E3Z-G
Grooved-type Photoelectric Sensor
■ Grooved design eliminates the need for optical
axis adjustment.
■ Two-axis models also available.
■ Ideal for detection and positioning for cranes and
conveyor systems in automated warehouses.
Ordering Information
■ Sensor Unit
Note: Models with a 0.5-m cable are available. When ordering, specify the cable length by adding the code “0.5M” to the model number
(e.g., E3Z-G61 0.5M).
