Proximity Sensors Technical Guide

The following conditions must be considered to understand the conditions of the application and location as well as the relation to control 

equipment.

Model Selection

* mT (millitesla) is a unit for expressing magnetic flux density. One tesla is the equivalent of 10,000 gauss.

Influence of 
external 
electromag-
netic fields

The influence within a DC magnetic field is 20 mT

*

 max. Do not use the Sensor at a level higher than 20 mT.

Sudden changes in the DC magnetic field may cause malfunction. Do not use the Sensor for applications that involve turning a 
DC electromagnet ON and OFF.

Do not place a transceiver near the Sensor or its wiring. Doing so may cause malfunction.

Other con-
siderations

Cost feasibility: Price/delivery time

 Life: Power-ON time/frequency of use

Check the relation between the sensing object 
and the Proximity Sensor.

Material, distance 
to Sensor, orien-
tation, etc.

sit point, allowable 
error, etc.

Sensing (set) distance, shape of Sensor (rectangular, cylindrical, through-
beam, grooved), influence of peripheral metal (Shielded Sensors, Non-
shielded Sensors), response speed (response frequency), influence of 
temperature, influence of voltage, etc.

Verify the electrical conditions of the control system 
to be used and the electrical performance of the 
Proximity Sensor.

The environmental tolerance of the Proximity Sensor 
is better than that of other types of Sensors. However, 
investigate carefully before using a Proximity Sensor 
under harsh temperatures or in special atmospheres.

Water Resistance

Do not use the Sensor in water, rain, or outdoors.

Ambient Conditions

To maintain reliability of operation, do not use the 
Sensor outside the specified temperature range or 
outdoors. Even though the Proximity Sensor has a 
water-resistant structure, it must be covered to pre-
vent direct contact with water or water-soluble cutting 
oil. Do not use the Sensor in atmospheres with chem-
ical vapors, in particular, strong alkalis or acids (nitric 
acid, chromic acid, or hot concentrated sulfuric acid).

Explosive Atmospheres

Do not use the Sensor in atmospheres where 
there is a danger of explosion. Use an Explosion-
proof Sensor.

Temperature 
and humidity

Highest or lowest 
values, existence 
of direct sunlight, 
etc.

Temperature influence, 
high-temperature use, 
low temperature use, 
need for shade, etc.

Atmosphere

Water, oil, iron 
powder, or other 
special chemicals

Need for water resis-
tance or oil resistance,
need for explosion-
proof structure

Vibration and 
shock

Size, duration

Need for strength, 
mounting method

When deciding the mounting method, take into consideration not 
only restrictions due to mechanical devices, but also ease of main-
tenance and inspection, and interference between Sensors.

Wiring method, 
existence of in-
ductance surges

Connection

Wires
Wire type, length, oil-resistant 
cable, shielded cable, robot 
cable, etc.

Conduits, ducts, pre-wired, 
terminal wiring, ease of main-
tenance and inspection

Mounting procedure

Installation location

Existence of mounting 
brackets, direct mounting, 
secured with bolts or screws

Ease of maintenance and 
inspection, mounting space
