About this role
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 Contact: Sarah Disch
