Built-in Power Supply Photoelectric Sensor
E3JKFeatures:Long sensing distance that is approximately 8 times that of our conventional model (for the Through-beam and Diffuse-reflective models).
(Through-beam: 40 m, Retro-reflective: 7 m, and Diffuse-reflective: 2.5 m.)
Improved visibility:
• A red LED that makes the spot visible.
• Large indicators that can be seen even from a distance.
Improved operability.
(Enlarged sensitivity adjuster and operation selector)
Freely selectable power supply input (24 to 240 VDC, 24 to 240 VAC).
(Additional types added to the DC type lineup.)
Models with infrared LEDs are also available.
