Omron EE-SX670-WR 1M E3Z Series Photoelectric Sensors Built-in Amplifier

The Omron EE-SX670-WR 1M is a compact photoelectric sensor with a built-in amplifier, belonging to Omron's E3Z series (though sometimes categorized under the EE-SX series for specific models). It is designed for precise object detection in automation and industrial applications.

Key Features of the EE-SX670-WR 1M:

✔ Detection Type: Through-beam (opposed mode) – Requires a separate emitter (EE-SX670A) and receiver (EE-SX670B).

✔ Sensing Distance: 5 mm (0.5 cm) gap – Extremely close-range detection for small objects.

✔ Light Source: Red LED (650 nm wavelength) – Visible for easy alignment.

✔ Output Type:

NPN (sinking) transistor output – Compatible with PLCs and control systems.

1-meter (1M) cable pre-attached for easy wiring.

✔ Response Time: 0.5 ms max – Ultra-fast for high-speed applications.

✔ Enclosure Rating: IP50 (basic dust protection, not waterproof).

✔ Compact Size: 20 × 10 × 6.5 mm (W×H×D) – Fits in tight spaces.

Typical Applications:

PCB assembly & electronics manufacturing (detecting tiny components).

Printing machinery (paper jam detection).

Precision automation (small part positioning).

Medical devices & lab equipment (sensitive object sensing).
