Detecting grains in resin-molded products

Detecting grains in resin-molded products

Using fiber sensors to detect the grains in a molded product makes it possible to determine whether a resin-molded product has been assembled correctly.
Because the grains are only about Φ4 mm, attaching the small spot lens NF-DA02 to the fiber unit allows for a smaller detection spot for easier differentiation. With no grains, the product will be nearly transparent, allowing for easy transmission of light. With grains, however, the light is diffused, increasing the received light amount and ensuring reliable detection. At a sensing distance of 15 mm, the NF-DA02 has a spot size of Φ1.4 mm, larger than that of a normal lens for more reliable identification of diffuse light and improved detection stability.

Controlling drill bit direction

Controlling drill bit direction

The screen fiber unit NF-TZ07 can determine whether drill bits are correctly positioned during transferring.
With 32 mm width light screen, the NF-TZ07 can detect variations in the received light amount  due to differences between tip and end of a drill bit, enabling reliable direction detection.

Model: Screen Fiber Unit  NF-TZ07




Positioning Automotive Components

Positioning Automotive Components

The BGS-HDL series is used for positioning during automotive component assembly.
Detecting holes at an angle is difficult with photoelectric sensors, but The BGS-HDL series allows for stable detection, even when mounting is only possible diagonally, by using "AUTO mode" to always detect with the optimal sampling period.

Shaft Direction and Motor Float Detection

Shaft Direction and Motor Float Detection

Using the BGS-HDL series makes it possible to determine the direction of an actuator shaft and to detect floating (flange detection) when a motor is attached.
With two control outputs, the BGS-HDL series is capable of separate detections by using Output 1 for determining the shaft direction, and using Output 2 for motor float.
This means that all the work in applications that would conventionally require two sensors can be done with just a single sensor.
