Overview
The Stromag 4.1 NM-499G is a rotary encoder assembly manufactured by Stromag AG (now GKN Stromag), a leading European supplier of industrial transmission and control components. This encoder is part of Stromag’s Series 51 geared cam limit switch product line, engineered for precision position sensing and limit switching in industrial machinery. The unit combines rotary encoding capability with contact switching, making it ideal for applications requiring both motion detection and discrete output signals.
Key Features
- 250VAC contact voltage rating with 10A current capacity
- Geared cam-driven limit switch mechanism for reliable position detection
- Rotary encoder output for continuous or incremental motion feedback
- Industrial-grade construction for heavy-duty manufacturing environments
- Compact modular design compatible with Series 51 frame specifications
