Overview
The Baumer IFFM 20P17A3/S35L is a compact rectangular inductive proximity sensor engineered for high-reliability object detection in industrial automation. This flush-mount sensor delivers an 8 mm nominal sensing distance and features a PNP make function (normally open) output, making it ideal for proximity-based automation, position sensing, and machine control applications.
Key Features
- 8 mm Nominal Sensing Distance — Fast, consistent object detection for metallic targets
- PNP NO Output Circuit — Direct logic-level compatibility with most industrial controllers and PLCs
- M8 Connector — Standardized quick-disconnect interface for rapid integration and serviceability
- 500 Hz Switching Frequency — Supports dynamic, high-speed sensing applications
- Short Circuit & Reverse Polarity Protection — Built-in protection extends sensor lifespan and reduces downtime
- IP67 Rating — Sealed against dust and water ingress for harsh operating environments
- Adjustable Hysteresis — 3–20% of sensing range for fine-tuned response in critical applications
