Radial Cross Ray Method The transmitter emits light beams in a scanning manner and receiver accepts light beams of all axes at all times. When eam is emitted, all of the receiving elements of the receiver receive the light. The sensor is activated when light beam of any of the light axes is blocked. Transmitter 4 Receiver The figure on the right shows a model with six light axes. The number of light axes depends on the model. 6

3 Input/Output Circuit and Connection Transmitter Receiver Internal circuit Internal circuit The output transistor turns off when load short circuits or overload occurs. Check the load and turn the power back on lue rown Lead color lue lack rawn V DC V V Output DC V Setting Install the transmitter and receiver face-to-face. Swivel the transmitter and receiver vertically and horizontally to install them at the center of the area in which the operation indicator (orange LED) is illuminated for the individual direction. The tightening torque for installing the sensor (with M4 screws) should be up to.6 N m. Displacement in the direction may be up to ±mm. Displacement in the direction should be within ±mm. If the transmitter and receiver are too closely installed to each other or light axes are misaligned, the output may be unstable. When the light axes are aligned, the operation returns to normal. ny reflecting object (wall, floor, machine, etc.) within the effective range between the transmitter and receiver may allow the light of the sensor to go around the detection object, which is supposed to block the light, and reach the receiver. Choose the installation location carefully. ny glossy object such as a coated surface in the surrounding area must be at least mm away for the distance setting of within m and mm away for the distance setting of over m. Use caution with interference when installing sensor adjacently. Detection object Reflecting object For Correct Use e sure to follow the instructions in the operation manual provided for correct use of the product. This sensor cannot be used as a press safety device or other safety device for protection of human body that requires conformity to domestic or overseas standards or certification concerning protection of human body. Use for such purposes may lead to death or serious injury in the unlikely event of failure. This sensor is intended for detection of ingress of human body or object passing through an arbitrary point not involving protection of human body or safety. When using this sensor for safety purposes, ensure safe operation of the system as a whole including detection and control.
