A door latching mechanism for a wafer container, comprising: a cammed plate including a first face, a second face opposite said first face, and an outer perimeter, said cammed plate being rotatable about a central axis that is substantially perpendicular to said first face and said second face, said cammed plate defining an arcuate camming slot that passes through said first face and said second face, said arcuate camming slot being bound by an inner perimeter having a first cam surface and a second cam surface, said second cam surface being opposite said first cam surface; a cam follower disposed within said camming slot, said cam follower being selectively engageable with said first cam surface and said second cam surface; and a latch arm translatable along an actuation axis and including a proximal end having a first extension and a second extension, each extending in a direction parallel to said actuation axis, said first extension and said second extension extending over said outer perimeter of said cammed plate so that said first extension is adjacent said first face of said cammed plate and said second extension is adjacent said second face of said cammed plate, said cam follower being coupled to said first extension and said second extension, wherein, when said cammed plate is rotated about said central axis in a first rotational direction, said first cam surface engages said cam follower to exert a force on said first extension and said second extension of said latch arm in a first translational direction along said actuation axis, and wherein, when said cammed plate is rotated about said central axis in a second rotational direction that is opposite said first rotational direction, said second cam surface engages said cam follower to exert a force on said first extension and said second extension of said latch arm in a second translational direction along said actuation axis, said second translational direction being opposite said first translational direction. a cammed plate including a first face, a second face opposite said first face, and an outer perimeter, said cammed plate being rotatable about a central axis that is substantially perpendicular to said first face and said second face, said cammed plate defining an arcuate camming slot that passes through said first face and said second face, said arcuate camming slot being bound by an inner perimeter having a first cam surface and a second cam surface, said second cam surface being opposite said first cam surface; a cam follower disposed within said camming slot, said cam follower being selectively engageable with said first cam surface and said second cam surface; and a latch arm translatable along an actuation axis and including a proximal end having a first extension and a second extension, each extending in a direction parallel to said actuation axis, said first extension and said second extension extending over said outer perimeter of said cammed plate so that said first extension is adjacent said first face of said cammed plate and said second extension is adjacent said second face of said cammed plate, said cam follower being coupled to said first extension and said second extension, wherein, when said cammed plate is rotated about said central axis in a first rotational direction, said first cam surface engages said cam follower to exert a force on said first extension and said second extension of said latch arm in a first translational direction along said actuation axis, and wherein, when said cammed plate is rotated about said central axis in a second rotational direction that is opposite said first rotational direction, said second cam surface engages said cam follower to exert a force on said first extension and said second extension of said latch arm in a second translational direction along said actuation axis, said second translational direction being opposite said first translational direction.
