In This Section

  • ATEX

    ATEX is a directive used worldwide for equipment, including encoders, to be used around or in explosive atmospheres. ATEX certified equipment is NOT necessarily interchangeable with US-based UL Class/Division or Class/Zone rated equipment, nor IECEx rated equipment. ATEX is an alternative and different system. Review our full line of Avtron Explosion Protected, ATEX certified encoders, including M6, M6C and XR models.

  • Encoder

    A device which indicates position and speed via a set of digital outputs. Incremental encoders output quadrature (A Quad B) signals, and may add a marker pulse once per revolution.  Absolute encoders typically indicate position via a digital message, a set of parallel outputs, or analog values.

  • Explosion Protected

    Also known as Flameproof, explosion protected equipment has additional protection/safety enhancements for use in explosive atmospheres. Explosion Protected devices maybe placed directly into hazardous areas within their nameplate rating. No additional equipment is required if installation instructions are followed properly. By comparison, Intrinsically Safe devices may require the use of additional, external protection/current limiting devices outside of the hazardous area. Avtron offers hollow shaft M6C Explosion Protected encoders.

  • IECEx

    IECEx is a directive used worldwide for equipment, including encoders, to be used around or in explosive atmospheres. IECEx certified equipment is NOT necessarily interchangeable with US-based UL Class/Division rated equipment, or ATEX rated equipment. IECEx is an alternative and different system. Avtron offers a full famliy of Explosion Protected, IECEx certified XR encoders, and M6C is also IECEx certified.

  • Incremental Encoder

    An encoder that produces pulses in proportion to distance moved or rotated. Incremental encoders can also have a marker pulse Z, Z NOT (, ) once per revolution to provide a position reference. Avtron produces a full range of incremental rotary encoders.

  • UL Listed

    UL Listed Avtron encoders can be directly applied to any hazardous duty application which requires Class and Division, Class and Zone or AEX certification.  Note that UL Listing is a different system than ATEX or IECEx.  Ensure the model you select has the UL listing which meets the application requirements.
