E2ER/E2ERZ

Features

Oil-resistant Proximity Sensors with standard detection and with chip-immune function for withstanding of cutting oil to reduce failures in machine tools and automotive applications area

  • Fluororesin (PUR) cable that withstands cutting oil
  • A sealing method that eliminates gaps at cable joints and the resin filling work together to block ingress of cutting oil
  • IP67G is the degree of protection which is defined according to the Japanese Industrial Standards JIS C0920

1. Models with 5-m cable length are also available with “5M” suffix. (Example: E2ER-X2D1 5M)

2. Models with 5-m cable length are also available with “5M” suffix. (Example: E2ERZ-X2D1 5M)

3. Use the Sensor within the range in which the setting indicator (green LED) is ON (except D2 Models).

4. The response frequency is an average value.
Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance.

5. Use the Sensor within the range in which the setting indicator (green LED) is ON (except D2 Models).

6. The response frequency is an average value.
Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance.
