Our phased-array ASIC technology allows for the widest air gap in the industry, with an approximate 0.030" air gap vs. other masked technology processes requiring air gaps of 0.003-0.005". This enables most Duncan encoders to be very tolerant, enabling them to be installed easily without tight tolerance constraints. Resolution ranges are available up to 2540 ppr. Commutation is also available.

BEI Duncan Electronics offers its traditional responsiveness and packaging strengths across its encoder product line and capabilities. Here, the advantages of combining encoder/potentiometer or other functions into innovative packaging designs that will fit exactly where needed, all at low cost, with reliable long-service life, can give you the edge in design and lower total cost of ownership.

Ideally suited for integration into motors or other tight packaging constraints, the BEI Duncan MOD 700 Series introduces a highly miniaturized rotary incremental encoder that accommodates a broad range of standard code disk resolutions and diameters.

The new, MX15 and MX21 Series INSTA-MOUNT™ Modular Optical Encoders can be installed faster than any other standard encoder on the market, with the flexibility of assured "jitter-free" output signals without demanding tight controls on shaft endplay, runout or perpendicularity.

The KX21 Series offers a new, modular style, providing instant, low-skill installation flexibility in a true, static set screw mountable design.

Duncan's EX20 and EX11 Series Enclosed Shaft Encoders offer compact design in one of the industry's highest resolution encoders at the lowest cost, available in servo and flange-mount configurations.

Opto-ASIC encoders are ideal for customization to meet individual customer requirements for a wide range of industrial and consumer applications. With the selection available in Duncan's Incremental Encoder family, you can be assured of next-generation position sensing capabilities.
