SMC SY5120-4DZD-01 is a SY5000 series 5 port pilot operated solenoid valve, body ported, single unit, 2 position single solenoid. It is wired for 220 V AC through a din terminal with connector, it carries an indicator light and a surge voltage suppressor, and the manual override is the push-turn locking slotted type. All ports Rc 1/8. Renda Trading Company supplies it as a genuine SMC part.
The SY family is the valve most machine builders reach for when they need a compact, fast and reliable directional valve for a double-acting cylinder. A 2 position single solenoid valve has one coil and a return spring: energise the coil and the cylinder extends, remove the signal and the spring returns the spool, so the cylinder always goes to a known state when power is lost. That behaviour is what makes it the standard choice for clamping, feeding, stopping and ejecting on production machinery.
SY5000 is the mid size and by far the most widely used, covering the majority of small and medium cylinders. Its threaded ports are Rc 1/8 and one-touch push-in fittings are available for 4 mm, 6 mm and 8 mm tube.

How to Read the Part Number SY5120-4DZD-01
SMC builds the SY part number from the series, the valve function, the coil and the port size. Once the pattern is clear, any SY valve can be read from its label.
- SY5 is the series: SY3000, SY5000, SY7000 or SY9000. This valve is SY5000.
- The next digit is the type of actuation. 1 is 2 position single solenoid, 2 is 2 position double solenoid, 3 is 3 position closed centre, 4 is 3 position exhaust centre and 5 is 3 position pressure centre. This valve is 2 position single.
- 20 is the fixed body ported single unit designation.
- 4 is the rated voltage: 220 V AC. DC codes are 5 for 24 V, 6 for 12 V, V for 6 V, S for 5 V and R for 3 V. AC codes are 1 for 100 V, 2 for 200 V, 3 for 110 V and 4 for 220 V.
- D is the electrical entry: DIN terminal with connector. G and H are grommet lead wires of 300 mm and 600 mm, L and M are the L type and M type plug connectors, D is the DIN terminal.
- Z means with light and surge voltage suppressor. Z is the usual choice because the light shows at a glance whether the coil is energised.
- D is the manual override: push-turn locking slotted type. Without this letter the valve has the plain non-locking push override.
- 01 is the port size: Rc 1/8.
The complete part number is what should be quoted when ordering, because every letter changes the article.
Typical Applications
SMC SY5120-4DZD-01 controls a double-acting pneumatic cylinder or any other air actuator that needs to be driven in two directions from a single electrical signal.
- Clamping, feeding, stopping and ejecting stations on assembly and packaging machines
- Gripper open and close on pick-and-place units and small robots
- Pushers, diverters and gates on conveyors and sorting lines
- Air blow-off and cleaning nozzles switched from the PLC
- Machine tool clamping, door and cover cylinders, indexing and locking pins
- Replacement of a failed valve on an existing machine, where the part number on the coil label has to be matched exactly
This is an AC coil version at 220 V AC, used where the machine wiring is at mains voltage and the valve is switched by a relay or contactor contact. The indicator light makes fault finding much faster: the technician can see whether the output has actually reached the coil.

Frequently Asked Questions
What is SMC SY5120-4DZD-01?
SMC SY5120-4DZD-01 is a SY5000 series 5 port pilot operated solenoid valve, body ported single unit, 2 position single solenoid. The coil is 220 V AC, the electrical entry is a din terminal with connector and the port size is Rc 1/8.
What voltage is SY5120-4DZD-01?
The coil is rated 220 V AC with an allowable fluctuation of plus or minus 10 percent. Apparent power is 2.5 VA at 220 V AC (2.6 VA with indicator light).
What does the 5 port 2 position single solenoid function mean?
Five ports means one supply port, two outlet ports to the cylinder and two exhaust ports. Two position single solenoid means the valve has one coil and a return spring, so the spool moves when the coil is energised and springs back when the signal is removed. This is what drives a double-acting cylinder out and back from one PLC output.
What is the port size of SY5120-4DZD-01?
All ports Rc 1/8. Push-in fitting versions of the same valve are available for 4 mm, 6 mm and 8 mm tube.
What is the operating pressure of SY5120-4DZD-01?
0.15 MPa to 0.7 MPa with internal pilot for a 2 position single solenoid valve. The fluid is air, lubrication is not required and the ambient and fluid temperature range is -10 °C to 50 °C without freezing.
What is the manual override on this valve?
Push-turn locking slotted type. A screwdriver turns and holds the override, which is useful when setting up a machine without power.
Can I use SY5120-4DZD-01 to replace an older SY valve?
Yes, as long as the full part number matches. Every letter in the code changes the article: the voltage, the electrical entry, the indicator light and suppressor, the manual override and the port size. Send us a photo of the label and we will confirm the exact match or the closest current equivalent.
Is SY5120-4DZD-01 a genuine SMC product?
Yes. Renda Trading Company supplies original SMC valves. The data on this page comes from the official SMC catalogue for the SY3000/5000/7000/9000 body ported valve single unit.
