GKLB2A2S2 Equivalent & Substitute Parts

Part Overview

The GKLB2A2S2 is an interlock safety switch manufactured by Honeywell Sensing and Productivity Solutions. This component is classified as obsolete and is no longer in active production. The product carries RoHS Compliant certification and features unlimited moisture sensitivity level (MSL 1). Due to its obsolete status, identification of functionally equivalent substitute components is necessary for system maintenance, repair, and new design implementations where interlock safety switching functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GKLB2A2S2 is based on the following criteria derived from provided specifications:

Primary Substitution Basis:

• Functional category: Interlock safety switching
• RoHS compliance requirement: RoHS Compliant status maintained
• Moisture sensitivity level: MSL 1 (Unlimited) compatibility
• Electrical switching capability: DPST circuit configuration

Identified Substitute: The SG-B1-MA-G5 manufactured by Panasonic Industrial Automation Sales qualifies as a substitute based on:

• Active product status (current availability)
• RoHS3 Compliant certification (meets RoHS requirement)
• MSL 1 (Unlimited) rating (matches moisture sensitivity specification)
• DPST-NC circuit configuration (dual-pole switching capability)
• Solenoid release interlock functionality (equivalent operational purpose)

Parameter Comparison

Engineering Selection Recommendations

For GKLB2A2S2 Replacement:

The SG-B1-MA-G5 is the designated substitute component. Selection is based on the following engineering factors:

1. Compliance Status: Both components meet RoHS requirements. The SG-B1-MA-G5 carries ROHS3 Compliant certification, representing current compliance standards.

2. Product Availability: The GKLB2A2S2 is obsolete. The SG-B1-MA-G5 maintains active product status with current manufacturing support and documented inventory availability (954 Pcs).

3. Moisture Sensitivity: Both components share MSL 1 (Unlimited) rating, ensuring equivalent environmental tolerance in storage and handling.

4. Regulatory Certifications: The SG-B1-MA-G5 carries CE, cULus, and TUV approvals, providing multi-regional compliance documentation suitable for industrial applications.

5. ECCN Classification: The substitute component is classified as EAR99, indicating standard commercial export classification versus the obsolete designation of the original part.

Implementation Consideration: Electrical parameters (current rating, voltage specifications, circuit configuration) for the SG-B1-MA-G5 must be verified against system requirements prior to integration, as the original GKLB2A2S2 specifications do not include detailed electrical parameters for direct comparison.

Frequently Asked Questions (FAQ)

Q: Why is the GKLB2A2S2 no longer available?

A: The GKLB2A2S2 is classified as obsolete and has been discontinued by Honeywell Sensing and Productivity Solutions. Obsolete status indicates the manufacturer no longer produces or supports this component.

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

A: The SG-B1-MA-G5 qualifies as a substitute based on matching functional category (interlock safety switching), equivalent RoHS compliance status, identical MSL 1 rating, and active product status with current manufacturing support.

Q: Are there packaging differences between these components?

A: The GKLB2A2S2 packaging is not specified in available documentation. The SG-B1-MA-G5 is supplied in Bulk packaging. Packaging compatibility must be evaluated based on specific application requirements.

Q: What electrical parameters should I verify before substitution?

A: The original GKLB2A2S2 does not include documented electrical specifications. For the SG-B1-MA-G5 substitute, verify that the following parameters align with system requirements: 2A current rating (AC/DC), 125VAC/30VDC voltage rating, 24VDC supply voltage, and DPST-NC circuit configuration.

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

A: The SG-B1-MA-G5 is rated IP67 (Dust Tight, Waterproof) with operating temperature range -25°C ~ 70°C. The original GKLB2A2S2 environmental specifications are not documented, so environmental equivalence cannot be confirmed from available data.

Q: What certifications does the substitute component carry?

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

Q: Is the SG-B1-MA-G5 currently in stock?

A: Yes, 954 Pcs of new original SG-B1-MA-G5 components are documented as in stock. The original GKLB2A2S2 has 837 Pcs available as new original stock, though this component is obsolete.
