Technical Data and Specifications
E57P Performance 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.)
