Tiny non-contact encoders provide high-resolution rotary or linear position feedback

A series of three miniature magnetic encoders suit embedded OEM motion control applications in medical applications, optics positioning, robot control, 3D printers, gimbals and hand held devices. The miniature encoders come in four different shapes and provide linear resolution up to 0.244 µm, or 753,664 cpr for rotary applications.

The encoders consist of a miniature sensor and a magnetic scale or a ring. The sensors are available in a potted housing or as PCB board-level sensors. Position information can be output in incremental quadrature TTL or RS422, as well as parallel in SSI and BiSS-C formats, with the option of a unique or periodic reference mark. The industrial designs bring long-life, wear-free, low-inertia advantages to difficult applications and harsh environments.

RoLin—for integration into small motion systems A magnetic position encoder for either linear or rotary position feedback. It is available as a “PCB-ready” readhead for integration into small motion system designs. It is also available as a stand-alone packaged readhead with flex cable connection. It can provide interpolation rates up to 13-bit, as well as fault monitoring, with speeds up to 40 m/sec, depending on resolution. RLC—two designs for direct PCB installation or cable soldering This board-level magnetic encoder is for integration into high volume OEM systems. High speed, high reliability and high resolution coupled with large installation tolerances allow this encoder to be installed quickly and cost effectively. Magnetic scale technology ensures that position feedback is maintained even if the scale is severely contaminated. RLB—with FPC flat cable connector for higher volume OEMs Similar to RLC, this encoder’s FPC connection lets you use a cable and connector, rather than solder assembly.
