It is recommended to mount the shear droop surface (punch side) of the mounting plate (metal plate) with "GP2A231LRSA". 2. Mounting workability, shaking after mounting and mounting strength depend on the corner radius of the mounting plate and the state of punching. Determine the mounting dimensions after check on an actual machine. 3. General dimensional tolerances shall be ±0.1 mm. ■ Precautions for Use 1. In order to stabilize power supply line, connect a by-pass capacitor of more than 0.33µF between VCC and GND near the device. 2. For cleaning Acryle resin is used as the material of the lens surface. As to cleaning, this refractive type photointerrupter shall not clean by cleaning materials absolutely. Dust and stain shall clean by air blow, or shall clean by soft cloth soaked in washing materials. 3. The connector should be plugged in / out at normal temperature.
