Lucas Schaevitz A263-0118 — Low-G DC Accelerometer (±1G to ±3G)

Lucas Schaevitz (Measurement Specialties / TE Connectivity) · DC Output · Stud Mount · In stock

The Lucas Schaevitz A263-0118 is a low-G DC output accelerometer from the legacy Lucas Schaevitz L-Series (now carried under Measurement Specialties / TE Connectivity). User-selectable ranges of ±1G, ±2G and ±3G make it a fit for tilt / inclination, low-frequency vibration, and structural health monitoring where a clean 0–5 V DC signal is needed straight into a PLC, data logger or SCADA terminal — no charge amplifier required.

Engineers retrofitting the A263-0118 into existing racks of Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE controllers — and matching the form factor of older Schaevitz L-Series studs — will find the pin-out and 5–30 V DC excitation easy to land on a standard analog input card.

2. Application Scenarios — Where the A263-0118 Fits

The A263-0118 is a DC-coupled low-G accelerometer, so its strongest use cases are slow-changing acceleration and steady-state tilt rather than high-frequency shock. Typical installations include:

• Tilt & inclination sensing on AGV chassis, scissor-lift platforms, and overhead crane booms feeding a Siemens SIMATIC or Allen-Bradley CompactLogix analog input.
• Low-frequency vibration monitoring on rotating machinery (fans, mixers, conveyor drives) where a 0–5 V output drops directly into a 4–20 mA / V card on Mitsubishi MELSEC or Schneider Modicon.
• Seismic & structural health monitoring on bridges, building floors, and telecom towers for long-term drift and tilt trending.
• Ship roll / pitch and offshore platform motion on marine monitoring panels — the DC response and sealed housing suit the slow-roll profile.
• Vehicle dynamics & ride-height testing on automotive proving-ground rigs and off-road equipment (wheel loader, dump truck, telehandler) tilt safety interlocks.
• Robotics stability & end-effector gravity compensation when paired with Fanuc, Yaskawa or KEYENCE motion controllers.
• Renewable / wind turbine tower lean and solar tracker angle feedback on Omron or Panasonic FP based monitoring PLCs.

3. Integration & Wiring Notes

Because the A263-0118 produces a 0–5 V DC output that is ratiometric to the excitation voltage, power supply quality matters. Feed it from a regulated 12 V or 24 V rail and protect the analog input with proper shielding — not a noisy DC bus shared with VFDs.

On the controller side, scale engineering units in the PLC: 0 V = −range, 2.5 V = 0G, 5 V = +range. For float conversions and endianness, use the PLC Hex to Float Converter, and for raw 4–20 mA / 0–10 V scaling, the PLC Analog Calculator saves time at commissioning. Diagnose noisy readings or unknown part numbers with the KOEED AI Diagnostic Tool.

4. Installation & Commissioning Tips

• Mounting surface must be flat and clean. Use the supplied stud (M5 or 10-32) torqued to spec — an uneven base will bias the DC zero and show up as a permanent tilt offset.
• Align the sensing axis with the direction of interest. The A263-0118 is single-axis — confirm the arrow on the housing matches the measurement vector before energising.
• Route the cable away from VFD outputs and motor leads. A 100 mm segregation from 480 V three-phase cabling is a good rule of thumb for 0–5 V DC signals.
• Allow a 5-minute warm-up before capturing the zero-G offset, then store the offset in the PLC for software null.
• Use a shielded, twisted-pair cable in conduit where possible; ground the shield at the PLC end only to avoid ground loops.
• Confirm the selected range (±1G / ±2G / ±3G) on the first power-up by reading the no-load output; a mid-scale 2.5 V at rest is the healthy baseline.
• Document the calibration date and range in the PLC tag so the next maintenance window can re-verify against the PLC error-code database if a downstream channel faults.

5. Procurement, Warranty & Lead Time

KOEED is a multi-brand industrial-automation sourcing company, not an OEM subsidiary. We source the Lucas Schaevitz A263-0118 through vetted channels so customers can keep a long-running tilt / structural-health loop alive even after the original brand was absorbed by Measurement Specialties and then TE Connectivity. Send the full BOM and we will quote the lot in one email.

• Quote turnaround: within 24 hours on business days — single part or full BOM.
• Shipping: worldwide via DHL / FedEx / UPS from our Shenzhen & Hong Kong dual base.
• Warranty: tested before shipment; contact us for the latest terms.
• Cross-reference: send a photo of the nameplate or a legacy part number and we will suggest a TE / Measurement Specialties equivalent.
