Pepperl+Fuchs 5V SJ3,5-S1N SIL 3 Inductive Slot Proximity Sensor switch
Pepperl+Fuchs offers innovative, high quality inductive sensors to meet the needs of the worldwide automation and process control markets
the reference target, ferromagnetic metals can also be used as actuator elements. With a variety of approvals for use in hazardous areas, the
sensors are equipped for global use.
In combination with a safety switch amplifier from Pepperl+Fuchs, e.g. KFD2-SH-EX1, use in safety-related applications up to SIL 3 is possible.
The sensor can also be used in applications up to SIL 2 with safety-related NAMUR switch amplifiers.
