AP-43 Pneumatic Component — Industrial Automation Spare Part

PNEUMATIC · VALVE / FITTING / ACTUATOR · QUOTE WITHIN 24H

The part number AP-43 is a short code that appears across several pneumatic-component lines used in factory automation, process control, and packaging machinery. Because “AP-43” is not unique to a single OEM, KOEED treats every AP-43 inquiry as a sourcing case and verifies the exact manufacturer, port size, and media before quoting. Engineers who work with Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE lines regularly come across AP-43 marked fittings or valves on legacy machines.

1. Key Technical Specifications & Best-Effort Decode

AP-43 is ambiguous in the open market. Before we commit to a price, KOEED confirms the OEM nameplate, port thread, and pressure class. The most common interpretations we receive in our inbox are listed below.

2. Application Scenarios — Where AP-43 Fits

AP-43 marked components appear in many of the same plants that already standardize on Fanuc CNC, Yaskawa servo, and Schneider Modicon PLCs. The most common deployment sites we see are listed below.

• Pick-and-place gantries driven by Allen-Bradley CompactLogix, where pneumatic AP-43 valves clamp and release the head
• Packaging-line air logic on Siemens S7-1200 / S7-1500 lines, using AP-43 push-in fittings to keep tubing modular
• Auto-screwdriver and riveter stations on Mitsubishi iQ-R cells — the AP-43 fitting is a common repair item
• Bottling and capping machines with Omron CP1 / CJ2 sequencing, where 5/2 AP-43 valves are still in service on 2000s-era equipment
• Fanuc Robot M-20 and ARC Mate cells that need a replacement AP-43 air-prep block after a decade of service
• Material-handling conveyors governed by Schneider Modicon M340, with photoelectric AP-43 sensors on the diverter arms
• Yaskawa MP2300 pick-and-place skids that pair AP-43 push-in fittings with the pneumatic gripper
• Vision-inspection rejects on KEYENCE CV-5000 lines, where an AP-43 sensor signals “reject” to the host PLC
• Panasonic FP-X retrofit projects in food & beverage plants, where original AP-43 fittings were installed in the late 1990s
• Maintenance / spares stock for any of the above — the AP-43 is a high-consumable, low-cost item that we recommend keeping 2–4 of on the shelf

If your AP-43 sits on a machine that runs a different controller, send the system architecture (PLC brand, I/O count, valve-manifold type) along with the nameplate photo and we will cross-reference it in the same Create a Quote ticket.

3. Integration & Wiring Notes

The right wiring / tubing strategy depends on which AP-43 family the unit belongs to. The notes below cover the four interpretations.

• Push-in fitting (Parker / generic) — no electrical wiring. Cut the tube square, push it in until the collet clicks, and pull back gently to seat. For 1/4” NPT ports, wrap with PTFE tape (2–3 turns, clockwise) and torque to 8–10 Nm.
• 5/2 solenoid valve (Asco Numatics) — coil voltage must match the PLC output module. Common voltages: 24 VDC (sink/source from Siemens / Mitsubishi / Omron transistor outputs) and 110/230 VAC. Use a MOV or flyback diode on DC coils. Pilot air supply 2–8 bar.
• Pneumatic actuator — double-acting cylinders need 5/3 closed-center valves; single-acting use 3/2. Always check the AP-43 actuator stroke against the original spec sheet to avoid over-travel.
• Photoelectric sensor (Autronics AP-43) — three-wire PNP/NPN, 10–30 VDC. Brown = V+, Blue = 0 V, Black = signal. Wire the black lead into a 24 VDC digital input on the host PLC. Shielded cable is recommended when running parallel to VFD power cables near Yaskawa or Schneider drives.

When the AP-43 is tied into a controller from any of the nine brands KOEED covers (Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE), share the I/O assignment (rack/slot, terminal number, address) and we will return a side-by-side wiring diagram alongside the quote.

5. Procurement, Warranty & Lead Time

Because AP-43 is a short code with multiple OEM interpretations, the procurement flow at KOEED is designed to remove the guesswork before any money changes hands.

• Confirm the OEM — send a nameplate photo (or a clear shot of the body marking) to Moritta@KOEED.COM. We decode the AP-43 into Parker, Asco, Bermad, Autronics, or another line and reply with the exact cross-reference within one business day.
• Request a quote — once the OEM is fixed, fill in the Create a Quote form with quantity and target lead time, or simply reply on the same email thread. We do not lock customers into minimum-order quantities for short codes like AP-43.
• Lead time — common AP-43 fittings and 5/2 valves are typically dispatched from our Hong Kong / Shenzhen warehouse within 3–5 business days after payment. Obsolete or AP-43 sensor variants that are no longer produced may take 2–4 weeks while we source from our China Sourcing Company network. We confirm the exact lead time inside the same quote email.
• Warranty & authenticity — every AP-43 ships with a KOEED inspection note covering visual check, dimensional check, and (where applicable) electrical / pressure test on a 100% basis. Worldwide shipping via DHL, FedEx or UPS. See Shipping Policy and Return Policy for full terms.
• Bulk / BOM pricing — if AP-43 is one line on a larger instrument list, send the whole BOM to Moritta@KOEED.COM and we will quote the entire bill of materials from the same nine-brand catalog (Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, KEYENCE).

Engineers who need a faster first pass on the AP-43 can also try the KOEED AI Diagnostic Tool for a 24/7 preliminary read, then send the same part list to our team for stock and price confirmation.
