SMG26 Incremental Optical Encoder

The Precise Scale of the Microscopic World  
Ultra-Compact Incremental Optical Encoder System

4nm Resolution | 4.3mm Ultra-Compact Thickness | 95%RH Humidity Resistance

The SMG26 Incremental Optical Encoder, independently developed by ZEPTOOLS, is a perfect interpretation of the philosophy "Tools for Small World." We adopt an ultra-compact package design, compressing the readhead to an extremely compact size, allowing it to easily fit into high-end equipment where internal space is at a premium, such as laser scanners, coordinate measuring machines, and semiconductor manufacturing equipment.

The SMG26 is available in two forms: aluminum alloy package and PCBA, and offers excellent environmental adaptability, supporting stable operation under high-humidity conditions, freeing your precision designs from the constraints of space and installation tolerances. Whether for precision instrument R&D or harsh industrial sites, it provides stable and reliable displacement feedback.
