DSNU-20-100-PPV-A

Product information

Product Overview

The DSNU is Festo’s round-body cylinder based on ISO 6432, with self-adjusting end-position cushioning and an extensive accessory range. Because the barrel is round and the mounting is carried on the end caps, the DSNU is used where the barrel does not need the sensor slots of a profile cylinder, or where the round form suits the machine frame. Festo’s positioning highlights the wide range of variants, the good running performance and long service life, and the self-adjusting cushioning that saves commissioning time.

This page covers DSNU-20-100-PPV-A — Festo type code DSNU-20-100-PPV-A, order number 19239. Everything below is taken from Festo’s own product data for this order number: the technical values, the category path, the GTIN and the lifecycle notice are all reproduced from the manufacturer’s page rather than paraphrased, so you can check them against Festo’s documentation before you buy.

The order number and the type code both have to match. A single character in the type code can change the valve function, the cushioning or the connection, and it always changes the order number.

Lifecycle and Availability

Festo’s product page for this order number does not currently carry a discontinuation or successor notice, so we list it as a standard catalogue item. Availability is always confirmed against Festo’s stock at the time you order — we do not keep a stock figure on this page because it would be out of date the day it was written.

Official Documentation

Every figure on this page comes from Festo. Use the manufacturer’s own documents to verify it:

• Festo official product page — DSNU-20-100-PPV-A — the source of the technical values and the lifecycle notice above.
• Festo official series catalogue (PDF) — Festo’s own catalogue for this series, including the type code breakdown and the ordering data for every variant.

Ordering This Part

Before we quote, please confirm:

• the complete Festo type code, exactly as it appears on the drawing or the nameplate — not just the series name;
• the order number if you have it, so we can cross-check the code against Festo’s catalogue;
• the quantity and the delivery address;
• for cylinders, the stroke and the mounting style, because both are fields in the order code;
• for valves and sensors, the electrical connection and the voltage, because these are fields in the order code.

Send us a photograph of the nameplate if the code is hard to read — that is usually the fastest way to avoid shipping the wrong variant.

Frequently Asked Questions

Is the DSNU interchangeable with an ISO 6432 cylinder from another maker?
It is based on ISO 6432, so the key mounting and port dimensions follow the standard. Even so, check the order code: the cushioning and position-sensing fields change the part number, and accessories are usually family-specific.

What is the difference between DSNU and DSBC/DNC?
The DSNU is a round-body cylinder based on ISO 6432; the DNC and DSBC are profile cylinders to ISO 15552. They are different standards with different mounting patterns and different port threads — do not substitute one for the other without checking the drawing.

Which DSNU variants appear in our catalogue?
We list both a standard DSNU-32-50-P-A with elastic cushioning plates and a DSNU-20-100-PPV-A with adjustable pneumatic cushioning and a magnet piston for position sensing. Send us your code and we will confirm the exact variant.

Do you supply the mounting accessories with the cylinder?
Yes — foot mounting, flange mounting, clevis, rod eyes and the rest of the ISO 6432 accessory range can be quoted together with the cylinder.
