- The upper limits of the ambient and fluid temperatures vary depending on the operating frequency. (Refer to the graph below.) If a follow-up operation is performed at a duty ratio of 50% or higher, the upper limit value may change. Please contact SMC for further details.
- Based on the JIS B 8419:2010 dynamic performance test (Coil temperature: 20°C, pressure: 0.5 MPa, at the rated voltage)
- Impact resistance: No malfunction occurred when it was tested in the axial direction and at a right angle to both the main valve and the armature in both an energized and de-energized state, once for each condition. (Values at the initial period)
Vibration resistance: No malfunction occurred in a one-sweep test between 45 and 2000 Hz. The test was performed in both an energized and de-energized state in the axial direction and at a right angle to both the main valve and the armature. (Values at the initial period) - Only applicable to the power-saving circuit specification.

Specific Product Precautions Be sure to read this before handling the products. For safety instructions and 3/4/5-port solenoid valve precautions, refer to the “Handling Precautions for SMC Products” and the “Operation Manual” on the SMC website: https://www.smcworld.com
Environment Warning
Do not use the valves in atmospheres in which corrosive gases, chemicals, sea water, water, or water vapor are present or where there is direct contact with any of these.
Manual Override Warning
The manual override is used for switching the main valve regardless of the valve’s electric signal. As the connected actuator will start operating due to this manual operation, be sure to confi rm that it is safe to do so beforehand.
- Non-locking push type
Push the manual override button all the way down.
Installation
Caution
Even if the inlet pressure is within the operating pressure range, when the piping diameter is restricted due to size reduction of the supply port (P), the fl ow will be insuffi client. In such cases, the valve will not switch completely and the cylinder may malfunction.
Surge Voltage Suppressor
- With power-saving circuit (PWM circuit built-in type, non-polar type)
The power consumption has been reduced to approx. 1/4 of the startup power by eliminating the need for electrical current for holding. (Effective after being energized for more than 5 ms when the 24 VDC rated voltage is applied)
Operating principle
The circuit shown above reduces power consumption by eliminating the need for electrical current for holding in order to save energy. Refer to the electrical power waveform shown in the graph on the right.
Residual voltage of the surge voltage suppressor
If a diode surge voltage suppressor is used, there will be a residual voltage of approx. 1 V. Pay attention to the surge voltage protection on the controller side.
M8 Connector Type
- Connector cable
· The connector cable for M8 connectors can be ordered as follows.

| 10 m | SAC-3P-10,0-PUR/M 8FR | 1694169 |
Caution Phoenix Contact products should be ordered directly from the manufacturer or from its distributors. Caution
- The M 8 connector type is IP 6 7 compliant (according to IEC 6 0 5 2 9 ) and protected against dust and water. However, it cannot be used underwater. Select an SMC connector cable (V100-49-1-) or an FA sensor type connector with M 8 threaded 3 -pin specifications conforming to Nippon Electric Control Equipment Association Standard NECA4202 (IEC 60947-5-2).
- Do not use a tool to mount the connector as this may damage it. Only tighten the connector by hand. (0.4 to 0.6 N·m)
- The application of excessive force on the cable connector will result in it no longer being able to satisfy the IP67 requirements. Please use caution and refrain from applying any force of 30 N or greater on the connector.
Failure to satisfy the IP67 requirements may result if using connectors other than those shown above or if the connector is insufficiently tightened.
Safety Instructions Be sure to read the “Handling Precautions for SMC Products” (M-E03-3) and “Operation Manual” before use.
