Magnetic Lock Questions Buyers Ask Most

Answers to help you specify, quote and order with confidence.

What is the difference between fail-safe and fail-secure magnetic locks?
A fail-safe electromagnetic lock releases the door automatically when power is cut — this is the design used in all OUBAO magnetic locks. It ensures occupants can exit freely during power failures or fire emergencies, meeting international fire safety and emergency egress codes. A fail-secure lock remains locked when power is lost. For applications requiring fail-secure operation, consider electric bolt locks or electric strike locks instead.
How do I choose the right magnetic lock holding force?
Magnetic lock holding force selection depends on door weight, door width, and security level. A 400 lb magnetic lock (OB180, 180kg) suits lightweight interior doors. The 600 lb magnetic lock (OB280/CK280, 280kg) is the industry standard for commercial magnetic lock applications. A 1200 lb magnetic lock (OB500, 500kg) is recommended for fire-rated doors and heavy entries. The 1500 lb magnetic lock (OB700, 700kg) serves maximum-security installations, while the 1600 lb magnetic lock (OB750, 750kg) is built for the most demanding high-traffic, high-risk entries. All OUBAO series support wooden, glass, and metal door magnetic lock installation.
Can magnetic locks be used on fire-rated doors?
Yes. All OUBAO electromagnetic locks feature fail-safe operation, meaning they automatically release on power failure — a requirement for fire door installations. This fail-safe design ensures unobstructed emergency egress, meeting the international fire safety and building codes required for fire-rated door projects.
What is the difference between surface mount and mortise mount?
Surface mount (H-suffix models, e.g. OB280H): The lock body is mounted on the door frame surface. Faster to install, easier to retrofit. Mortise mount (F-suffix models, e.g. OB280F): The lock body is recessed into the door frame for a flush finish. Preferred for architectural aesthetics. Both offer the same holding force and security performance.
What is the difference between the OB280 and CK280?
Both deliver 280kg (600lbs) holding force, but serve different market segments. The OB280 uses a precision-machined armature plate with ±10% tolerance and is UL Listed. The CK280 uses a silicon steel lamination core with ±15% tolerance, certified with CE/FCC/RoHS/REACH — a cost-effective option for projects that do not require UL certification.
Do your magnetic locks support access control system integration?
Yes. Models with the “A” suffix (e.g. OB280HA, OB500HA) include NO/COM or NO/COM/NC signal output for door status monitoring. Selected models feature indicator lights and adjustable time delay (0–10s). Every series is available as a 12V magnetic lock or 24V magnetic lock, compatible with standard access control panels, card readers, keypads, and face recognition systems. This makes the OUBAO magnetic lock system ideal for both standalone and networked magnetic lock access control installations.
What is the MOQ and lead time for OEM/ODM orders?
As a magnetic lock manufacturer with dedicated factory production lines, our MOQ typically ranges from 300 to 1,000 units depending on the series and customization scope. Standard lead time is 35 days from order confirmation. We support magnetic lock OEM customization including private-label branding, custom voltage, housing color, cable length, and tailored packaging. For magnetic lock wholesale and bulk orders above 5,000 units, contact our sales team for volume pricing and expedited production.
How is a surface mount magnetic lock installed?
Magnetic lock installation varies by type. A surface mount magnetic lock is fixed directly to the door frame header with screws — typically a 30-minute magnetic lock installation by a qualified technician. A mortise magnetic lock requires routing a recess into the frame for a flush fit. Both types connect to 12V or 24V DC power supply and integrate with your access control panel. Our technical team provides magnetic lock installation guides and dimensional drawings with every order.
How is magnetic lock price determined for bulk orders?
Magnetic lock price depends on the series (holding force), order quantity, and OEM customization requirements. As a direct magnetic lock factory, OUBAO offers competitive magnetic lock price advantages compared to trading companies — you buy directly from the manufacturer with no middleman markup. Contact our sales team with your project specifications and quantity for a detailed magnetic lock bulk quote.
