Robust Photoelectric Sensor RX (Discontinued Products)

• The self-diagnosis output does not incorporate a shortcircuit protection circuit. Do not connect it directly to a power supply or a capacitive load.

• The tightening torque should be 1.17 N·m or less.

• Do not use during the initial transient time (50 ms) after the power supply is switched on.

• Please take care of the following points when detecting materials having a gloss.

[1] Make L, shown in the diagram, sufficiently long. [2] Install at an angle of 10 to 30 degrees to the sensing object.

• If a shiny object is covered or wrapped with a transparent film such as those described below, the retroreflective type sensor with polarizing filters may not be able to detect it.
  In that case, follow the steps given below.

Example of sensing objects

• Can wrapped by clear film
• Aluminum sheet covered by plastic film
• Gold or silver color (specular) label or wrapping paper

Steps

• Tilt the sensor with respect to the sensing object while fitting.
• Reduce the sensitivity.
• Increase the distance between the sensor and the sensing object.

• Always connect the sensor to the power supply through a load. If the sensor is connected to the power supply directly, the short-circuit protection makes the sensor inoperable. (The output stays in the OFF state and no indicator lights up.) If this happens, connect the sensor to the power supply through a load.
  Further, note that the sensor will be damaged if the power supply is connected in reverse without a load.

• Do not connect sensors in series (AND circuit).

• The residual voltage of the sensor is 4 V. Before connecting to a relay, be aware of the actuation voltage of the relay.
  (Not all 12 V relays may be connected as the load.)

• Connect the junction connector securely as shown below. The tightening torque should be 0.98 N·m or less.
