Key Features
- SPDT 5 A contact rating handles both resistive and moderate inductive loads at up to 250 V AC
- 24 V DC coil voltage with non-latching (monostable) operation for fail-safe de-energized states
- Compact 6 mm plug-in form factor simplifies PCB layout in space-constrained control boards
- Low coil power consumption reduces thermal load in dense relay-array designs
Applications
The HF41F-024-ZT is widely used in industrial automation panels, home appliance control boards, and building management systems where a compact 24 V DC relay is needed to switch mains-level loads up to 5 A. Its plug-in 6 mm package makes it easy to replace in field-service scenarios without soldering. HVAC controllers, smart lighting modules, and motor soft-start circuits frequently incorporate this relay for its combination of small footprint and reliable SPDT switching performance.

Frequently Asked Questions
What coil voltage and switching current can the HF41F-024-ZT handle?
The HF41F-024-ZT operates on a 24 V DC coil and provides SPDT contact switching rated at 5 A, making it suitable for controlling loads such as solenoids, small motors, and 250 V AC mains circuits. The non-latching design ensures the relay returns to its default state whenever coil power is removed, supporting fail-safe system logic.
How does the 6 mm plug-in package of the HF41F-024-ZT simplify field maintenance compared to soldered relays?
The 6 mm plug-in format allows the HF41F-024-ZT to be removed and replaced on a PCB socket without re-soldering, reducing mean time to repair in industrial panels and appliance control boards where relay contacts wear out over many switching cycles. This is particularly beneficial in HVAC control boards cycling loads hundreds of thousands of times per year.
When is the HF41F-024-ZT a better fit than a solid-state relay for a 24 V DC switching application?
The HF41F-024-ZT is preferable when the application requires very low on-state voltage drop, bidirectional AC switching at 5 A, or physical circuit isolation between control and load sides, all of which mechanical relays provide at lower cost than comparable solid-state alternatives. Its SPDT configuration also allows both normally-open and normally-closed load paths from a single 24 V coil.
