Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of "Caution", "Warning" or "Danger". They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations. - Page 4 Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
- Page 5 ■Operators (1) This Operation Manual is intended for persons who perform assembly, operation and maintenance or inspection of machinery using pneumatic equipment with sufficient knowledge and experience with such equipment. Only such persons are allowed to perform assembly, operation and maintenance or inspection. (2) Read and understand this Operation Manual carefully before performing assembly, operation and maintenance or inspection.
- Page 6 Caution ■Do not touch the terminals or connectors when energized. Otherwise, an electric shock, malfunction or damage to the product may result. ■After completing maintenance or inspection, perform appropriate functional inspections. Stop the operation in the event of an abnormality such as when the equipment does not operate properly. Otherwise, safety may not be ensured due to an unexpected malfunction.
- Page 7 (4) Take precautions when multiple cylinders or actuators are used close together. When using two or more cylinders or actuators with a built-in magnet in close proximity to each other arranged in parallel, design so that they will maintain a separation distance of at least 40 mm. (If the separation distance is specified for each of cylinder/actuator series, use that value.) The accuracy of the analogue ASW may be reduced and it may malfunction due to the magnetic field interference between them.
- Page 8 Mounting and Adjustment Caution (1) Do not drop or apply an impact. Otherwise, components inside the product may be damaged, resulting in malfunction of the product. (2) Observe the tightening torque for mounting. If tightened at a torque higher than the specified torque range (0.15 to 0.25 N·m), the cylinder/actuator body, mounting screws, mounting brackets, and product body, etc.
- Page 9 Operating Environment Warning (1) Do not use in an environment where there is explosive gases or dustpresent. The analogue ASW and the sensor monitor are not explosion proof. Fire or an explosion may result. Caution (1) Do not use in a place where magnetic fields are generated. Using the product in such a place may cause a malfunction or deterioration in the accuracy of the product.
- Page 10 Maintenance Warning (1) Removal of equipment and supplying and exhausting the compressed air When removing the equipment, first confirm that measures, such as drop prevention for driven objects and safe lock out, are in place, shut off the air supplied and power supply of the facilities, and exhaust the compressed air inside the system.

Page 16: Mounting And Installation
Mounting and Installation ■Installation method ○Analogue auto switch When mounting the analogue auto switch to the cylinder/actuator, a mounting bracket corresponding to the cylinder/actuator should be used. The mounting method depends on the cylinder/actuator type and tube inner diameter. When mounting a new sensor, confirm that the cylinder/actuator is of the built-in magnet type and then prepare a mounting bracket corresponding to the cylinder/actuator. - Page 17 ○Mounting with panel mount adapter ●Mount part (a) to the front of the body and fix it. Then insert the body into the panel until (a) comes into contact with the panel front surface. Next, mount part (b) to the body from the rear of the panel and insert it until (b) comes into contact with the panel where (b) is fixed.

Page 22: Analogue Auto Switch Overview
Analogue Auto Switch Overview When a power voltage is supplied to the analogue ASW, it outputs an analogue voltage of 1 to 5 V according to the magnetic force of the magnet built in the cylinder/actuator. By mounting an analogue ASW on the actuator and reading the analogue output value, the position of the magnet can be detected. - Page 23 ○High resolution range The range where the angle of the analogue output waveform to the stroke is 0.2 [V/mm] or more in the above determinable range of an analogue output waveform is considered as the high resolution range. As long as it is within the high resolution range, a stroke difference of about ±0.1 mm can be distinguished.
- Page 24 ○Full-stroke detectable actuator An actuator in which the full stroke is smaller than the determinable range is considered as a full-stroke detectable actuator. By mounting an analogue ASW so that the mid point of the stroke and that of the determinable range (approximately 3 V output) match, the entire stroke of the actuator can be determined with one unit of analogue ASW.
- Page 25 ○Mounting an analogue auto switch •Full-stroke detectable actuator With a full-stroke detectable actuator, by mounting the analogue ASW at the recommended position, the position can be determined throughout the entire stroke. •Other actuators Adjust the analogue ASW position so that the point that needs to be detected (workpiece gripping position, etc.) will be close to the centre (approximately 3 V output) of the determinable range.
