1 LA- SERIES LED Collimated Beam Sensor LA LA- HL-T1 LM1 LH-5 HL-C1 Compact size Its emitter and receiver are much smaller compared to those of the amplifier built-in type (LA-51). Hence, they can be installed even in a narrow space inside an automatic assembly machine, etc. Long sensing range type / LA-1 Slim type / LA-5 : WHD5 mm W.77H.77D1.77 in : WHD5 mm W.77H.77D1.7 in : W1HD1 mm W.79H1.575D.9 in : W1HD1 mm W.79H1.575D.9 in Two comparative outputs plus one analog output In addition to 1 to 5 V analog output, two comparative outputs (, ) have been incorporated. The timing and the effective duration of the comparative outputs can be controlled by an external input. (Either edge trigger or gate trigger is selectable.) Safe red LED beam 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. Span & shift adjustment LED collimated beam type which is as accurate as a laser sensor, but much safer. Conforming to EMC Directive Simple beam alignment Beam alignment is easy by using the target label (accessory). Further, the -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 by.5 V has been incorporated. Example: To shift the analog voltage from.51 V to. V with a certain amount of beam interruption Sensing object Light beam Before adjustment After adjustment Darkest 1.

LA-1 This product is not a safety sensor. 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 holes Note: When carrying out high accuracy sensing with LA-5, install the mounting bracket on the front face as shown in the above figure. <Mounting on DIN rail> 1 Make sure that the mounting stopper is latched inside. Hook the front side of the controller mounting section on the 5 mm 1.7 in width DIN rail. Snap the controller down on the 5 mm 1.7 in width DIN rail. m To remove, insert a minus screwdriver into the mounting stopper and pull out. <Mounting with screws> Use two commercially available M screws. The tightening torque should be 1. Nm or less. LA-5 The tightening torque should be.5 Nm or less.

SPAN Mounting stopper Minus screwdriver M screw Please arrange separately. 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-5 are kept parallel and their top face and side face are mounted on the same plane surfaces, 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. LA-1 To obtain optimum beam alignment, use a voltmeter and adjust the position to obtain the peak analog output signal from the amplifier.

8 PRECAUTIONS FOR PROPER USE Calibrating analog output The analog voltage output relates to the span and the shift adjustments as in the figure below. How to calibrate the output into 1 to 5 V Analog output 5 V 1 V Darkest Shift adjustment Explanation (e.g.) Wire detection Wire Light beam Span adjustment A B C Incident light intensity Lightest Further use of shift adjuster If you want to change the output voltage value after the calibration, the shift adjuster enables you to shift the analog voltage up or down within about.5 V. (e.g.) To shift the analog voltage from.51 V to. V with a certain amount of beam interruption Light beam Darkest 1. V 1.9 V Setting.51 V. V Sensing object Lightest 5. V 5.9 V Application: When two sensor heads are used to measure the width of a sheet, the shift adjuster can eliminate the need to move the sensor heads during set-up. Reference width Sensing object Light beam Note: To make the whole beam balanced between the lightest and the darkest s, the sensor heads should be positioned where the sensor generates V analog output. Adjusting & output levels (two independent outputs) output threshold level Block as much of the beam for which you want the output. Turn the adjuster to just before the point where the operation indicator lights up. The threshold level increases as the adjuster is turned clockwise. output threshold level Again, block as little of the beam for which you want the output. Turn the adjuster to just before the point where the operation indicator lights up. The threshold level increases as the adjuster is turned clockwise. Incident beam widthac Interrupted beam widthb Lightest : The entire beam is received. Darkest : The entire beam is interrupted. Note: Either or setting can be made first. 1 Block the whole beam to enter into the darkest and set the output at 1 V with the shift adjuster. Allow the whole beam to be received to enter into the lightest and set the output at 5 V with the span adjuster. For more accurate calibration, repeat 1 and. Before adjustment After adjustment Up to now, the sensor heads have had to be located at the exact positions with respect to the reference object to obtain a V (center of 1 to 5 V) sensor analog output. However, even a simulated center is easily obtained by shift adjustment without any realignment. High Analog voltage (Under-dark) output level (Over-dark) output level Low Darkest Comparative ON output () OFF Comparative ON output () OFF Lightest Incident light intensity LA- The external synchronization input controls the timing or the effective duration of the two comparative outputs. Either edge or gate trigger is selectable. External synchronization selection switch Sensing signal External synchronization signal Voltage between ( ) ES and ES ON OFF High Low ON Comparative outputs (, ) OFF Gate trigger ON OFF High Low ON OFF Edge trigger ms approx. input signal: Low... to 1 V, High...V or open Note: If external synchronization is not used, set the external synchronization selection switch on Gate trigger and short-circuit the external synchronization inputs (ES and ES). Wiring Make sure that the power supply is off while wiring. Verify that the supply voltage variation is within the rating. If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of the sensor head or the amplifier connect the frame ground (F.G.) terminal of the equipment to an actual ground. Do not run the wires together with high voltage lines or power lines or put them in the same raceway. 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 1 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. 951 HL-C1 LA LA- HL-T1 LM1 LH-5
