Connectivity for

Industrial Sensors

HARTING provides I/O connectors for the transmission of power, signal, and data to and from sensors. Smart connector design enables easy installation and space savings.

HARTING connectors are used for powering and transferring data to and from the sensors.  Our connector portfolio supports design needs for miniaturization, robustness, and higher data transfer rates.

Design Considerations / Trends for Industrial Sensors

The below table refers to frequent design considerations / trends important for engineers designing industrial sensors.  The recommended products you found above are included and rated for how well they fit these trends.  

High Data Transfer Rate
Sensors are becoming smaller / more compact in order to add more functionality or save space. Smaller components help reduce the size .
Sensors need to be able to transfer high amounts of data as quickly as possible. Connectors must be rated to handle the high transfer rates.
All components for sensors operating in industrial environments should have an IP rating suitable for that environment to ensure reliability.
M8 D-code (30% smaller than M12 D-Code) and Y-Code hybrid versions available in addition to standard options
IP65/67 Ratings
M8 D-code (30% smaller than M12 D-Code) and Y-Code hybrid versions available in addition to standard options
Up to 10 Gbit/s
IP65/67 Ratings
Reduces space needed around the connector
Up to 10 Gbit/s
Save board space with magnetics integrated into the connector
Up to 10 Gbit/s
IP65/67 with M12 housings

Frequently Asked Questions

What is an industrial sensor?

A industrial sensor is a device used on a piece of industrial equipment for detecting physical phenomenon like light, vibration, temperature, humidity, etc... 

In the broadest definition detects events or changes in its environment and sends the information to other electronics, like a PLC, which will make decisions based on input coming from the sensor.
