Choose from two types: front detection and side detection.
This model offers a space-saving design similar to conventional models. Two models, front detection and side detection, are available, allowing you to choose the model based on the installation location.

Rugged & Ultra-Thin Structure
This industry-first ultra-thin optical encoder, at 14mm thick, is ideal for applications requiring tight spaces, close-fitting installations, or concealed locations. It can be used in AOI (Automated Optical Inspection) equipment for protection or as a start signal. While conventional rugged encoders typically have a thicker structure, this product achieves a super-thin design.

Thinner, wider range of use
The thinner light curtain sensor increases the device’s working width, significantly improving workability.

Custom shapes, lengths, and beam counts based on customer needs.
For models not listed in the product specifications, customers can contact sales staff to customize the shape, length, and beam count to meet their specific needs.
