Specifications

Ratings / Characteristics of DC Switching Models

Note: 1 . For stable sensing distance in detail, please refer to ”Engineering Data”

2 . Typical sensing distance corresponds to 80 % of the max. sensing distance.

3 . The enclosure rating IP67 of OMRON internal standards correspond to stricter test requirements than the standard IEC 60529 (refer to chapter “Precautions”)

4 . For other cable materials (e.g. PUR) please contact your OMRON sales representative.

5 . Material-specification for stainless steel housing case: 1.4305 (W.-No.), 303 (AISI), 2346 (SS). For other stainless steel materials please contact your OMRON

sales representative.

6 . Please contact your OMRON sales representative for the availability of stainless steel BGS types.

7 . with slit E39-ES18

8 . PNP models -B4: Vcc to Vcc -2.5 V: Emitting OFF (Source current: 3 mA max.) / Open or 0 to 2.5 V: Emitting ON (Leakage current: 0.1 mA max.)

NPN models -C4: 0 to 2.5 V: Emitting OFF (Source current: 3 mA max.) / Open or Vcc to Vcc -2.5 V: Emitting ON (Leakage current: 0.1 mA max.)
