Engineering Selection Recommendations

For Obsolete Component Replacement:

The SG-B1-MA-G5 represents an active production alternative to the obsolete GKLE44PXT2. Selection of the SG-B1-MA-G5 is supported by the following engineering factors:

• Product Status Alignment: The SG-B1-MA-G5 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Certification: Both components meet RoHS requirements. The SG-B1-MA-G5 additionally holds CE, cULus, and TUV certifications, providing broader regulatory acceptance.
• Environmental Protection: The SG-B1-MA-G5 provides IP67 ingress protection, exceeding typical interlock switch environmental requirements.
• Moisture Handling: Both components share MSL 1 rating, indicating equivalent moisture sensitivity performance.

Application Verification Required:

Before final component selection, verify that the SG-B1-MA-G5 electrical specifications (125VAC/30VDC contact rating, 24VDC supply voltage, 2A current capacity) align with the target application requirements. The operating temperature range of -25°C to 70°C must accommodate the intended installation environment.

Frequently Asked Questions (FAQ)

Q: Why is the GKLE44PXT2 classified as obsolete?

A: The GKLE44PXT2 has reached end-of-life status with Honeywell Sensing and Productivity Solutions. No new production is scheduled. Existing inventory of 1138 units represents the remaining available supply.

Q: What makes the SG-B1-MA-G5 a valid substitute for the GKLE44PXT2?

A: Both components function as interlock safety switches with identical Moisture Sensitivity Level (MSL 1) and RoHS compliance. The SG-B1-MA-G5 is an active production component with enhanced environmental protection (IP67) and multiple regulatory certifications (CE, cULus, TUV).

Q: Are there electrical compatibility concerns when switching from GKLE44PXT2 to SG-B1-MA-G5?

A: The SG-B1-MA-G5 operates at 125VAC/30VDC contact rating with 24VDC supply voltage and 2A current capacity. Confirm these specifications match your application requirements before implementation.

Q: What is the packaging difference between these components?

A: The GKLE44PXT2 packaging specification is not provided in available documentation. The SG-B1-MA-G5 is supplied in Bulk packaging format.

Q: How does the operating temperature range affect substitution?

A: The SG-B1-MA-G5 operates across -25°C to 70°C. Verify this range encompasses your installation environment. The GKLE44PXT2 operating temperature is not specified in available data.
