SMC SY3120-5LOU-M5-Q Solenoid Valve
1. Product Overview
The SMC SY3120-5LOU-M5-Q is a 2-position, 5-port single solenoid valve from SMC’s SY3000 series, designed for precise pneumatic control in automated systems. It features an internal pilot design, 24V DC low-power coil (0.1W with power-saving circuit), and L-type socket for easy wiring. With a 0.15–0.7 MPa operating pressure range and M5 × 0.8 ports, it controls double-acting cylinders in electronics, automotive assembly, and packaging machinery, offering rapid response (12–15 ms), reliable sealing, and maintenance-free operation. The non-locking push-type manual override enables on-site testing, while its compact zinc alloy body and flexible mounting suit dense automation setups.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Pneumatic Actuator Control | 5-port (P, A, B, R1, R2) design switches airflow to double-acting cylinders for bidirectional motion in pick-and-place or assembly tasks. |
| Manual Override | Non-locking push-type plunger allows manual actuation for debugging without power, with automatic reset to normal state. |
| Status Feedback | Built-in LED and surge protection for real-time coil status monitoring and PLC safety interlocks. |
| Low-Power Operation | 0.1W power-saving circuit reduces energy costs vs. standard 0.4W valves, ideal for high-cycle applications. |
| Rapid Airflow Switching | Internal pilot and elastic sealing enable 12–15 ms response and 10 Hz max operating frequency for fast automation cycles. |
| Flexible Mounting | Direct piping or sub-base installation; compatible with 3/5-port mix mounting for system layout flexibility. |
3. Technical Features
- Internal Pilot Design: Uses system pressure for pilot operation, eliminating external pilot lines and simplifying installation.
- Low Power Consumption: 0.1W power-saving coil cuts energy use by ~75% vs. conventional valves, reducing heat and extending coil life.
- High Durability: Die-cast zinc alloy body with elastic sealing ensures ≥50 million cycles and minimal leakage; IP65 protection for DIN/M8 connectors.
- Fast Response: 12–15 ms switching time and 10 Hz max frequency enable high-speed automation sequences.
- Versatile Porting: M5 × 0.8 female ports for P, A, B, R1, R2; supports direct or sub-base piping with standard pneumatic fittings.
- Surge & Dust Protection: Coil surge protection prevents voltage spikes; dust-resistant construction suits general industrial environments.
- Lubrication-Free: Pre-lubricated seals eliminate oiling, reducing maintenance and contamination risks.
