XN 30mm E-Stop Switches IDEC XN 30mm E-Stop Switches utilize a safe break action technology to ensure the highest level of safety. This technology ensures that Normally Closed (NC) contacts will open if the contact block is damaged or separated from the operator due to excessive force. Direct opening action ensures that even if the contacts are welded, the force applied to the button will directly open the contact. These e-stop switches feature a safety interlock mechanism that keeps contacts open when the operator is locked. The XN series switches offer padlock-type e-stops to prevent unauthorized or accidental resetting of latched emergency stop switches by allowing the use of up to 20 personal padlocks. Typical applications include robotics, automotive, pharmaceuticals, manufacturing, and food and beverage processing.
