1 Introduction

Safety Information for LR-TB Series

• This product is only intended to detect object(s). Do not use this product for the purpose to protect a human body or part of a human body.

• This product is not intended for use as an explosion-proof product. Do not use this product in a hazardous location and/or potentially explosive atmosphere.

• This product uses DC power. The product may explode or burn if an AC voltage is applied.

• Do not wire the cable along with power lines or high-tension lines, as the sensor may malfunction or be damaged due to noise.

• When using a commercially available switching regulator, ground the frame ground terminal and ground terminal.

• Do not use this product outdoors or in a location in which its light-receiving surface will come in direct contact with stray ambient light.

Safety Precautions on Laser Product

This product uses a semiconductor laser as its light source.

• Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

• Follow the instructions mentioned in this manual. Otherwise, injury to the human body (eyes and skin) may result.

• Laser emission from this product is not automatically stopped when it is disassembled. Do not disassemble this product.

• Precautions on Class 2 Laser Product

- Do not stare into the direct or specularly reflected beam.

- Do not direct the beam at people or into areas where people

might be present.

- Be careful of the path of the laser beam. If there is a possibility that the operator may be exposed to the specular or diffuse reflections, block the beam by installing a protective enclosure.

- Install this product so that the path of the laser beam is not as the

same height as that of human eye.

• Precautions on Class 1 Laser Product

- Do not stare into the direct or specularly reflected beam.

2 Installation and Wiring

Installation

• Tightening torque for the mounting holes: 0.63 N·m (M3 screw)

• If the detecting object has a mirrored surface, install the sensor in a position where specular reflection will not penetrate the optical receiver.

Wiring

With the LR-TB Series, you can select the functions of the I/O wires (black and white) from the combinations shown below during the initial settings. "3 Initial Settings" (page 3) Independently isolate any I/O wires that you will not use.

4-1. DATUM Mode (FGS)

 Operation

• In this mode, the change in position from a reference surface (which has a value of 0) is displayed.

• This mode is useful in detecting the passage of workpieces in front of a stationary background.
