Position switches

Range of application Design and operating principle
Position switches are used where moving parts of machines andindustrial plants have to be positioned,controlled and monitored.The various application fields,ranging from fine mechanics toheavy-duty machinery,require differentmaterials,electrical capacityand quality criteria regarding construction and design. Many of the position switches fulfil the requirements of the IEC60947-5-1 standard and can therefore also be used as position switches with safety function.These products are identified by thesymbol A for positive break.Some position switches fulfil the requirements for standardisedswitches to DIN EN 50 047.The position switches are available withsnap and slow action and can be supplied with a metal roller on re-quest.A large variety of actuators complete the program.The devices are listed in the order of enclosure dimensions andmaterials,starting with the smallestand the plastic enclosures.All position switches shown in this chapter bear the CE mark acc-cording to the low Voltage Directive 73/23/EC. 85 85 Application Position monitoring on a industrial conveyor belt As a piece industrial counter Legend Actuating angle from bottom ofswitch axis as shown in picture Actuating angle from right of switch axis Actuating angle from left of switch axis as shown in picture
