FD-61G Equivalent & Substitute Parts

Part Overview

The FD-61G is a reflective optical sensor manufactured by Panasonic Industrial Automation Sales, part of the FX-500 series. This sensor features a 420mm (16.535") sensing distance and operates with a cable connection method, offering IP67 ingress protection. The FD-61G is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the FD-61G is based on the following critical parameters that determine functional compatibility:

• Sensing Method: Reflective operation must be maintained
• Series Compatibility: FX-500 series maintains consistent electrical and mechanical interfaces
• Connection Method: Cable-based connection required
• Cable Length: 2m standard length
• Sensing Distance Range: Acceptable variance within optical sensor specifications

The FD-61 (base model without the "G" designation) qualifies as a substitute based on these parameters. While the FD-61 offers an increased sensing distance of 450mm (17.717") compared to the FD-61G's 420mm, both sensors operate within the same FX-500 series architecture and share identical connection methodology and cable specifications.

Parameter Comparison

Engineering Selection Recommendations

The FD-61 serves as the active production equivalent for the obsolete FD-61G. Both components maintain identical mechanical and electrical interfaces within the FX-500 series. The FD-61 provides enhanced sensing distance capability (450mm versus 420mm), which represents a functional improvement for applications requiring extended detection range.

From a compliance perspective, the FD-61 meets current RoHS3 requirements, whereas the FD-61G meets legacy RoHS compliance standards. Both components carry MSL Level 1 ratings, indicating unlimited moisture sensitivity protection.

For new designs or system replacements, the FD-61 is the appropriate selection due to its active product status and current regulatory compliance. For legacy system maintenance where sensing distance is a critical constraint, the increased range of the FD-61 may require application-level validation.

Frequently Asked Questions (FAQ)

Q: Can the FD-61 directly replace the FD-61G in existing installations?

A: Yes. Both sensors share identical connection methodology, cable specifications, and series architecture. The primary difference is sensing distance: FD-61 provides 450mm range versus FD-61G's 420mm range. Applications with spatial constraints should account for this extended detection capability.

Q: What is the significance of the product status difference?

A: The FD-61G is classified as obsolete, indicating discontinued manufacturing and limited availability. The FD-61 maintains active production status, ensuring supply chain continuity and access to current manufacturing batches.

Q: Are there compliance differences between these parts?

A: Both components are RoHS compliant. The FD-61G meets RoHS standards, while the FD-61 meets the more recent ROHS3 specification. Both carry identical MSL Level 1 ratings for moisture sensitivity.

Q: Does the increased sensing distance of the FD-61 affect system performance?

A: The FD-61's 450mm sensing distance represents an extension of the FD-61G's 420mm capability. Applications designed for the shorter range will function with the FD-61; however, systems with precise distance-dependent logic should be reviewed for compatibility.

Q: What packaging options are available?

A: The FD-61 is supplied in Box packaging. Standard cable length for both components is 2m (78.74").
