Optical Encoder iCs

Designed for absolute encoders and features a configuration of multiple differential photodiodes (PD) arranged in a specific phase array. It delivers high precision 3-channel sinusoidal output signals, both positive and negative. With support for high-resolution interpolation, it can achieve up to 24-bit resolution. The unique PD design enables stronger outputs even in low light conditions.

Also designed for absolute encoders, this chip arranges multiple differential photodiodes (PD) into a specific phase array to produce high precision 3-channel output (N channel, S channel, M channel) with both positive and negative sinusoidal signals. This chip supports high-resolution interpolation, achieving up to 24-bit precision, and is equipped with PD technology that enhances output amplitude in low lighting.

This is a compact, lens-free reflective encoder chip featuring an integrated infrared LED. Its small size is complemented by a high-density phase array PD that ensures exceptional signal quality, with a grating pitch of 80μm. Both the code disk diameter and grating scale length can be customized according to customer specifications.

This optical reflective absolute encoder chip integrates a blue LED chip and two PD arrays, achieving excellent signal fidelity even with loose alignment tolerances. It offers effective resolution of up to 16 bits, and its three-channel redundancy design significantly lowers bit error rates. This chip is typically used in high-resolution rotary and linear position applications.
