Absolute optical encoders are position sensors that employ optical signals to identify an absolute angular position, as opposed to incremental optical or magnetic encoders. To create an absolute position, incremental encoders need to be started by a first turn.
An electro-mechanical device called an incremental encoder converts the angle of the shaft into digital or pulse signals using an optical disc. Each pulse, which is an increment equivalent to the specified resolution, is produced in a predetermined number of pulses each revolution.
The Global Incremental Optical Encoder market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Renishaw launched ATOM, a ground-breaking non-contact optical linear and rotary incremental encoder system that combines miniaturization with cutting-edge dirt immunity, signal stability, and dependability. Due to a design that forgoes the numerous trade-offs often found in miniaturized encoders, the new encoder achieves performance that is unparalleled.
The world’s smallest encoder, ATOM, uses filtering optics with Auto Gain Control (AGC) and Auto Offset Control. It is available in dimensions as small as 6.8 mm x 12.7 mm x 20.5 mm (AOC).
Excellent signal stability and remarkable dirt immunity are provided by this cutting-edge technology, which is included in Renishaw’s well-known Tonic incremental encoder line.
The flexible-printed circuit (FPC) and hi-flex cable versions of the ultra-compact ATOM incremental encoder are available with scale options of 20 m and 40 m. The side-exit FPC version decreases the size of the total package and enables PCB integration.
A variety of high-accuracy linear glass spars up to 130 mm in length, stainless steel tape up to 10 m, and rotating glass disc scales ranging in diameter from 17 mm to 108 mm are also available to customers. Designers can also link directly to analogue drives and controllers using the redhead’s sinusoidal signal output.
To provide the best quality, quick lead times, and competitive pricing, advanced, highly automated production techniques minimize process variability. The Tonic incremental encoder family from Renishaw uses this cutting-edge technology, which offers superior signal stability and dirt immunity.
