Overview
The 6ES7194-7MA00-0AA0 is a Siemens ET200clean accessory — a stainless steel fixing screw M5x50 mm with a hygienic seal, supplied in a pack of 10 units. It is used to mount ET200clean I/O modules in washdown environments where standard fasteners would trap bacteria or corrode.
Integration & mounting
Each pack of 10 screws weighs 132.0 g. The M5 thread and 50 mm length fit ET200clean mounting holes.
Applications
This screw is part of the SIMATIC ET200clean accessory range, designed for I/O systems installed in hygienic zones — typically food processing, beverage bottling, dairy, and pharmaceutical packaging lines where equipment must withstand high-pressure washdown and chemical sanitizers. The stainless steel and seal ensure the fastener does not become a contamination point.
