The enclosure can include a housing having an end wall, sidewalls, a top wall, and a bottom wall. A door is hinged to the top wall. The enclosure can have a linkage assembly including a door lever having an elongate first end portion connected to the door, a laterally extending second end portion, and an elbow positioned therebetween. A pivot arm having a proximal end is connected to an interior surface of the housing and a distal end of the pivot arm is connected to the elbow. An actuator can be connected between the housing and the laterally extending second end portion. The linear actuator can be positioned with respect to the door lever and pivot arm to move the door to an open position when extended and a closed position when retracted. ## Claims ### Claim 1 A harsh environment enclosure, comprising: a housing having an end wall, a pair of opposed sidewalls, a top wall, and a bottom wall; a door hinged to an inner surface of one of the top wall and the bottom wall; a linkage assembly, including: a door lever having an elongate first end portion connected to the door, a laterally extending second end portion, and an elbow portion positioned therebetween; a pivot arm having a proximal end portion rotatably connected to an interior surface of the housing and a distal end portion rotatably connected to the elbow portion; and a linear actuator having a first actuator end portion connected to an interior surface of the housing and a second actuator end portion connected to the laterally extending second end portion; wherein the linear actuator is positioned with respect to the door lever and pivot arm to move the door to an open position when extended and a closed position when retracted. ### Claim 2 (depends on 1) The enclosure of claim 1, wherein the door is hinged to the top wall and the laterally extending second end portion extends toward the top wall. ### Claim 3 (depends on 1) The enclosure of claim 1, wherein the door lever has an L-shaped configuration. ### Claim 4 (depends on 1) The enclosure of claim 1, wherein the pivot arm is connected to one of the pair of opposed sidewalls. ### Claim 5 (depends on 1) The enclosure of claim 1, wherein the pivot arm is limited to a range of rotation of approximately 140 degrees. ### Claim 6 (depends on 1) The enclosure of claim 1, wherein the pivot arm and door lever are positioned in an over-center configuration when the door is in the closed position. ### Claim 7 (depends on 1) The enclosure of claim 1, wherein first actuator end portion is connected to the end wall. ### Claim 8 A harsh environment sensor system, comprising: a housing having an end wall, a pair of opposed sidewalls, a top wall, a bottom wall, and a sensor compartment having a sensor opening; a door hinged to an inner surface of the top wall proximate the sensor opening; a linkage assembly, including: a door lever having an elongate first end portion connected to the door, a laterally extending second end portion, and an elbow portion positioned therebetween, wherein the second end portion extends toward the top wall; a pivot arm having a proximal end portion rotatably connected to an interior surface of the housing and a distal end portion rotatably connected to the elbow portion; and a linear actuator having a first actuator end portion connected to an interior surface of the end wall and a second actuator end portion connected to the laterally extending second end portion; wherein the linear actuator is positioned with respect to the door lever and pivot arm to move the door to an open position when extended and a closed position when retracted, and wherein the pivot arm and door lever are positioned in an over-center configuration when the door is in the closed and open positions; and a sensor module disposed within the sensor compartment. ### Claim 9 (depends on 8) The sensor system of claim 8, wherein the pivot arm is connected to one of the pair of opposed sidewalls. ### Claim 10 (depends on 8) The sensor system of claim 8, wherein the pivot arm is limited to a range of rotation of approximately 140 degrees. ### Claim 11 (depends on 8) The sensor system of claim 8, wherein the door lever has an L-shaped configuration. ### Claim 12 (depends on 8) The sensor system of claim 8, further comprising a second linkage assembly wherein each linkage assembly is positioned adjacent a corresponding one of the pair of sidewalls.
