Omron E3F-DS30C4 E3Z Series Photoelectric Sensors Built-in Amplifier

The Omron E3F-DS30C4 is a compact, self-contained photoelectric sensor from the E3Z series with a built-in amplifier, designed for reliable object detection in industrial automation applications.

Key Features of the E3F-DS30C4:

✔ Detection Type: Diffuse-reflective (detects objects without a separate reflector).

✔ Sensing Distance: 30 cm (300 mm) max. (adjustable sensitivity).

✔ Built-in Amplifier: No external controller needed—direct NPN/PNP output.

✔ Output Type:

NPN (E3F-DS30C4) – Sinks current (common in PLC inputs).

(PNP version available as E3F-DS30P4).

✔ Light Source: Red LED (650 nm, visible for easy alignment).

✔ Response Time: 1 ms max (fast for high-speed applications).

✔ Enclosure Rating: IP67 (dustproof & waterproof for harsh environments).

✔ Adjustable Sensitivity: Potentiometer for fine-tuning detection.

✔ Indicator LEDs:

Power (green) – Power status.

Stability (orange) – Detection stability.

Output (red) – Active when object detected.

Typical Applications:

Conveyor belt object detection (packaging, sorting).

Machine automation (part presence/absence verification).

Material handling (box, bottle, or workpiece counting).

Robotic cell safety & positioning.

Wiring & Connections:

3-Wire Connection:

Brown (+V, 12-24V DC)

Blue (0V/GND)

Black (Output signal)

Load Compatibility: Connects directly to PLCs (Sinking input), relays, or counters.
