Overview

Q2X Adjustable-Field Sensors with Background Suppression ignore objects beyond the set cutoff distance. Background suppression

mode can be used in most situations with varying object color and position or with varying background conditions.

Installation

Sensor Orientation

To ensure reliable detection, orient the sensor as shown in relation to the target to be detected.

Mount the Device

1. If a bracket is needed, mount the device onto the bracket.

2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten the

mounting screws at this time.

3. Check the device alignment.

4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.

Wiring

Cabled wiring diagrams are shown. Quick disconnect wiring diagrams are functionally identical.

CAUTION: Observe proper ESD precautions (grounding) when connecting quick disconnect models.
