GS-8S Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The GS-8S is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales, designed for non-contact detection applications requiring a 2mm sensing distance. This cylindrical sensor features stainless steel construction, cable lead termination, and IP67 ingress protection suitable for industrial environments.

The GS-8S is classified as obsolete. Locating equivalent or substitute components is necessary to maintain system functionality and ensure continued availability for replacement or new installations where this sensor specification is required.

Key Parameters

Substitute Part Grouping Explanation

The GH-8SE is identified as a substitute for the GS-8S based on the following alignment criteria:

Common Parameters:

• Manufacturer: Panasonic Industrial Automation Sales
• Sensor Type: Inductive
• Shielding: Unshielded
• Material - Body: Stainless Steel
• Termination Style: Cable Leads
• Operating Temperature: -10°C ~ 60°C
• Ingress Protection: IP67
• Package / Case: Cylinder

Substitution Basis: The GH-8SE maintains the core inductive sensing technology, environmental protection rating, and mechanical form factor of the GS-8S. Both sensors are cylindrical inductive proximity sensors with identical operating temperature ranges and IP67 protection. The primary difference is the sensing distance specification: the GH-8SE provides 0.157" (4mm) sensing distance compared to the GS-8S 0.079" (2mm), and includes integrated NPN-NC/NO output with 3-wire configuration and 12V ~ 24V supply voltage, eliminating the external amplifier requirement of the GS-8S.

Parameter Comparison

Engineering Selection Recommendations

The GH-8SE is an active product with current manufacturing status and ROHS3 compliance, providing a viable path forward from the obsolete GS-8S. Both sensors maintain identical environmental specifications (IP67, -10°C ~ 60°C operating range) and stainless steel construction, ensuring compatibility in harsh industrial environments.

Selection of the GH-8SE requires evaluation of the increased sensing distance (4mm versus 2mm) and the integrated output stage. The GH-8SE eliminates the external amplifier requirement of the GS-8S through its built-in NPN-NC/NO output configuration with 12V ~ 24V supply voltage. Applications requiring the specific 2mm sensing distance of the GS-8S may require alternative sensor models outside this substitute grouping.

Frequently Asked Questions (FAQ)

Q: Can the GH-8SE directly replace the GS-8S in all applications?

A: Direct replacement depends on sensing distance requirements. The GH-8SE provides 4mm sensing distance versus the GS-8S 2mm specification. If your application requires detection at 2mm distance, the GH-8SE may not be suitable. Both sensors share identical environmental protection (IP67), operating temperature range (-10°C ~ 60°C), and cylindrical stainless steel form factor.

Q: What is the primary difference in output configuration?

A: The GS-8S requires an external amplifier for signal processing, while the GH-8SE includes integrated NPN-NC/NO output with 3-wire configuration and 12V ~ 24V supply voltage. This eliminates the need for external amplification circuitry when using the GH-8SE.

Q: Are both sensors RoHS compliant?

A: Yes. The GS-8S is RoHS Compliant, and the GH-8SE is ROHS3 Compliant. Both meet current environmental compliance standards.

Q: What packaging is available for each sensor?

A: The GS-8S is supplied in standard packaging, while the GH-8SE is supplied in Box packaging. Both maintain identical cylindrical sensor form factors.

Q: Why is the GS-8S listed as obsolete?

A: The GS-8S has been discontinued by the manufacturer. The GH-8SE represents the active product line continuation from Panasonic Industrial Automation Sales for inductive proximity sensing in this form factor and environmental class.
