The L15 provides the industrial marketplace with a rugged high resolution encoder in a compact size 15 servo package. Engineered with robust interpolative electronics, the L15 offers up to 40,640 cycles per turn. Ideal for space or weight limited applications, these compact encoders discount size without compromising performance.
The L15 encoder features a 1/4-inch diameter stainless steel shaft and can accommodate up to 5 pounds radial or axial load. The L15 encoder package has field-proven ASIC electronics, sealed dual bearings and BEI’s accurate code disk in an all metal housing to ensure ruggedness and reliability.
Applications: Factory automation; motor feedback; conveyors; automated warehousing; general industrial system monitoring and feedback.
