WLG2-TH-N OMR Equivalent & Substitute Parts

Part Overview

The WLG2-TH-N OMR is a limit switch manufactured by Omron Automation and Safety. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing system maintenance and new designs. Limit switches serve as critical control components in industrial automation, machinery, and safety systems where position detection and circuit switching are required.

Substitute Part Grouping Explanation

Substitution for the WLG2-TH-N OMR is determined by the following criteria derived from the WL series family:

Primary Substitutes:

• WLG2-TH-F: Active status, same base product number (WLG2-TH), identical series designation, matching MSL rating, and equivalent regulatory classifications (ECCN, HTSUS)
• WL01G2-TH-F: Active status, same series designation, matching MSL rating, and equivalent regulatory classifications

Both substitute parts maintain compatibility through shared mechanical mounting characteristics (Chassis Mount, Screw Terminal), identical ingress protection rating (IP67), and equivalent operating environmental specifications. The substitutes are differentiated by current and voltage ratings, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

WLG2-TH-F is the primary substitute for WLG2-TH-N OMR. This part shares the identical base product number (WLG2-TH), confirming design continuity within the WL series. The WLG2-TH-F maintains active product status, RoHS compliance, and equivalent regulatory classifications (ECCN EAR99, HTSUS 8536.50.9055). Current and voltage ratings are higher (5A AC, 400mA DC, 125V AC/DC) compared to the WL01G2-TH-F variant, making it suitable for applications requiring greater power handling capacity.

WL01G2-TH-F serves as an alternative substitute for lower-power applications. This part is also active, RoHS compliant, and maintains equivalent regulatory status. The reduced current rating (100mA AC/DC) and lower DC voltage rating (30V) make this option appropriate for signal-level switching and lower-power control circuits.

Both substitutes are qualified for the same operating temperature range (5°C ~ 120°C), provide identical mechanical life specifications (10,000,000 cycles), and maintain the same ingress protection rating (IP67). Selection between WLG2-TH-F and WL01G2-TH-F depends on the electrical load requirements of the specific application.

Frequently Asked Questions (FAQ)

Q: Why is the WLG2-TH-N OMR classified as obsolete? A: The WLG2-TH-N OMR has reached end-of-life status within Omron's product portfolio. Active equivalents within the WL series are available to support continued system operation and new designs.

Q: What is the primary difference between WLG2-TH-F and WL01G2-TH-F? A: The primary difference is current and voltage rating capacity. WLG2-TH-F is rated for 5A AC and 400mA DC at 125V AC/DC, while WL01G2-TH-F is rated for 100mA AC/DC at 125V AC and 30V DC. Select based on your circuit's power requirements.

Q: Are the substitute parts mechanically compatible with the original WLG2-TH-N OMR? A: Both substitute parts share identical mounting type (Chassis Mount) and termination style (Screw Terminal) specifications. Physical verification against your specific installation is required to confirm fit within existing mechanical assemblies.

Q: Do the substitute parts meet the same environmental specifications? A: Yes. Both WLG2-TH-F and WL01G2-TH-F maintain the same operating temperature range (5°C ~ 120°C), ingress protection rating (IP67), and moisture sensitivity level (MSL 1 - Unlimited) as the original part.

Q: Are the substitute parts RoHS compliant? A: Yes. Both WLG2-TH-F and WL01G2-TH-F are RoHS compliant. The original WLG2-TH-N OMR RoHS status was not specified in available documentation.

Q: What electrical life can be expected from the substitute parts? A: Both substitute parts are rated for 750,000 electrical cycles, with mechanical life rated at 10,000,000 cycles under specified operating conditions.
