PHOTOFABRICATION ENGINEERING, INC. (PEI), Milford, MA (January 31, 2011) 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.
PEI 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 thickinesses depending on the encoder specifications. Tolerances can typically be held within 10% of the material thickness.
Because PEI makes its own phototools in-house and uses a chemical photoetching 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.
PEI's manufacturing process has achieved ISO 9001:2008 certification and also complies with MIL-I-45208 standards. We can supply prototypes that meet customer specifications, or our Custom Engineering Department can help customers design products that meet their specific encoder requirements.
Applications for PEI's optical encoder discs include motion control, optical readers and precision positioning devices.
