Linearity 0.5% F.S. Stable Temperature Characteristics Minute displacement of metallic objects can be accurately measured with a resolution of 0.04% F.S. Displacement is accurately output since it incorporates a high accuracy linearity correction circuit. Sensor head: 0.5!m/C Amplifier: 0.4!m/C There is almost no effect of temperature variations. Incorporates Zero-adjustment Function Suitable for Various Analog Control Devices Choice of Sensor Heads The analog voltage output corresponding to the standard measured value can be forcibly set to 0V (analog current output 4mA). This is useful for an error check by taking the measured master workpiece values as standard. Job change-over can also be smoothly done. Further, the zero-adjustment function can be set not only at the amplifier, but also with an external input, so that setting can be done even from a remote place. It is suitable for various analog control devices since it is equipped with two outputs, analog voltage (0 to 5V) and analog current (4 to 20mA). "5.4mm non-threaded type for 1mm sensing, "8mm non-threaded type and M10mm threaded type for 2mm sensing are available. Further, long range M12 threaded type which can sense up to 5mm and front sensing type which can be embedded in metal and can sense up to 3mm have been newly added to the sensor range. The sensor head can be selected according to the application and the mounting space. The sensor heads have superior environmental resistance as they are protected as per IP67 (IEC) & IP67g (JEM) and, moreover, the cable joint has a protector. Different Frequency Type Also Available In case of GP-A14F type, the standard type and the different frequency type can be mounted next to each other. For models besides GP-A14F type, they can be mounted at 1/3 the interval required for the same frequency types. It is optimally suited for high accuracy measurement, such as, deformation measurement, etc., by being adjacently mounted in a narrow space.

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 head * The tightening torque should be under the value given below. * Make sure to use in combination the sensor head and amplifier which have the same production serial number (5 digit). Since adjustment is done before shipment, if items with different production serial numbers are combined, the sensing characteristics will deteriorate even if they have the same model number. * The length of the sensor head cable cannot be changed. * Make sure to use an M3 or smaller set screw having a cup-point. Linearity in case of disc-shaped or cylindrical objects * In case the sensing object is disc-shaped or cylindrical, the linearity of the analog output varies with the sensing object size. In this case, if the analog voltage output and the analog current output are adjusted to 0V and 4mA, respectively, when the sensor head is in contact with the sensing object, and to 5V and 20mA, respectively, when the sensor head is 2mm [GP-A5S(I): 1mm, GP-A12ML(I): 5mm, GP-A14F(I): 3mm] away from the sensing object, the linearity ( 0.5% F.S.) can be attained if the disc has a diameter of "12mm [GP-A12ML(I): "30mm], or more, and the cylinder has a diameter of "10mm [GP-A12ML(I): "50mm], or more and a length of 50mm. <In case of disc> <In case of cylinder> Mounting with set screw <Non-threaded type> Set screw (M3 or less) (Cup-point) A Model No. A (mm) Tightening torque GP-A5S(I) 0.44Nm 5 or more GP-A8S(I) 0.58Nm Note: Do not apply excess torque.

Do not connect it directly to a power supply or a capacitive load. 6 Low (0 to 1V) (duration 30ms or more): external zero-adjustment setting High (5 to 30V, or open): external zero-adjustment ineffective * The external zero-adjustment input operation is independent of the state of the `button operation effective/ineffective selection switch'. However, since the external zero-adjustment setting is not stored in the EEPROM (memory), it is canceled when the power supply is switched off. In case it is desired to store the setting in the EEPROM, set the `button operation effective/ineffective selection switch' once to the `FREE' side and again to the `LOCK' side, before switching off the power supply. Note: If the power supply is switched on with the external zero-adjustment input terminals (terminal Nos. 5 and 6) short-circuited, since zeroadjustment gets done in the transient state of the power supply switching on, stable sensing is not possible. Further, ensure to apply the zero-adjustment input 30 min., or more, after the power supply is switched on. Others * Do not use during the initial transient time (0.5 sec.) after the power supply is switched on. * Do not use the sensor at places having intense vibrations, as this can cause malfunction. * Avoid dust, dirt, and steam. * Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. * Take care that the sensing face is not covered with metal dust, scrap, etc., as this can cause malfunction. 615 Displacement Sensing Image Sensor VI GP-A Functional description Collimated Beam Sensors LA LA-300 PRECAUTIONS FOR PROPER USE MEASUREMENT SENSORS LA-300 LA Collimated Beam Sensors LD Outer Diameter Measurement GP-A VI Displacement Sensing Image Sensor GP-A PRECAUTIONS FOR PROPER USE Adjustment * This product is delivered after being adjusted with the standard sensing object.

In case they are not, repeat the adjustment from step 4.

The values stored in the EEPROM are not erased even when the power supply is switched off. However, kindly note that the EEPROM has a life span and its guaranteed life is 100,000 write operation cycles. Notes: 1) The set values are not stored in the EEPROM if the power supply is switched off when the switch is on the `FREE' side. 2) If the switch is set to the `LOCK' side before adjustment, the set values cannot be changed. 616 MEASUREMENT SENSORS GP-A DIMENSIONS (Unit: mm) Sensor head Amplifier 17 Collimated Beam Sensors LA LA-300 All models "2.5 high frequency coaxial cable 3m long 7 Connector 6.2 "6.4 17 25.7 "5.4 (100) 90 GP-A8S(I) "2.5 high frequency coaxial cable 3m long Connector 6.2 53 (119) 6.5 "6.4 Suitable for 35mm width DIN rail Outer Diameter Measurement 17 2 17 "8 Connector for sensor head connection 25.7 GP-A10M(I) 67 17 6.2 "2.5 high frequency coaxial cable 3m long 3 19.8 Displacement Sensing Image Sensor VI GP-A 14 Connector "6.4 17 Cover removed condition 25.7 "18 M101 Toothed lock washer (internal tooth) Power indicator (Green) 2-"5 mounting holes GP-A12ML(I) Over indicator (Orange) 2-"8.2 21 17 39 "2.5 high frequency coaxial cable 3m long 6.2 7 5 Alarm indicator (Yellow) 6 7 8 Connector 76 "6.4 "10.1 17 25.7 M121 3.5 "21 1 2 3 4 Toothed lock washer (internal tooth) Shift-down button GP-A14F(I) Shift-up button Zero-adjustment button Span adjuster 5.4 Button operation effective/ ineffective selection switch "2.5 high frequency coaxial cable 3m long 34 27.5 7.5 Connector 8 15 "6.4 17 25.7 2-countersunk mounting holes for M3 Center of sensing MS-SS5 MS-SS8 Mounting bracket for GP-A5S(I) (Optional), mounting bracket for GP-A8S(I) (Optional) 2 -"3.5 mounting holes Model No. C MS-SS5 MS-SS8 18 20 Item A A B B 10 11 4 C 8.3 10.3 4 8 16 4 D LD GP-A5S(I) D 6.1 6.5 Applicable model GP-A5S(I) GP-A8S(I) Material: Nylon 66 617
