Note :
The retroreflective types (CX-39A and CX-39B) include the CX-39A-Y and CX-39-B-Y types that do not come with an RF-230 reflector as an accessory. For these types, order the CX-491-Y type which is the CX-491 type without reflective mirror.
Sensor
Notes :
1) Not incorporated on the emitter of the thru-beam type sensor.
2) It is the power indicator (red) on the emitter of the thru-beam type sensor.
