  • Intrinsically-safe, explosion-proof encoder
    Patent number: 10641624
    Abstract: An encoder includes a housing including a first set of one or more sidewalls defining a first zone, a second set of one or more sidewalls defining a second zone, and a protection partition having a first surface oriented toward the first zone and a second surface oriented toward the second zone. The protection partition has a sensor opening defined therethrough between the first zone and the second zone. A board stack assembly having a plurality of elevations is positioned such that an interface device and a first portion of a protective wire feedthrough are in the first zone and a second portion of the protective wire feedthrough extends through the sensor opening between the first zone and the second zone. The protective wire feedthrough is coupleable to a sensor device in the second zone. A cover engages the first set of one or more sidewalls to seal the first zone from an ambient environment.
