LAM Research 796-901039-002 Spare for IR-SENS V Automation: Precision Spare Parts Replacement for Semiconductor Process Control

The LAM Research 796-901039-002 is an original infrared sensor module (IR-SENS V) designed for use in LAM Research semiconductor processing equipment and advanced automation control systems. Carrying the full SKU reference IR-SENS V 14036-PE44-AGN1 LAM 796-901039-002 1075326, this module serves as a critical sensing component in process chambers, endpoint detection circuits, and thermal monitoring subsystems. For maintenance engineers managing aging LAM Research platforms, sourcing a verified original spare is the fastest path to restoring uptime and avoiding costly process deviations.

At SMARTNEXMSK, every unit undergoes pre-shipment functional inspection and is dispatched with a 12-month warranty, ensuring your maintenance team receives a field-ready replacement with full traceability.

Maintenance Planning for Continuous Operation

When replacing the LAM Research 796-901039-002 IR-SENS V module during scheduled or emergency maintenance, a thorough inspection of the surrounding control circuit is essential to prevent repeat failures and ensure system stability. Maintenance engineers should treat this replacement as an opportunity to audit the full sensing and signal chain.

Begin by verifying the 24 VDC or 5 VDC power supply rail feeding the sensor module — voltage ripple or transient spikes are a leading cause of premature sensor degradation in semiconductor equipment. Check the associated power distribution module and any inline fuse or circuit protection components for signs of thermal stress or intermittent contact.

Next, inspect the signal conditioning board or analog input module that receives the IR-SENS V output. Verify that the input impedance and signal range remain within the module’s specified output parameters. If the system uses a signal isolator between the sensor and the PLC or DCS analog input card, confirm isolation integrity — degraded isolators are a common hidden fault in aging semiconductor control cabinets.

Review the terminal block connections on the sensor wiring harness. Loose or oxidized terminals at the I/O junction are a frequent source of intermittent faults that mimic sensor failure. Torque all terminals to specification and apply contact protection where appropriate.

For systems using a LAM Research process controller or embedded PLC rack, confirm that the corresponding analog input channel on the I/O module is reading within calibrated range after the new sensor is installed. If the system includes a communication module (e.g., EtherNet/IP or DeviceNet interface card) linking the sensor data to a supervisory SCADA or MES layer, verify that the data tag mapping remains intact post-replacement.

Where the IR-SENS V is part of an endpoint detection subsystem, also inspect the associated optical window or viewport assembly, any fiber optic coupling components, and the photodetector reference module used for baseline calibration. Contamination or misalignment in these adjacent components will cause the new sensor to report erroneous readings even if the module itself is fully functional.

Finally, if the equipment cabinet houses additional relay output modules or solid-state relay (SSR) banks that act on the sensor signal for interlock or alarm functions, test their switching response after sensor replacement to confirm the full protective chain is operational. Documenting this inspection in your CMMS as part of the work order closure ensures traceability for future audits and spare parts planning.

Site Replacement Workflow

Step 1 — Isolation & Lockout: Follow your site LOTO procedure. De-energize the sensor circuit and confirm zero-energy state at the terminal block before disconnecting the 796-901039-002 module.

Step 2 — Documentation: Photograph the existing wiring configuration and record the current sensor output value from the HMI or SCADA historian before removal. This baseline is critical for post-installation verification.

Step 3 — Module Removal: Disconnect the signal and power connectors. Remove the module from its mounting bracket or DIN rail seat. Note the orientation and any keying features specific to the IR-SENS V form factor.

Step 4 — New Module Installation: Install the replacement LAM Research 796-901039-002 in the same orientation. Reconnect all signal and power leads per the documented wiring photograph. Torque terminal connections to specification.

Step 5 — Power-Up & Calibration Check: Re-energize the circuit. Observe the sensor output on the HMI or analog input display. Compare against the pre-removal baseline. If the system requires a zero/span calibration procedure, execute it per the LAM Research maintenance manual before returning the equipment to production.

Step 6 — Functional Verification: Run a short process cycle or simulation to confirm the sensor is responding correctly across the expected measurement range. Verify that all downstream interlocks and alarms are functioning as designed.

Step 7 — CMMS Update: Log the replacement in your maintenance management system with the new module’s serial number, installation date, and next scheduled inspection interval. Update your spare parts inventory to trigger reorder of a replacement unit for your critical spares buffer.

Spare Parts Support FAQ

Q1: Is the LAM Research 796-901039-002 an original OEM part or an aftermarket replacement?
The 796-901039-002 supplied by SMARTNEXMSK is an original LAM Research OEM component, not an aftermarket or third-party substitute. Each unit is sourced through verified supply channels and undergoes pre-shipment functional testing to confirm it meets OEM specifications before dispatch.

Q2: How do I confirm compatibility with my existing IR-SENS V / 14036-PE44-AGN1 system before ordering?
Compatibility is confirmed by matching the full SKU string: IR-SENS V 14036-PE44-AGN1 LAM 796-901039-002 1075326. If you have the equipment’s BOM or maintenance manual, cross-reference the part number against the sensor assembly drawing. Our technical team at [email protected] can assist with compatibility verification if you provide your equipment model and revision level.

Q3: What does the 12-month warranty cover, and what is the claims process?
The 12-month warranty covers manufacturing defects and functional failure under normal operating conditions from the date of shipment. It does not cover damage resulting from incorrect installation, overvoltage, or physical mishandling. To initiate a warranty claim, contact [email protected] with your order number, a description of the fault, and any available diagnostic data. Replacement or repair will be arranged within the warranty period.

Q4: Can SMARTNEXMSK support long-term or blanket spare parts orders for this module?
Yes. For facilities managing multiple LAM Research systems or planning multi-year maintenance contracts, SMARTNEXMSK offers long-term supply agreements and priority stock reservation for critical spare parts including the 796-901039-002. Contact our team to discuss volume pricing, lead time commitments, and consignment stocking options tailored to your planned maintenance schedule.
