E3JK
1E3JK
All voltage photoelectric sensors
E3JK
• Built-in amplifier accepts wide supply
voltage range.
• Slim, space-saving construction measures only 50 x 50 x 17.4 mm.
• Relay outputs with long life expectancy and high switching capacity (3 A,
250 V AC).
• Polarized retroreflective type available
for glossy or shiny object detection.
* The value within the parentheses indicates the sensing distance applied when the E39-R2 reflector is used.
Note: The UL-listed model ends with "-US". (Example: E3JK-5M1-US). Note that the DC transistor type of the E3JK is UL-unlisted.

* Values in parentheses indicate the minimum required distance between the sensor and reflector.
Note: When the reflector used is other than the supplied one, set the sensing distance to about 0.7 times of the typical example as a guideline.
