E3JK

All voltage photoelectric sensors

E3JK

• Built-in amplifier accepts wide supply

voltage range.

• Slim, space-saving construction mea-

sures only 50 x 50 x 17.4 mm.

• Relay outputs with long life expectan-

cy 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.

Reflectors

* 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.
