Reduction factor 1
The perfect sensor is one that is equally suited to all types of applications
and this is the case with reduction factor 1 sensors. They detect all types
of metal with almost the same operating distance. Compared with com-
mon inductive sensors, they offer considerable benefits, in particular for
applications where a sensor must detect different metals.
Benefits:
•
Same operating distance for all metals
•
Maximum operating distance from 2 mm to 75 mm
•
Electric magnetic field immunity
•
Mechanical welding immunity (optional)
•
Complete portfolio of cylindrical and cubic housing designs
Weld-immune sensors
Proximity switches used in welding systems are characterized by their
high immunity to strong magnetic fields and an increased mechanical ro-
bustness suitable for the rough ambient conditions.
They are fitted with a cross-linked PPS front face to provide protection
against spattering weld sparks during welding, and their housing is made
from PTFE-coated brass.
Sensors with a metal face
Metal Face sensors from Pepperl+Fuchs are made of stainless steel for
applications that have particularly high requirements in terms of sensor
robustness. For example, sensors that are used in machine tools are ex-
posed to high forces, abrasion, and aggressive media.
To ensure a long service life, sensors with an active face made from stain-
less steel are used in these applications.
Sensors with e1 certification
Commercial vehicles represent an important application area for sen-
sor technology. Special setups or add-on systems often result in "rolling
machines." Sensors for diggers, cranes, agricultural machinery, refuse,
or fire trucks ares some of the many applications for industrial sensor
technology. Specially adapted products may be required for use in ships
or fork lift trucks.
Here, different and conflicting requirements must all be taken into consid-
eration in the applied components. This includes the various application-
specific boundary conditions that we are familiar with from many applica-
tions in traditional mechanical engineering. In addition to the basic sensor
function, optimal mechanical integration into the overall system is also
required, as well as application-specific sealing of the devices and resis-
tance to temperature and environment influences. In some cases, special
connectors usually found in vehicles may be integrated into the sensors.
Furthermore, the pertinent standards for the vehicles must be taken into
consideration. This includes vehicle or ship-building requirements such
as more stringent EMC requirements. Over recent years, Pepperl+Fuchs
has worked on many customer-specific developments where it has dem-
onstrated its ability to integrate both these requirements into sensors,
both efficiently and cost effectively for high volumes. Many reputable
companies within this sector choose our products.
Due to their robustness, inductive proximity switches in cylindrical hous-
ings are often used for this market. Pepperl+Fuchs also offer inductive
sensors for analog position measurement as well as inclination sensors.
Pressure-resistant sensors
Pressure-resistant proximity switches are suitable for use in hydraulic ac-
tuators.They are suitable for operating pressures up to 500 bar and peak
pressures up to 800 bar on the active area.
The pressure resistance is achieved by means of a ceramic front face
that is an integral part of the stainless steel housing. A groove is also
incorporated into the housing (O-ring).
