GX-M18A-P Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The GX-M18A-P is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales, designed for non-contact detection applications with a 4mm sensing distance. This sensor features PNP-NO output configuration in a shielded M18 threaded cylinder package. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the GX-M18A-P is determined by the following critical parameters:

• Sensor Type: Must be Inductive
• Sensing Distance: Must be 0.157" (4mm)
• Output Type: Must be PNP-NO, 3-Wire configuration
• Package / Case: Must be Cylinder, Threaded - M18
• Shielding: Must be Shielded
• Termination Style: Must be Cable Leads

The GX-318M-A-P meets all substitution criteria. While secondary parameters such as response frequency, operating temperature range, and supply voltage range differ, these variations remain within acceptable tolerance for equivalent functionality in the M18 inductive proximity sensor category.

Parameter Comparison

Engineering Selection Recommendations

The GX-318M-A-P serves as a direct substitute for the obsolete GX-M18A-P. Both sensors are manufactured by Panasonic Industrial Automation Sales and share identical core specifications for sensing distance, output configuration, and mechanical form factor.

The GX-318M-A-P is currently in active production status, ensuring availability for replacement and new system designs. The substitute part demonstrates enhanced compliance with ROHS3 standards compared to the main part's RoHS Compliant designation.

The GX-318M-A-P provides an extended supply voltage range (10V ~ 30V versus 12V ~ 24V) and broader operating temperature range (-40°C ~ 85°C versus -25°C ~ 70°C), offering greater flexibility in system integration. The reduced response frequency (600Hz versus 2kHz) and modified ingress protection ratings (IP67, IP67G, IP69K versus IP68, IP69K) should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the GX-318M-A-P directly replace the GX-M18A-P in existing installations?

A: Yes. Both sensors share identical sensing distance (4mm), output type (PNP-NO, 3-Wire), package configuration (M18 threaded cylinder), and termination style (cable leads). Mechanical and electrical interfaces are compatible.

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

A: The GX-M18A-P is obsolete, while the GX-318M-A-P is in active production. The substitute part offers extended voltage range and operating temperature specifications, along with updated RoHS3 compliance.

Q: Does the lower response frequency of the GX-318M-A-P affect compatibility?

A: Response frequency is a secondary parameter. The 600Hz response of the GX-318M-A-P remains suitable for standard inductive proximity sensing applications. Application-specific switching speed requirements should be evaluated independently.

Q: Are the ingress protection ratings equivalent?

A: Both sensors meet IP69K protection. The GX-M18A-P specifies IP68, IP69K, while the GX-318M-A-P specifies IP67, IP67G, IP69K. The highest common rating (IP69K) applies to both for harsh environment applications.

Q: What supply voltage should be used with the GX-318M-A-P?

A: The GX-318M-A-P accepts 10V ~ 30V supply voltage. Systems currently operating the GX-M18A-P at 12V ~ 24V will function within the substitute part's specified range.
