Although a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if a surge is applied repeatedly. When directly driving a load that generates surge, such as a relay or solenoid valve, use a switch with a built-in surge absorbing element. 8.

It is again necessary to connect a contact protection box in order to extend its life. Please contact SMC in this case. If driving a load such as a relay that generates a surge voltage, use a switch with a built-in contact protection circuit or use a contact protection box.

Do not use a screwdriver with a large grip or with a tip that does not fit into the trimmer groove.

Operate the piston within a range such that collision damage will not occur at the end of the stroke. When a cylinder is used in a clamping mechanism, there is a danger of work pieces dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc.

as a stopper, select a model with a stroke of 50mm or less.

Do not use a load that generates surge voltage. If driving a load such as a relay that generates a surge voltage, use a switch with a built-in contact protection circuit or use a contact protection box.

Operating principle A + A' A' A Piston seal A' A' R H R H When the piston is retracting, air is exhausted through both A and A' until piston seal H passes air passage A. After piston seal H has passed air passage A, air is exhausted only through A'. The section marked with slanted lines becomes a cushion chamber, and an air cushion effect is achieved.

When a load, such as a relay or solenoid valve, which generates surge is directly driven, use a type of switch with a built-in surge absorbing element. 8.

When excessive impact (300m/s2 or more) is applied to a reed auto switch during operation, the contacts may malfunction and generate or cut off a signal momentarily (1ms or less). Please consult with SMC if a solid state auto switch can be used according to the environment. Do not use in an area where surges are generated.

Operate the piston within a range such that collision damage will not occur at the stroke end. 5. Consider a possible drop in operating pressure due to a power outage, etc. When a cylinder is used in a clamping mechanism, there is a danger of work pieces dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc.

When excessive impact (300m/s2 or more) is applied to a reed switch during operation, the contact point will malfunction and generate or cut off a signal momentarily (1ms or less). Consult SMC regarding the need to use a solid state switch depending upon the environment. 7. Do not use in an area where surges are generated.
