Job Description
Mandatory Internship/Thesis: Power over Ethernet Integration for 3D Safety Sensors

Winter semester 2026/2027 – fixed term of 5–6 months

 

Our 3D safety sensors are among the core technologies in Factory Automation – and integrating Power over Ethernet opens up new possibilities for their power supply. In this internship/thesis, you actively contribute to the development of a forward-looking supply concept, working closely with our development team.

 

YOUR TASKS:

  • You research and analyze relevant PoE standards (e.g., IEEE 802.3af/at/bt)

  • You compare various PoE architectures and supply concepts for industrial sensors and evaluate them against the current power supply concept of a high-resolution 3D safety sensor

  • You develop a suitable hardware concept for PoE integration and implement it in a circuit design and an evaluation PCB

  • You examine compliance with relevant PoE requirements and standards

  • You analyze and evaluate a switching concept between PoE and direct supply (power OR-ing)

  • You investigate the effects on digital safety outputs (OSSDs) and their supply concept

  • You conduct measurements regarding efficiency, power loss, switching behavior, robustness, and EMC influences

  • You document and present your results

 

YOUR PROFILE:

  • You are enrolled in a degree program in Electrical Engineering, Mechatronics, Embedded Systems, or a comparable field

  • You bring foundational knowledge in analog and digital circuit design

  • You have an interest in power supplies, power electronics, and industrial communication

  • Initial experience with PCB design tools is an advantage

  • Familiarity with lab and measurement equipment is desirable

  • An independent, structured, and analytical way of working sets you apart
