Schneider Electric XCE & XCJ Limit Switches

Electromechanical detection
 
Limit switches are used in all automated installations and also in a wide variety of applications, due to the numerous advantages inherent to their technology. They transmit data to the logic processing system regarding:
presence/absence,  
passage,
positioning,
end of travel.
Simple to install switches, offering many advantages
From an electrical viewpoint:
galvanic separation of circuits,
models suitable for low power switching, combined with good electrical durability,
very good short-circuit withstand in coordination with appropriate fuses,
total immunity to electromagnetic interference,
high rated operational voltage.
From a mechanical viewpoint:
N/C contacts with positive opening operation,
high resistance to the different ambient conditions encountered in industry,
high repeat accuracy, up to 0.01 mm on the tripping points,
simple visible operation.
Mechanical endurance
Major factors affecting the mechanical endurance of a limit switch:
operating speed and frequency,
operating travel (percentage of total travel),
cam angle,
environment (presence of abrasive dust, corrosive substances, etc)
