Proximity Sensors Technical Guide

●Operating Environment

Water Resistance

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

Ambient Conditions

Do not use the Sensor in the following environments.

Doing so may cause malfunction or failure of the Sensor.

1. To maintain operational reliability and service life, use the Sensor

only within the specified temperature range and do not use it

outdoors.

2. The Sensor has a water resistant structure, however, attaching a

cover to prevent direct contact with water will help improve

reliability and prolong product life.

3. Avoid using the Sensor where there are chemical vapors,

especially strong alkalis or acids (nitric acid, chromic acid, or hot

concentrated sulfuric acid).

●Maintenance and inspection

Periodic Inspection

To ensure long-term stable operation of the Proximity Sensor, inspect

for the following on a regular basis. Conduct these inspections also

for control devices.

1. Shifting, loosening, or deformation of the sensing object and

Proximity Sensor mounting

2. Loosening, bad contact, or wire breakage in the wiring and

connections

3. Adherence or accumulation of metal powder

4. Abnormal operating temperature or ambient conditions

5. Abnormal indicator flashing (on setting indicator types)

Disassembly and Repair

Do not under any circumstances attempt to disassemble or repair the

product.

Quick Failure Check

You can conveniently check for failures by connecting the E39-VA

Handy Checker to check the operation of the Sensor.
