WEATHER PROOF CHARACTERISTICS

item

test condition

cold proof

After testing at -25° ± 2°C for 96 hours, the

encoder will be allowed to stand under normal

temperature and humidity conditions for 1 hour.

Measurements will be made within 1 hour after

that. Condensation will be eliminated.

hot proof

After testing at 85° ± 2°C for 96 hours, the

encoder will be allowed to stand under normal

temperature and humidity conditions for 1 hour.

Measurements will be made within 1 hour after

that.

moisture resistance

After testing at 40° ± 2°C, 90 ~ 95% RH for 96

hours, the encoder will be allowed to stand

under normal temperature and humidity

conditions for 1 hour. Measurements will be

made within 1 hour after that. Condensation

will be eliminated.

temperature cycling

After 5 cycles of the following conditions, the

encoder will be allowed to stand under normal

temperature and humidity conditions for 1 hour.

Measurements will be made within 1 hour after

that. Condensation will be eliminated.

salt mist

The encoder will be checked after the following

test:

1) Temperature: 35 ± 2°C

2) Salt solution: 5 ± 1% (solids by mass)

Immersion time: 5 minutes

3) After immersing, salt deposit will be removed

by running water.

4) Duration: 2 hours

evaluation standard

After test:

Contact resistance: 5

Ω max.

Insulation resistance: 10 M

Ω min.

The performance requirements

specified in Electrical

Specifications will be satisfied.

No corrosion will be recognized in

the metal sections of the encoder.
