Ifm Electronic TK7110 temperature switch 1xPt1000 PNP EL=50 mm 400 bar G 1/4 M12 content_copy

The electronic temperature switch TK7110 from Ifm Electronic is an industrial sensor for temperature monitoring in liquids and gases. It features a Pt1000 measuring resistor according to DIN EN 60751, Class A, and is designed for use in demanding environments. The switch operates with a PNP output and provides a switching signal that activates when the set temperature limits are reached. The insertion length is 50 mm, and the process connection is designed as G 1/4 external thread, enabling universal installation in pipelines. The electrical connection is made via an M12 connector, suitable for robust industrial applications.

Applications
The TK7110 is suitable for temperature monitoring in industrial processes, for example in manufacturing, the food industry, or power generation. It is designed for use in liquids and gases, with a pressure resistance up to 400 bar. The protection rating IP67 ensures dust and water resistance, allowing the sensor to be operated outdoors or in humid environments. Temperature measurement is performed in the range of −25 to 140 °C, enabling broad application in cool to hot processes.

Functions and Features in Detail
The temperature switch features two PNP switching outputs with fixed hysteresis, each operating as a NO contact (Normally Open). The switching points can be manually adjusted using two adjustment rings, allowing flexible adaptation to specific process requirements. The accuracy is ±3 K, ensuring reliable temperature detection. The response time is 1 second at T05 and 3 seconds at T09, enabling fast reaction to temperature changes.

Technology Explained Simply
The sensor uses a Pt1000 measuring resistor, whose resistance value increases linearly with temperature. This resistance is electronically evaluated to generate a digital switching signal. The PNP output function means that the output delivers a high level (High) when activated, which is common in industrial control technology. The supply voltage ranges from 9.6 to 32 V DC, enabling flexible integration into existing control systems. The M12 connector is a standardized, robust connection format protected against vibrations and mechanical stress.

Compatibility and Accessories
The TK7110 is equipped with a G 1/4 external thread, allowing direct installation in pipelines with corresponding internal thread. The M12 connector is compatible with standard cables and connectors for industrial sensors. No specific accessories are mentioned in the sources, so the delivery scope is limited to the sensor itself. No additional cables, adapters, or mounting accessories are included.

Installation and Mounting
Mounting is done by inserting the sensor into a pipeline or vessel with a matching internal thread G 1/4. The insertion length of 50 mm ensures sufficient thermal contact surface with the measured medium. The electrical connection is made via the M12 connector, which is connected to a suitable cable. The switching points are set on-site using the adjustment rings, eliminating the need for additional programming.

Operational Advantages
The TK7110 offers high reliability due to its robust construction and IP67 protection rating. Manual adjustment of switching points allows easy adaptation to different processes. The short response time ensures fast signal transmission, and the high pressure resistance of 400 bar makes the sensor suitable for high-pressure applications. The operating voltage of 9.6 to 32 V DC enables flexible integration into existing control systems.
