Page 3 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 SMC develops, designs, and manufactures products to be used for automatic control equipment, and provides them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not allowed. Products SMC manufactures and sells cannot be used for the purpose of transactions or certification specified in the Measurement Act of each country.
Page 5 Operator This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.
Page 6 Cylinders or actuators include cylinders, air grippers, rotary actuators, and electrical actuators/cylinders. Hereafter, an “2-in-1 auto switch” is stated as an “2-in-1 ASW”. Design/Selection 1. Confirm the specifications. If the product is used with excess load applied or beyond the specification range, this may cause the product to be damaged or malfunction.
Page 7 12. Pay attention to leakage current. <2-wire type> When in the OFF state, a current (leakage current) flows to the load to operate the internal circuit. Load operating current (OFF condition) > Leakage current If the above criteria is not satisfied, the auto switch will not reset correctly (stays ON). Use a 3-wire auto switch if this specification cannot be satisfied.
Page 8 Wiring 1. Check the insulation of the wiring. If there is any poor insulation (contact with other circuits, grounding fault, or poor insulation between terminals, etc.) an over-current flows in, causing damage to the auto switch. 2. Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit.
Page 9 Operating Environment 1. Never use in an atmosphere containing explosive gases or dust. Auto switches are not explosion-proof. This may cause an explosion. 2. Do not use in an area where a magnetic field is generated. Auto switches will malfunction or magnets inside cylinders/ actuators will become demagnetized. 3.
Page 10 Maintenance 1. Perform the following maintenance periodically in order to prevent possible danger due to unexpected auto switch malfunction. 1) Secure and tighten auto switch mounting screws. If screws become loose or the mounting position is dislocated, retighten them after readjusting the mounting position.

Page 12 Names and Functions of Product Parts ○Part names (2-in-1 auto switch) •D-MH2### •D-MH2##V# ○Part names (Setup Tool) Operation LED: Displays the switch operating condition. LCD display: Displays the process data display, setting mode status and error code. The upper screen is normally displayed in a single green colour, and will display in a single red colour if an error occurs.
Page 13 ■Definition and terminology Term Definition A phenomenon of repeatedly turning ON and OFF the switch output at high Chattering frequencies. A function that copies function settings (excluding settings related to output Copy function points). The setting time from when the signal of the connected 2-in-1 ASW reaches the Delay time set value to when the ON-OFF output actually begins working.
Page 14 Term Definition A difference between the ON and OFF points of the switch. A hysteresis is also referred to as hysteresis. It is a region set outside the ON width on the setup tool. Hysteresis Example: If the output point (SP1) is 688, the ON width (W_1) is 50, and the hysteresis (H_1) is 20: The hysteresis regions of switch output are 618 to 638 and 738 to 758.
Page 15 Term Definition This is the ON range of the switch output, which is set by a ± width relative to the output point set on the setup tool. ON width Example: When output point (SP1): 688, ON width (W_1): 50 The range of the process data output by the switch is 638 to 738.
Page 16 Mounting and Installation ■Installation method ○2-in-1 auto switch When mounting the 2-in-1 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 ■Wiring method ○Wiring connections ●Perform wiring connection work with the power supply turned OFF. ●Use a separate route for the product wiring. If wires and cables are routed together with power or high voltage cables, malfunction may result due to noise. ●If using a commercially available switching power supply, be sure to ground the frame ground (FG) terminal.

Page 21 2-in-1 Auto Switch Overview When power is supplied to the 2-in-1 auto switch, it outputs process data of -1000 to 1000 in response to the magnetic force of the magnet built into the cylinder/actuator. By mounting the 2-in-1 auto switch on the actuator and reading the process data value, it is possible to detect the position of the magnet.
Page 22 ○High resolution range Within the determinable range of the process data waveform above, the range where the slope of the process data against the stroke is 100 [PD/mm] or more is defined as the high resolution range. Within the high resolution range, it is possible to determine stroke differences of approximately 0.2 mm *. When using the 2-in-1 auto switch to distinguish minute dimensional differences, adjust the installation position of the 2-in-1 auto switch so that the discrimination position is within the high resolution range.
Page 23 ○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 installing the 2-in-1 auto switch so that the midpoint of the stroke coincides with the midpoint of the determinable range (approximately 0 output), it is possible to determine over the entire stroke of the actuator with a single 2-in-1 auto switch.
Page 24 ○Mounting a 2-in-1 auto switch •Actuators capable of full stroke detection With a full-stroke detectable actuator, by mounting the 2-in-1 auto switch at the recommended position, the position can be determined throughout the entire stroke. •Other actuators Adjust the 2-in-1 ASW position so that the point that needs to detect (workpiece gripping position, etc.) will be close to the centre (approximately 0 output) of the determinable range.
Page 25 Setup Tool Overview By using the 2-in-1 auto switch in combination with the setup tool, it is possible to use the 2-in-1 auto switch even without an IO-LINK master, etc. When the 2-in-1 auto switch is connected to the setup tool, the process data of the auto switch is displayed on the setup tool.
Page 26 ○2 point setting type / 3 point setting type The 2-in-1 auto switch is available as a 2-point setting type and 3-point setting type, and the usage differs depending on the type. : It is not possible to switch between the 2-point setting type and the 3-point setting type later. •2 point setting type In this type, two points, SP1 and SP2, can be set.
Page 27 •Setting range and output detection range error The 2-in-1 auto switch has a settable range, and the output range cannot be set outside that range. With a 3-point setting type, the setting ranges of SP1, SP2, and SP3 cannot overlap. If you try to set one of the above conditions, a SW output detection range error will occur and an error code (Err) will be displayed.
Page 28 ○Setting example for the 2-in-1 auto switch Finger position OUT1 OUT2 Origin position (SP1) Gripping position (SP2) Erroneous chuck (SP3) Other than the above. : There is no limit in the magnitude correlation between SP1 to SP3. -27- No.DOC1094990...
Page 29 For actuators with long strokes, it may be possible to use them by setting a delay time (refer to page 37) or using it in combination with a general purpose switch.  By setting the delay time, it is possible to set it so that no output is generated when passing through the output range at high speed. (Be sure to set according to the actual operating environment).
