Parameter Comparison

Engineering Selection Recommendations

The GLHB24A1B is a direct equivalent substitute for the obsolete GLHC24A1A. Both parts are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series and share identical electrical, mechanical, and environmental specifications.

Selection Basis:

The GLHB24A1B maintains full compatibility across all critical parameters: DPDT circuit configuration, 6A DC / 30V DC rating, side rotary roller actuator, chassis mount configuration, screw terminal termination, IP67 ingress protection, and identical mechanical travel specifications. Both parts operate across the -25°C to 85°C temperature range and deliver 15,000,000 mechanical cycles.

The primary distinction is product status: the GLHC24A1A is obsolete while the GLHB24A1B is active. Both parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.

For applications requiring the GLHC24A1A, the GLHB24A1B provides functional and mechanical interchangeability without design modification or system reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the GLHB24A1B directly replace the GLHC24A1A in existing installations?

A: Yes. The GLHB24A1B is electrically and mechanically equivalent to the GLHC24A1A. Both parts feature identical DPDT circuit configuration, 6A DC / 30V DC ratings, side rotary roller actuators, chassis mount design, screw terminal termination, and mechanical specifications. No circuit modifications or mechanical adjustments are required.

Q: What is the difference between the GLHC24A1A and GLHB24A1B?

A: The parts are functionally identical across all electrical and mechanical parameters. The primary difference is product status: GLHC24A1A is obsolete, while GLHB24A1B is active. Additionally, the roller material differs (nylon in GLHC24A1A versus steel in GLHB24A1B), though both meet the same operational specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the GLHC24A1A and GLHB24A1B are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.
