Fine Tuning Fiber Photoelectric Sensor E3X-NH
High-precision Sensing with Auto- and
Manual-tuning
Solves All the Problems of Conventional Models
Suitable for high-precision positioning using the
fine sensitivity adjustment function.
Manual-tuning allows threshold adjustments while
sensing objects are moving.
Operation conditions can be seen at a glance
through the incident level indicators and threshold
indicators.
Auto-tuning feature incorporates an automatic
sensitivity compensation function ensuring an
optimum margin for changes in sensing objects or
ambient environments.
Offers the longest sensing distance.
Newly added mark-sensing models (blue LED).
