GS-8S-C8 Equivalent & Substitute Parts

Part Overview

The GS-8S-C8 is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales, designed for non-contact object detection in industrial applications. This cylindrical sensor features a 2mm sensing distance, stainless steel construction, and IP67 ingress protection rating. The sensor operates with cable lead termination and requires an external amplifier for signal output.

The GS-8S-C8 is classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is necessary for system maintenance, replacement, and new design implementations where this sensor type is specified.

Key Parameters

Substitute Part Grouping Explanation

The GH-8SE is identified as a substitute for the GS-8S-C8 based on the following substitution criteria:

Common Parameters (Substitution Basis):

• Sensor Type: Both are inductive proximity sensors
• Material - Body: Both use stainless steel construction
• Termination Style: Both feature cable lead termination
• Operating Temperature Range: Both operate within -10°C ~ 60°C
• Ingress Protection: Both maintain IP67 rating
• Package / Case: Both are cylindrical sensors
• Manufacturer: Both are Panasonic Industrial Automation Sales products

Differing Parameters (Design Evolution):

• Sensing Distance: GH-8SE provides 0.157" (4mm) versus GS-8S-C8's 0.079" (2mm)
• Output Type: GH-8SE features integrated NPN-NC/NO 3-wire output versus GS-8S-C8's amplifier requirement
• Supply Voltage: GH-8SE operates on 12V ~ 24V versus GS-8S-C8's unspecified supply
• Response Frequency: GH-8SE specifies 3.3kHz response capability
• Product Status: GH-8SE is active; GS-8S-C8 is obsolete

Parameter Comparison

Engineering Selection Recommendations

The GH-8SE is an active substitute for the obsolete GS-8S-C8. Both sensors share core inductive proximity detection architecture, stainless steel construction, and identical environmental operating parameters. The GH-8SE maintains RoHS3 compliance, exceeding the RoHS compliance level of the GS-8S-C8.

Selection of the GH-8SE requires evaluation of the following design differences:

Sensing Distance Variance: The GH-8SE provides a 4mm sensing distance compared to the GS-8S-C8's 2mm distance. Applications requiring detection at shorter distances must account for this increased sensing range.

Output Configuration: The GH-8SE integrates NPN-NC/NO 3-wire output capability, eliminating the external amplifier requirement of the GS-8S-C8. This represents a functional enhancement reducing system complexity and component count.

Supply Voltage Specification: The GH-8SE operates on 12V ~ 24V supply voltage. System integration must confirm compatibility with available power supplies.

For applications where the 2mm sensing distance of the GS-8S-C8 is critical and cannot be accommodated by the 4mm GH-8SE specification, alternative inductive proximity sensors within the Panasonic GS or GH series should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the GH-8SE directly replace the GS-8S-C8 in existing installations?

A: Direct replacement requires verification of two factors: (1) the application's sensing distance requirement must accommodate the GH-8SE's 4mm range versus the GS-8S-C8's 2mm range, and (2) the system's power supply must provide 12V ~ 24V for the GH-8SE's integrated output circuit.

Q: What is the primary functional difference between these sensors?

A: The GS-8S-C8 requires an external amplifier for signal conditioning, while the GH-8SE incorporates integrated NPN-NC/NO 3-wire output. This represents a design evolution toward simplified system integration.

Q: Are both sensors suitable for IP67-rated applications?

A: Yes. Both the GS-8S-C8 and GH-8SE maintain IP67 ingress protection rating and stainless steel construction, qualifying them for sealed and washdown environments.

Q: Does the GH-8SE's increased sensing distance affect detection accuracy?

A: Sensing distance and detection accuracy are distinct parameters. The GH-8SE's 4mm sensing distance is a design specification. Applications must confirm that target objects can be positioned within this detection range.

Q: Are there compliance differences between these sensors?

A: The GH-8SE carries ROHS3 compliance, while the GS-8S-C8 carries RoHS compliance. Both meet regulatory requirements for their respective product generations. The GH-8SE represents current compliance standards.

Q: What packaging formats are available for these sensors?

A: The GS-8S-C8 is supplied with cable lead termination. The GH-8SE is supplied in box packaging with cable lead termination. Both maintain cylindrical form factor.
