Optical Encoder Disks For Precision Positioning

PEI is offering a full line of photoetched optical encoder discs for industrial, military and aerospace applications which require precision positioning. These stiff discs with radial slits are available in a wide variety of line counts, tracks, and materials, including stainless steel, nickel, and beryllium copper; they can also be blackened to make them anti-reflective in light-sensitive applications.

PEl is able to provide encoder discs with extremely small slot resolution (line widths as small as 0.004 in. [0.10 mm], in a wide range of thicknesses depending on the encoder specifications. Tolerances can typically be held within 10% of the material thickness.

Because PEl makes its own phototools in-house and uses a chemical photo etching process, we can manufacture highly-accurate optical encoders with exact repeatability from one slot to the next. Our turn-around times are outstanding: typical delivery is three weeks from receipt of order and customer prints. All parts are burr-free and stress-free to ensure longer life and greater reading accuracy. Anvil mounting is available as well.

PEls manufacturing process has achieved ISO-9002 certification, and also complies with MIL-I45208 standards. We can supply prototypes that meet customer specifications, or our Custom Fngin~ering De:partf11ent Gan help customers design products that meet their specific encoder requirements.
