GKLE3PXS2 Equivalent & Substitute Parts

Part Overview

The GKLE3PXS2 is a safety interlock switch manufactured by Honeywell Sensing and Productivity Solutions. This component is classified as obsolete, indicating it is no longer in active production. The product maintains RoHS compliance and carries an unlimited moisture sensitivity level rating (MSL 1).

Due to its obsolete status, identifying functionally equivalent substitute components is essential for system maintenance, repair, and new design implementations where interlock safety switching functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GKLE3PXS2 is based on the following critical parameters:

Functional Classification: Both the main part and substitute must serve as interlock safety switching devices.

Compliance Requirements: The substitute part must maintain RoHS compliance to meet current regulatory standards.

Moisture Sensitivity: MSL 1 rating indicates unlimited moisture tolerance, a baseline requirement for substitute selection.

Electrical Characteristics: Voltage and current ratings must be compatible with the intended application circuit.

The identified substitute, SG-B1-MA-G5 (Panasonic Industrial Automation Sales), qualifies as an equivalent based on its interlock solenoid release functionality, active product status, and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: The GKLE3PXS2 is obsolete and no longer manufactured. The SG-B1-MA-G5 represents an active, currently available alternative for interlock safety switching applications.

Compliance Status: Both parts maintain RoHS compliance. The SG-B1-MA-G5 carries ROHS3 compliance, representing the current regulatory standard. Both parts have unlimited moisture sensitivity ratings (MSL 1).

Certification Advantage: The SG-B1-MA-G5 holds multiple approval certifications (CE, cULus, TUV), providing broader regulatory acceptance across international markets compared to the obsolete GKLE3PXS2.

Electrical Specifications: The SG-B1-MA-G5 provides defined electrical parameters (2A AC/DC, 125VAC/30VDC contact rating, 24VDC supply voltage) suitable for standard industrial interlock applications.

Availability: With 954 units in current inventory, the SG-B1-MA-G5 offers reliable supply continuity for new implementations and system replacements.

Frequently Asked Questions (FAQ)

Q: Why is the GKLE3PXS2 classified as obsolete?

A: The GKLE3PXS2 has reached end-of-life status and is no longer manufactured by Honeywell. Obsolete classification indicates the manufacturer has discontinued production and support for this component.

Q: What makes SG-B1-MA-G5 a suitable substitute?

A: The SG-B1-MA-G5 functions as an interlock solenoid release switch, matching the core safety interlock switching application of the GKLE3PXS2. Both components maintain RoHS compliance and MSL 1 moisture sensitivity ratings. The substitute is currently in active production with established supply availability.

Q: Are there packaging differences between these parts?

A: The GKLE3PXS2 packaging is not specified in available documentation. The SG-B1-MA-G5 is supplied in bulk packaging. Physical dimensions and mounting configurations should be verified against application requirements during integration planning.

Q: What certifications does the SG-B1-MA-G5 hold?

A: The SG-B1-MA-G5 carries CE, cULus, and TUV certifications, providing compliance for European, North American, and international industrial applications.

Q: Can the SG-B1-MA-G5 operate in the same voltage range as the GKLE3PXS2?

A: The GKLE3PXS2 voltage specifications are not documented. The SG-B1-MA-G5 operates at 125VAC, 30VDC contact rating with 24VDC supply voltage. Application voltage compatibility must be confirmed against system requirements.

Q: What is the operating temperature range for the substitute part?

A: The SG-B1-MA-G5 operates across -25°C to 70°C, covering standard industrial temperature environments. The GKLE3PXS2 operating temperature range is not specified.

Q: Does the SG-B1-MA-G5 provide environmental protection?

A: Yes, the SG-B1-MA-G5 carries IP67 ingress protection rating, indicating dust-tight and waterproof performance suitable for harsh industrial environments.
