TAR-200 Encoder
Description
The TA series encoders are optical reflection incremental type encoders that have interpolator, combinate with linear/rotary scale, get small size, high resolution and low cost. Adopted a sensor of the diffraction image projection method for a optical head, that includes a LED light source and photo detector in a package. It outputs differential outputs with pure sine wave signal of 80μm in A,B phase. In addition, it outputs index signal by Z(index) phase signal from the same sensor. This TA series modules are packaged small and thin(1.5mm) optical head which is composed a rigid flexible print board (RFPCB) with embedded the sensor on it. With its excellent pure sine wave outputs from the optical head of the module, achieved high interpolation ratio and up to 200 resolution for each of A,B phase. Hence up to 0.1μm resolution for linear and 0.000125° resolution for rotary is possible by combination with user's circuit. Linear encoder products that have limit sensors on both of the head edges are available as well.

Features
Enabling small thin type optical sensor head (10 × 15 × 1.5mm)
Selectable interpolation resolution up to 200 times
Available analog sine wave outputs from a optical reflection type sensor
Easy to install because of its wide gap tolerance between a optical head and a scale, besides an auto calibration function of the sensor head
Developed new products of encoder head with limit sensors
Combined a pattern of scale for Z(index) phase with incremental patterns for A,B phase, hence achieved a narrow and thin scale
Increased noise resistance by adopting a 6 layers shielded RFPCB(t=0.1mm)
Enabling low cost by adopting nickel steel for a scale ・Available glass scales for high precision use

Frequently Asked Questions
The features of the TA-200 Encoder include enabling a small thin type optical sensor head (10 × 15 × 1.5mm), available analog sine wave outputs from an optical reflection type sensor, easy installation due to its wide gap tolerance between an optical head and a scale, and an auto calibration function of the sensor head.
The TA-200 Encoder uses differential output signals of A+, A-, B+, B-, Z+, Z- to enable high noise immunity. It outputs A,B signals from the interpolator, Z phase(index) signals from the encoder head, and Z phase(index) signal from the interpolator.
The TA-200 Encoder has a selectable interpolation resolution of up to 200 times, which enables up to 0.1μm resolution for linear and 0.000125° resolution for rotary by combination with user's circuit.
The TA-200 Encoder is an optical reflection incremental type encoder that has an interpolator, combined with linear/rotary scale, and is small in size, high in resolution, and low in cost.
The TA-200 Encoder enables low cost by adopting nickel steel for a scale and is available with glass scales for high precision use. It also has increased noise resistance by adopting a 6 layers shielded RFPCB(t=0.1mm).
