The compact Series 61 emergency stop button from EAO is particularly suitable for mobile operating units, but can also be installed directly on the machine and in easily accessible locations. The button protects people and machines from injury and damage and, according to the supplier, complies with the latest standard requirements. Its robust monoblock design offers a tamper-proof release mechanism for interrupting the electrical contacts as well as a green ring marker to indicate whether the button has been actuated. One feature is the mechanically decoupled triggering of the switching elements, while optional bright illumination using a centered LED makes the device clearly visible even in low light conditions. Each button can be combined with a maximum of three individual NC or NO contacts, a push-button cover with a diameter of 27 or 40 mm and optionally with a 24 V (DC) LED with an installation depth of 21.2 mm.
