Part Identity and Function
The Siemens 3RK1901-2DA00-0AL3 is a K45 mounting plate designed for Leuze Lumiflex safety light curtains. This is a mechanical accessory, not an electronic module — its job is to provide a fixed mounting interface between the light curtain housing and the machine frame or guarding structure.
Deployment Context
The K45 mounting plate is a mechanical bracket — it does not carry electrical ratings, IP protection, or safety integrity levels itself. It is used in safety guarding applications where a Leuze Lumiflex light curtain must be mounted to a machine frame, typically in a panel or enclosure cutout. The plate ensures the sensor column is rigidly aligned and vibration-resistant.
