Laser Displacement Sensors

Laser displacement sensors focus a semiconductor laser beam on a target and use the reflectance of the beam off the target to determine the presence of a target and distance to it.

Applications

•  Measuring distance.
• Detection of presence or absence of a feature.
• Confirmation of part or object passage.
• Positioning of work piece.

Features

• Non-contact.
• Works in harsh environments.
• Some devices can achieve measurement precision down to .004 mils (0.1µm).
