E3FDS30C4 Optoelectronic Photoelectric Sensor Switch Key benefits Provides reliable non-contact detection using diffuse reflection, reducing wear and maintenance compared to mechanical switches. Simple integration into DC control systems thanks to NPN output and normally open (NO) switching behavior. Suitable for automated presence, position, and counting tasks where consistent optical detection is required. How it solves problems Replaces mechanical sensors to eliminate contact-related failures and downtime. Detects objects without needing a separate reflector, simplifying installation and alignment. NPN DC output offers straightforward wiring into common industrial control inputs and PLCs that accept sinking signals. Standout features Model: E3FDS30C4 — an optoelectronic photoelectric diffuse-reflection proximity switch. Output type: NPN DC, normally open (NO). Operation: Diffuse reflection sensing for direct object detection from the sensor face. Reliability: Designed for consistent detection performance across routine industrial tasks. Package: Supplied as 1 piece. Important attributes (concise) Function: Photoelectric proximity detection using diffuse reflection. Compatibility: NPN DC sinking output; suitable for systems expecting NO contacts that close when a target is detected. Performance: Provides repeatable detection for presence/absence and position sensing; reduces mechanical wear by operating contactlessly. Installation: Single unit included; no reflector required. Typical applications Conveyor part detection: Detect passing parts or packages on a conveyor for counting, sorting, or triggering downstream processes. Assembly and pick-and-place stations: Verify presence or position of components at feeding or assembly points. Packaging and inspection: Confirm object presence before sealing or trigger inspection cameras when an item enters the field of view. What to consider Verify your controller or input module accepts NPN (sinking) DC signals and that normally open behavior matches your control logic. Confirm environmental and mounting requirements for your application (enclosure, temperature, and vibration) before installation. Includes 1 piece E3FDS30C4 optoelectronic photoelectric diffuse-reflection proximity sensor (NPN DC, normally open).
