Sourcing 80440-SZ5-003 from Professional Supplier FAQs

How does your 80440-SZ5-003 handle the dual-brand fitment for Acura and Toyota?

As a specialized B2B manufacturer, we produce this switch with two precision-machined thread options: M11-P1.0 for Acura/Honda systems and 3/8-24 UNF for Toyota/Lexus systems. While the internal 4-pin pressure logic is identical, we ensure the fitting is exact to your target market's requirements, reducing return rates for your distribution network.

What is the benefit of the 1.52Mpa Medium Pressure (MP) logic in this switch?

This switch is a true trinary sensor. The 1.52Mpa threshold is specifically calibrated to manage cooling fan engagement or compressor modulation. This prevents head pressure spikes in heavy traffic, ensuring the HVAC system in your clients' luxury vehicles operates at peak efficiency without overheating.

Can we request private label laser marking for our own brand of HVAC parts?

Yes. For our wholesale partners and top 100 importers, we offer full private label services. We can laser-etch your logo and the 80440-SZ5-003 / 88645-20050 OE numbers directly on the aluminum housing, accompanied by custom-branded professional packaging to enhance your brand authority.

What is your standard lead time for wholesale orders?

Our fixed manufacturing lead time is 60 days. This duration is strictly necessary to maintain our IATF 16949 standards, which includes precision diaphragm calibration and high-pressure helium leak testing for each batch to ensure zero-defect delivery to your international warehouse.

Do you offer flexible payment terms for established long-term importers?

We prioritize long-term cooperative partnerships. While initial orders follow standard T/T terms, we provide flexible credit vetting for established clients with a consistent order history. Our goal is to support your cash flow and facilitate large-scale, high-frequency procurement cycles.

How is the product protected during international maritime or air freight?

Every pressure switch is individually sealed in moisture-proof industrial packaging. For bulk wholesale orders, we utilize reinforced cartons with internal shock-absorbing dividers and palletized shipping to ensure the 4-pin electronic terminals and M11/3/8 threads remain in perfect condition during transit.
