SERIES LED Collimated Beam Sensor LED Collimated Beam Type Which Is as Accurate as a Laser Sensor, but Much Safer. Outer Diameter Measurement Marked Conforming to EMC Directive Compact Size Safe Red LED Beam Simple Beam Alignment Its emitter and receiver are much smaller compared to those of the amplifier built-in type (LA-510). Hence, they can be installed even in a narrow space inside an automatic assembly machine, etc. Since a red LED, harmless to your eyes, has been incorporated as the beam source, you are free from strict laser safety regulations. Moreover, due to the red LED beam source, the measuring spot is visible, which makes positioning of the object simple. Beam alignment is easy by using the target label (accessory). Further, the 3-stage stability indicators on the amplifier indicate the incident beam level at a glance.

For the analog output, in addition to the span adjustment function, a convenient shift function which enables the analog voltage to be shifted by0.5V has been incorporated. Example: To shift the analog voltage from 2.51V to 3.00V with a certain amount of beam interruption 576 Before adjustment After adjustment Darkest condition 1.00V 1.49V Setting condition 2.51V 3.00V Lightest condition 5.00V 5.49V After adjustment 5.00 1.49 1.00 Before adjustment 0 Interrupted width Darkest Sensing object 5.49 Lightest The timing and the effective duration of the comparative outputs can be controlled by an external input.

Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous parts of machinery. It is a normal object detection sensor. Mounting Sensor heads * The projected LED beam has a directionality. Hence, take care of emitter and receiver mounting direction. LA-310 LA-305 Receiver Receiver 2-mounting holes Emitter Emitter Receiver Outer Diameter Measurement LD LA-300 Emitter Beam alignment * Make sure that at least one stability indicator lights up when you supply power to the amplifier connected with sensor heads. While aligning sensor heads, if more stability indicators light up, more reliable detection can be obtained. * Beam alignment should be performed prior to any adjustments on the amplifier. * If the bottom face and the side face of the emitter and the receiver are mounted on the same plane surfaces, or if the front faces of the emitter and the receiver of LA-305 are kept parallel and their top face and side face are mounted on the same plane sufaces, beam alignment need not be done. * If mounting is not possible on the same plane surfaces, affix the target label (accessory) on the front surface of the receiver and adjust so that the emitted beam is incident at the center of the crosshair. After the alignment, peel off the target label. * If either sensor head moves out of position, do the beam alignment and then the amplifier adjustment also again.

Sensing object However, even a simulated center is easily obtained by shift adjustLight ment without any realignment. beam Note: To make the whole beam balanced between the lightest and the darkest conditions, the sensor heads should be positioned where the sensor generates 3V analog output. Adjusting HIGH & LOW output levels (two independent outputs) HIGH output threshold level LOW output threshold level * Again, block as little of the beam for which you want the LOW output. Turn the LOW adjuster to just before the point where the LOW operation indicator lights up. The threshold level increases as the adjuster is turned clockwise. High Analog voltage * Block as much of the beam for which you want the HIGH output. Turn the HIGH adjuster to just before the point where the HIGH operation indicator lights up.

This can cause malfunction due to induction. Others * The sensor's output is proportional to the amount of the LED light received. Since there is some variation in the light intensity at the center and the periphery of the sensing area, take care that `outputdimension' may not hold. * For stable operation, use the sensor 10 min., or more, after switching on the power supply. * Avoid dust, dirt, and steam. * Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. * Keep the front faces of the sensor heads free of dust, dirt, metal powder, etc. Should the faces be covered with it, deteriorating its performance, wipe them clean with a soft cloth or blown air. * Take care that the sensor head is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance. Note: Either HIGH or LOW setting can be made first. 583 LD Span adjustment 1 Block the whole beam to enter into the darkest condition and set the output at 1V with the shift adjuster. 2 Allow the whole beam to be received to enter into the lightest condition and set the output at 5V with the span adjuster. 3 For more accurate calibration, repeat 1 and 2.
