Non-contact linear incremental encoders – EXA

Non-contact open linear incremental encoders - EXA

Non-contact open linear encoder for high accuracy, high speed applications.

It consists of a compact reader head with all the electronics and optics integrated into a single body that may be mounted from the side or from the top.
It has an LED to help mounting it and includes a 1 or 3 meter cable with a connector, a 6 mm wide adhesive reflective stainless steel tape that is highly resistant to solvents and reference signal synchronized on line.

Measuring lengths in millimeters:
Available from 70 mm to 16,020 mm in 50 mm increments.

Model description:
TA + L2R: non-contact open linear connector with an incremental reader head, incremental I0 (every 50 mm) and an adhesive incremental tape.
TA + L2S: non-contact open linear connector with an incremental reader head, I0 that may be selected with a magnet and an adhesive incremental tape.

Characteristics:
  TA + L2RD TA + L2RX TA + L2RY TA + L2RW TA + L2RW1 TA + L2RP
Measurement Incremental: By means of a 20 μm-pitch graduated steel tape
Steel thermal expansion coefficient αtherm: ≈ 11 ppm/K.
