Application Scenarios: Forklift handle control and mast limit, electric pallet truck lifting start-stop control, loader gear and boom limit
Core Functions: Operation instruction signal acquisition, stroke limit overload protection, safety interlock status feedback, mechanism in-place reset detection
Core Advantages: Long travel compatible with large tolerance, sealed design for dust, oil and dirt resistance, long service life for high-frequency operations, strong universality and easy maintenance
Pain Points Solved: Unstable triggering under large assembly tolerance, contact failure in harsh working conditions, easy component damage from collision without limit protection, high operation and maintenance cost under high-frequency use
Product advantages:
Precisely adapts to air conditioning application scenarios
The waterproof and dustproof design meets IP protection standards, effectively resisting moisture and dust intrusion in the air conditioning operating environment, and preventing contact oxidation and malfunction.
Using high-quality contact materials and precision manufacturing processes, the low resistance characteristics ensure efficient circuit switching, reducing energy consumption and heat generation, making it suitable for key control scenarios such as air conditioning fan operation and compressor start-stop.
Enhanced with high mechanical durability, it can withstand over a million cycles of operation, meeting the long-term continuous operation requirements of air conditioning and reducing the frequency of equipment maintenance.
