Sensor Reflector or reflective tape

Notes 1) Be sure to align the beam axis when mounting the sensor and reflector or reflective tape. Use of the RF-210 reflector or RF-11 reflective tape
requires more precise adjustment than when the RF-230 reflector supplied with the product is used. Mount the reflector / reflective tape in
such a way that the sensor angle can be adjusted in a wide range. For the sensor angle adjustment and reflector / reflective tape position
adjustment, refer to “PRECAUTIONS FOR PROPER USE” on pages 20 and 21.
2) Sensing range A may vary depending on the shape of the sensing object. Be sure to check the operation with the actual sensing object.
3) Do not press the reflective tape RF-11 and RF-12 strongly because they have soft surfaces. The internal prism may be crushed and the
reflection distance may be reduced. Also, do not cut the tape before use. Performance will not be maintained.
