In accordance with the Machinery Directive, plant and machinery must be fitted with emergency stop equipment so that a hazard can be averted or reduced in an emergency. In a dangerous situation, emergency stop control devices are operated manually, triggering a signal to halt a potentially hazardous movement. By generating the emergency stop command the emergency stop control device is latched in. This must be maintained until the control device is released manually.
For worldwide use, the emergency stop pushbuttons PITestop meet all the relevant international standards and regulations, such as EN/IEC 60947-5-1, EN/IEC 60947-5-5 and EN ISO 13850. Suitable for applications up to SIL CL 3 of EN/IEC 62061 and PL e of EN ISO 13849-1, they also meet UL and CE requirements. Designed to protection type IP65, the pushbutton is released by turning it to the left or right. A black stripe around the shaft is covered when the mushroom-type pushbutton is operated, thereby indicating the switch position.
