Technical information General characteristics The position switches are ERSCE s main product, and are the result of more than 4 years of experience in industrial automation. They are suitable for use in the most different environmental conditions, thanks to their solid construction, IP66 certified, and proven reliability over decades of fieldwork. thermoplastic or metal body IP66 contact blocks with positive opening of the NC contact according to IEC EN 6947-5- e VDE 66-2 form conforming to EN 547 (E series) and to EN 54 (E4 series)) Metal heads All the heads are made of metal, to ensure maximum performance and lifetime of the switch. x6 dragging device Rotating heads Possibility to supply, on request, the limit switch lever rotated by 8 steps, and the actuator by 9 steps. lever Adjustable levers Possibility to adjust the lever every, for 6, by moving the lever and the dragging device. Cross Crociera joint Overturning levers Possibility to fasten the lever on the straight or reverse side, maintaining the positive opening of the NC contact. Unidirectional heads The lever can be activated to the left or right only or in both directions by adjusting the cross joint. 92
