Pneumatics

Pneumatic system components are the electrical and sensing interface to pneumatic actuators, valves, and air-handling systems. Enicstra stocks pressure switches and transmitters, cylinder position sensors, flow sensors, and pneumatic-circuit accessories used across packaging, material handling, assembly, and process applications.

Inventory includes pneumatic pressure switches and transmitters from SMC, Festo, IFM, Norgren, and similar manufacturers; magnetic cylinder position sensors (reed and Hall-effect) with C, T, and slot mounting styles; pneumatic flow sensors and totalizers; valve position feedback sensors; and air-quality monitoring devices. Every part is bench-tested and ships with our 12-month functional warranty.

Pneumatic components must match the cylinder family, switching pressure, port size, and electrical output of the existing installation. Send the OEM part number with the cylinder series or pressure range when requesting a quote. Most inquiries reply within 1–2 business days.

Buying guide

Choosing Pneumatics components

Pneumatic sensor selection has more dimensions than people expect — port size, working pressure, cylinder family compatibility (for position sensors), and electrical output all need to align. A reed switch for one SMC cylinder series won't fit another series even when both are 32 mm bore.

Specifications to confirm before ordering:

Component type (pressure switch, transmitter, position sensor, flow sensor)
For pressure: working range, max overpressure, port size (G, NPT, metric)
For cylinder position sensors: cylinder manufacturer and series, mounting style (C, T, dovetail, slot)
For flow sensors: flow range, fluid (compressed air, vacuum, other gas), port size
Output signal — analog 0–10 V or 4–20 mA, switch output (PNP/NPN), digital protocol
Supply voltage (typically 24 VDC for most pneumatic sensors)
Electrical connector type (M8, M12, flying lead)
Operating temperature range

Application guidance:

End-of-stroke cylinder sensing: magnetic reed or Hall sensor matched to the cylinder series
System pressure monitoring: 0–10 bar or 0–16 bar transmitter with 4–20 mA output
Vacuum verification: vacuum switch or transmitter with appropriate range (-1 to 0 bar)
Air consumption monitoring: flow sensor with totalizer for compressed air audits
Proportional valve feedback: position sensor specific to the valve manufacturer

Cylinder position sensors are particularly format-sensitive — Festo, SMC, Numatics, and Camozzi all have different cylinder profiles, and the sensor needs to slot or clip into the specific profile. Send the cylinder model number with your sensor request.

Related categories Frequently asked questions

Can you supply SMC or Festo cylinder position sensors for older cylinder series?

Yes. Legacy SMC D-series, Festo SME/SMT series, and similar magnetic position sensors are common requests. Always match the sensor to the specific cylinder series — newer sensors often won't fit older cylinder profiles. Send the cylinder part number with the sensor request.

Reed switch versus Hall-effect — which one?

Reed switches are simpler, lower cost, and handle high switching loads but have finite mechanical contact life. Hall-effect sensors are solid-state with longer life and faster switching but require a power supply. For high-cycle applications, Hall-effect is the better choice.

What pressure range should I specify?

Choose a transmitter where your typical operating pressure is in the middle 30–70% of the sensor range — too low and resolution suffers; too high and the sensor is vulnerable to over-pressure damage. For a system running at 6 bar, a 0–10 bar transmitter is a good fit.

Are these new, surplus, or used?

Most stock is new-old-stock — unused, often in original packaging. Some legacy pneumatic sensors come from tested system removals. Each product page lists condition where known.

Do you carry pneumatic valves themselves, or just sensors?

Both. This category focuses on sensors and electrical accessories. Solenoid valves and proportional valves are listed under our Valves and Control category.
