This report studies the optical scales, also called linear encoders. Linear encoders measure the position of linear axes without intervening mechanical elements. This eliminates a series of potential error sources such as backlash, pitch error, or heating of the recirculating ball screw. Wherever rigorous position accuracy and high machining speeds are needed, linear encoders are essential.
Types of Linear Encoders include:
Sealed Linear Encoders: Sealed linear encoders feature optimal protection from dust, chips, and splash water. They are especially ideal for use in manually operated machine tools and also in numerically controlled machine tools.
Exposed Linear Encoders: Exposed linear encoders have zero mechanical contact between the scanning head and the scale or scale tape. Applications include production and measuring equipment in the semiconductor industry, as well as pick-and-place machines and direct drive systems.
The global Optical Scales market was valued at US$ 440 million in 2023 and is anticipated to reach US$ 640 million by 2030, witnessing a CAGR of 5.1% during the forecast period 2024-2030.
Currently the key manufacturers of optical scales include HEIDENHAIN, Fagor Automation, Renishaw, Mitutoyo, TR-Electronic GmbH, TR-Electronic GmbH, and Givi Misure. Among them, HEIDENHAIN is the world's largest linear encoders manufacturer, accounting for more than 50% of the global market share.
CNC machine tools are the largest application market for optical scales. According to our research, the global CNC machine tool market size was US$ 60 billion in 2023 and is expected to reach US$90 billion in 2030. The global key manufacturers of CNC machine tools include Yamazaki Mazak, Trumpf, Okuma Corporation, Makino, JTEKT Corporation, DMG Mori Seiki, DN Solutions, Grob-Werke, Haas Automation, Hermle, etc. In 2023, the global top five players had a share approximately 20 % in terms of revenue.
