Festo2-242-95-0020VTUG Valve Terminal Assembly, 25-Pin Sub-D Multi-Pin Electrical Interface, 24 V DC

Product Description

What this part is

A Festo pneumatic valve terminal assembly fitted with the VAEM-L1-S-M1-25 electrical interface — the multi-pin end plate that collects every solenoid on a VTUG valve manifold onto a single 25-pin sub-D (D-sub) connector. One loom into the terminal, 24 V DC switching distributed internally to each valve. 2-242-95-0020 is the OEM assembly number; VAEM-L1-S-M1-25 is Festo’s designation for the interface itself, Festo part number 573445.

Correcting the source data

VAEM-L1-S-M1-25 is not a valve. It is the electrical interface module (M1-25 = the 25-pin multi-pin variant, catalogued by Festo as V20) and carries no air at all. The pneumatic content of this listing is the VTUG valve terminal the interface is mounted on.

Decoding the order code

VAEM — Festo electrical interface for valve terminalsL1 — interface form for the VTUG valve terminal familyS — sub-D style connectionM1 — multi-pin (parallel) wiring rather than fieldbus25 — 25 pins: up to 24 solenoid outputs plus common2-242-95-0020 — machine-builder / OEM assembly number

What these specs mean in practice

Multi-pin means each solenoid is one discrete PLC output. There is no node address, no bus terminator and no gateway firmware revision to match — the reason multi-pin terminals remain popular for retrofits and for machines with a simple output card. The cost is copper: you need a 25-way loom back to the cabinet.

Solenoid supply is 24 V DC. Nothing on this interface takes mains voltage.

The interface is family-specific. It will not convert a VTUG terminal to fieldbus, and it does not fit the older CPV or VTUB platforms.

Quantity and configuration

One assembly, new old stock. The mating 25-pin sub-D cable or loom is not included.

Installation and setup notes

Verify pin-to-valve mapping against your PLC output list before powering up — the order is set by how the terminal was originally built, not by a standard. Count the fitted valve slices and blanking plates against your circuit before ordering extra slices.

Interchange guidance

Festo 573445 is the bare interface. VAEM-L1-S-…-AP builds are the same interface family with a different connection form — related, not substitutes. 2-242-95-0040 is the sibling OEM assembly number in this family. A fieldbus VTUG terminal (CPX / CTEU) uses an entirely different end plate.
