ORDER GUIDE
Note 1: The sensing range of the retroreflective type sensor is specified for the RF-230
NOTE: Mounting bracket is not supplied with the sensor. Please select
Type
reflector.
Further, the sensing range is the possible setting range for the reflector. The sensor
can detect an object less than 0.1m away (CX-28IR : 50mm).
