Two convenient digital screens
Two digital screens are provided, which allow you to check the reference value and the amount of light incident at the same time, and make various settings, which provides extremely high operability.
Various control functions are available to effectively reduce costs
While maintaining the original functions and performance of the FR-J16 series products, the cost of the products has been effectively reduced through structural optimization and the introduction of automated production, effectively improving the cost performance of the products.
Simple and clear button design
The reference value adjustment and switch are operated by buttons, and the functions that are not frequently used are set and operated through the built-in function menu.
Adjustable light output for stable detection of tiny objects and transparent objects
When the light level reaches saturation during close-range detection, transparent objects, or small objects, the sensor’s light output can be reduced to achieve stable detection.
Key lock function to prevent erroneous operation
Prevents operators from changing the reference value by mistake.
Outlet mode
Lead-out type (with two-meter bending-resistant cable as standard).
