Inductive Proximity Sensors
E57 Two-Wire (AC, AC/DC, DC) Proximity Sensors
Recommended Mounting Clearances
For unshielded standard range sensors and extended range sensors, clearance must be provided
around the sensor when mounting for reliable performance. (“Sn” is the sensing range of the
sensor, “d” is the sensor diameter.)
E57 Premium Sensors, Mounting
Wiring Diagrams
Pin numbers are for reference, rely on pin location when wiring.
