Bidirectional cross limit switches monitor mechanical travel in both positive and negative directions and provide dual- limit protection for either a linear or rotational system. Because contact terminals are arranged symmetrically about the center axes of rotation, motion across prescribed limits will always enable their reliable verfication, ideal for CNC machine tool slides, robotic arm articulations, and other systems with repetitive motion oscillating about fixed reference points. Most of these switches come with graranteed reset options and additional shielding against shock impacts changes ensuring high performance average parameters of operations in cyclic industry environments.
