data-driven decision-making.

A Reliable Partner in Supply

Advanced technology alone does not guarantee reliability. What truly counts is long-term availability of parts and a trusted partner who can deliver them on time. Automation Trader has built its reputation by providing industries with dependable access to automation components, including Turck solutions. Partnering with them ensures that investing in CMTH is backed by strong logistics and service support.


Turck’s CMTH is not just another environmental sensor - it is a compact, intelligent solution designed for the realities of Industry 4.0. By combining robust monitoring with the flexibility of IO-Link, it sets a new benchmark for environmental control. For manufacturers striving to protect their assets and optimise processes, CMTH offers both precision and peace of mind.
