PE2591 - PE-250-SEG14-MFRKG/US/ /E
Brand: IFM Electronic
Code: PE2591
- Two switching outputs, one of them programmable as IO-Link and one as analogue output
- Red/green display for clear identification of the acceptable range
- The process connection can be rotated for optimum alignment
- With long-term stability thanks to high overload protection
- Robust design for use in harsh industrial environments
