阀对流量的控制可以分为两种：
一种是开关控制：要么全开、要么全关，流量要么最大、要么最小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。

另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。

所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。

The product may be damaged or malfunction if it is used outside of the specification range.2) Take precautions when multiple actuators are used close together. When multiple auto switch actuators are used in close proximity, magnetic field interference may cause the switches to malfunction. Maintain a minimum actuator separation of 40 mm.3) Pay attention to the length of time that a switch is ON at an intermediate stroke position.When an auto switch is placed at an intermediate position of the stroke and a load is driven at the time the piston passes, the auto switch will operate, but if the speed is too great the operating time will be short and the load may not operate correctly. The maximum detectable piston speed is:V (mm/s) = Auto switch operating range (mm)X 1000Load operating time (ms)4) Keep wiring as short as possibleAlthough long wire length does not affect the switch function, it is recommended to keep it to 100 m or less.5) Do not use a load that generates surge voltage.Although a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if the surge is applied repeatedly. When a load such as a relay or solenoid which generates surge is directly driven, use a type of switch with built in surge protection.6) Caution for use in an interlock circuitWhen an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system by providing a mechanical protection function, or by using another switch (sensor) together with the auto switch.7) Perform periodic maintenance and confirm proper operation. Ensure sufficient clearance for maintenance activities.When designing an application, be sure to allow sufficient clearance for maintenance and inspections. 4.3 Mounting and Adjustment 1) Do not drop or bump the product.Do not drop, bump or apply excessive impact (1000 m/s 2 or more) while handling. Although the body of the switch may not appear damaged, the inside of the switch could be damaged and cause a malfunction.2) Do not carry an actuator by the auto switch lead wires.This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 3) Mount switches using the correct tightening torque.The tightening torque of the mounting screw must be 0.05 to 0.15 N•m (0.5 to 1.5 kgf•cm).If a switch is tightened beyond the tightening torque range, the mounting screw, mounting bracket or switch may be damaged.On the other hand, tightening below the tightening torque range may allow the switch to slip out of position.4) Mount a switch at the centre of the operating range.Adjust the auto switch mounting position so that the piston stops atthe centre of the operating range (the range in which the switch is ON). The mounting position shown in the catalogue indicates the optimum position at the end of stroke. If mounted at the end of the operating range (around the borderline of ON and OFF) operation may be unstable.5) The auto switch ON and OFF position operates with a hysteresis. If the hysteresis causes a problem, please consult with SMC.4.4 Auto switch mountingEach actuator has a specified mounting bracket type.Mounting depends on the actuator type and bore size. Please refer to the actuator catalogue.When an auto switch is mounted for the first time, ensure that the actuator is the type with a built-in magnet before assembly.5.1.1 Setting the Detection position Set the actuator at the stroke end.Set the Auto switch in the centre of the position where the auto switch green light is ON (optimum position).Based on dimensions A and B in the actuator catalogue, set the auto switch position. Tighten the mounting screw to the required torque.5.2 Amplifier mountingThe auto switch amplifier unit should be mounted on a DIN rail.Hold the hook on the bottom of the unit on to the DIN rail, and then push down on to the DIN rail.For removal, release the unit using a screwdriver.Mounting5.3 Wiring1) Avoid repeatedly bending or stressing lead wires.Broken lead wires can result from wiring layouts which repeatedly apply bending stress or stretching force to the lead wires. 2) Confirm proper insulation of wiring.Check that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.) Damage may occur due to excess current flow into a switch. 3) Do not route wiring with power lines or high voltage lines.Avoid parallel wiring or wiring in the same conduit with these lines. Control circuits containing auto switches may malfunction due to noise. 4) Do not allow short circuit of loads.The auto switch does not have built-in short circuit protection. Note that if a load is short circuited, the switch will be instantly damaged because of excess current flow into the switch. 5) Avoid incorrect wiring.If wiring is incorrect the switch will be damaged.5.4 Wiring diagram 5.4.1 D-M9NJ# - NPN output5.4.2 D-M9PJ# - PNP outputORIGINAL INSTRUCTIONS5.5 EnvironmentWarning•Do not use in an environment where oil, corrosive gases, chemicals, salt water or steam are present.• Do not install in a location subject to vibration or impact in excess of the product specifications.• Do not mount in a location exposed to radiant heat that would result in temperatures in excess of the product specification.• Do not use in an area where a magnetic field is generated.Auto switches can malfunction or magnets inside actuators can become demagnetized.• Do not use in an environment where the auto switch will be continually exposed to water.• Do not use in an environment with temperature cycles.• Avoid accumulation of iron waste or close contact with magnetic substances. A large amount of accumulated iron waste such as machining chips or spatter may cause the auto switch to malfunction.6.1 General MaintenanceCaution• Not following proper maintenance procedures could cause the product to malfunction and lead to equipment damage.• If handled improperly, compressed air can be dangerous.• Maintenance of pneumatic systems should be performed only by qualified personnel.• Before performing maintenance, turn off the power supply and be sure to cut off the supply pressure. Confirm that the air is released to atmosphere.• After installation and maintenance, apply operating pressure and power to the equipment and perform appropriate functional and leakage tests to make sure the equipment is installed correctly. • If any electrical connections are disturbed during maintenance, ensure they are reconnected correctly and safety checks are carried out as required to ensure continued compliance with applicable national regulations.• Do not make any modification to the product.• Do not disassemble the product, unless required by installation or maintenance instructions.• Perform the following maintenance periodically in order to prevent possible danger due to unexpected auto switch malfunction.1) Securely tighten switch mounting screws. If screws become loose or the mounting position is dislocated, re-tighten them after readjusting the mounting position.2) Confirm that there is no damage to lead wires. To prevent faulty insulation, replace switches or repair lead wires, etc., if damage is discovered.How to reset the product after power loss or forced de-energizing Regarding set up, contents of the program may be maintained by the customers application system. Be sure to confirm safety when returning operation of the actuator because it could have been stopped in an unstable condition.Refer to the catalogue or operation manual on the SMC website (URL: https:// ) for How to order information.Refer to the catalogue or operation manual on the SMC website (URL: https:// ) for outline dimensions.When detection failure occurs check the switch based on the flow chart.10.1 Limited warranty and Disclaimer/Compliance Requirements Refer to Handling Precautions for SMC Products.11 Product disposalThis product should not be disposed of as municipal waste.
