Non-contact linear absolute encoders – EXG

Non-contact open linear absolute encoders - EXG

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 10 mm wide reflective stainless steel tape that is highly resistant to solvents on an adhesive aluminum guide.

Measuring lengths in millimeters:
Available from 240 mm to 3,040 mm in 100 mm (*) increments.

Model description:
PG + TGA + L2A: non-contact open linear connector with a reader head that uses SSI protocol and a guided absolute tape with an adhesive aluminum guide.
PG + TGA + L2AM: non-contact open linear connector with a reader head that uses MITSUBISHI® CNC full dupllex protocol and a guided absolute tape with an adhesive aluminum guide.
PG + TGA + L2AM2: non-contact open linear connector with a reader head that uses MITSUBISHI® CNC half duplex protocol and a guided absolute tape with an adhesive aluminum guide.
PG + TGA + L2AP: non-contact open linear connector with a reader head that uses PANASONIC® (Matsushita) protocol and a guided absolute tape with an adhesive aluminum guide.
PG +TGA + L2AB: non-contact open linear connector with a reader head that uses BiSS® protocol and a guided absolute tape with an adhesive aluminum guide.
PG + TGA + L2AK: non-contact open linear connector with a reader head that uses YASkAWA® protocol and a guided absolute tape with an adhesive aluminum guide.
