N510054844AA Panasonic SMC Solenoid Valve VQ111U-5LO-X480 NPM

Product Overview

The SMC valve fitted to a Panasonic NPM placement head is a small component with a large job: it switches the air the head uses to pick, place and release components. This replacement valve is built to the same configuration as the unit that comes on the machine, so a maintenance team can change a failed valve without reworking the air circuit around it.

It is a pneumatic solenoid valve rather than a general-purpose industrial valve, which is why the machine model and the position on the head matter as much as the valve family. Most orders come from SMT maintenance technicians, equipment engineers and the people who order spares for a running Panasonic line — usually a unit or two to cover a fault, then a small quantity to hold as line stock.

Key Features

• SMC valve platform — The valve is built on the SMC body used on Panasonic placement equipment, so the mounting points and port pattern line up with the original without adapters.
• NPM configuration — It is supplied in the configuration the NPM platform uses, keeping switching behaviour consistent with the rest of the head instead of introducing a generic air valve.
• Changeable at the head — The valve can be swapped during a planned maintenance window, so a fault does not force a head rebuild or a long removal.
• Built for continuous production — This is a valve that cycles with the head through a full shift, so it is intended for the duty of a running placement line rather than occasional use.

Specifications

Model Reference & Replacement

N510054844AA identifies this variant of the valve. The quickest way to be sure of what is on the machine is to read the number on the valve body itself. Solenoid valve manufacturers build families of valves that share a body shape and port layout but are set up for different platforms, so the printed code is what actually separates one variant from another.

If the label has worn away, send a photo of the valve in place on the head together with the machine model, and the variant can normally be confirmed from that. Keeping the number in the maintenance record also pays off later: the next replacement becomes a repeat order rather than a fresh search.

Installation & Commissioning

1. Isolate the air supply to the head and let residual pressure bleed off before opening the valve block.
2. Note how the old valve sits and photograph the connections so the replacement goes back in the same orientation.
3. Release the retaining screws, lift the valve clear and keep the old seals with it for comparison.
4. Inspect the seals, port faces and manifold seating — a hardened or scored seal will leak again even with a fresh valve fitted.
5. Seat the replacement squarely, then tighten the screws in stages instead of fully tightening one before the others.
6. Restore air and cycle the head manually, checking for leaks and for pick-up that responds slowly, before the machine returns to production.

Applications on the Line

• Planned head maintenance — Changed during a scheduled stop in the same access window as nozzles and filters, so the head goes back into production with a refreshed air path.
• Breakdown recovery — When a head on a Panasonic pick and place machine stops picking cleanly or an air leak appears mid-shift, a valve already on site keeps the repair local instead of waiting on a delivery.
• Service companies on customer sites — Teams maintaining Panasonic equipment for several plants fit this valve during call-outs and carry the common variants so a job is not split over two visits.
• Refurbishment work — Dealers and refurbishers rebuilding used NPM heads fit a fresh solenoid valve before the machine goes back into service or on to a new owner.
• Process consistency — A valve that switches cleanly keeps pick-up timing steady across a long run, which matters when the same program runs for hours.
