workpiece is required with electronic proximity sensors
• Fast switching characteristics; because the output signals are generated
electronically, the sensors are bounce-free and do not create error pulses.
• Wear-resistant function; electronic sensors do not include moving parts which
can wear out
• Unlimited number of switching cycles
• Suitable versions are also available for use in hazardous conditions (e.g. areas
with explosion hazard).
Today, proximity sensors are used in many areas of industry for the reasons
mentioned above. They are used for sequence control in technical installations and
as such for monitoring and safeguarding processes. In this context sensors are used
for early, quick and safe detection of faults in the production process. The
prevention of damage to man and machine is another important factor to be
considered. A reduction in downtime of machinery can also be achieved by means of
sensors, because failure is quickly detected and signalled. 16 © Festo Didactic GmbH & Co. KG •...
