FD-G40 Equivalent & Substitute Parts

Part Overview

The FD-G40 is a reflective optical sensor from Panasonic Industrial Automation Sales, part of the FX-500 series. This component features a 140mm (5.512") sensing distance and operates via cable connection with a 2-meter cable length. The FD-G40 is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FD-G40 is determined by the following critical parameters:

• Sensing Method: Reflective operation is the primary functional requirement
• Series Compatibility: FX-500 series maintains consistent electrical and mechanical interfaces
• Connection Method: Cable-based connectivity must be preserved
• Cable Length: 2-meter cable length ensures installation compatibility
• Sensing Distance: Operational range determines application suitability

The FD-42GW qualifies as a direct substitute based on identical sensing method (reflective), series (FX-500), connection method (cable), and cable length (2m). The sensing distance variance (5.9" vs 5.512") represents a minor operational difference within the reflective sensor category.

The FT-42 represents an alternative from the same series and manufacturer but operates via through-beam sensing method rather than reflective sensing, making it suitable only for applications where sensing methodology can be adapted.

Parameter Comparison

Engineering Selection Recommendations

FD-42GW is the primary substitute for FD-G40 applications. Both components maintain reflective sensing methodology, FX-500 series compatibility, cable-based connectivity, and identical 2-meter cable length. The FD-42GW carries active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment. The sensing distance difference (5.9" versus 5.512") is within typical reflective sensor operational variance and does not preclude functional equivalence.

FT-42 is applicable only when application requirements permit transition from reflective to through-beam sensing methodology. This component maintains FX-500 series compatibility, cable connectivity, and 2-meter cable length but operates on fundamentally different optical principles. Selection of FT-42 requires verification that through-beam operation is compatible with the target application environment.

Frequently Asked Questions (FAQ)

Q: Can FD-42GW directly replace FD-G40 in existing installations?

A: Yes. Both components share reflective sensing methodology, FX-500 series architecture, cable-based connection, and 2-meter cable length. The sensing distance variance (5.9" versus 5.512") represents normal operational range differences within reflective sensor specifications.

Q: What is the primary difference between FD-42GW and FT-42?

A: FD-42GW operates via reflective sensing (light reflects off target surface), while FT-42 operates via through-beam sensing (light passes between transmitter and receiver). These represent distinct optical architectures requiring different installation configurations.

Q: Why is FD-G40 listed as obsolete?

A: Obsolete status indicates the component is no longer manufactured. FD-42GW provides functional continuity with active product status and current regulatory compliance.

Q: Are all three components RoHS compliant?

A: Yes. FD-G40 carries RoHS Compliant status. FD-42GW and FT-42 carry ROHS3 Compliant status, representing current regulatory standards.

Q: Does cable length remain consistent across all options?

A: Yes. FD-G40, FD-42GW, and FT-42 all feature 78.74" (2-meter) cable length, ensuring installation compatibility.
