Round Size Hidden Magnetic Contact Sensor
The round size hidden magnetic contact sensor is a compact device that combines a glass‑encapsulated reed switch with nickel‑iron contacts, an ABS plastic housing and a neodymium magnet. Its design enables concealed installation behind doors or windows, where it monitors magnetic field changes caused by a paired magnet moving away. When the magnetic field is altered, the reed switch closes or opens, generating an alarm signal for security systems. The sensor is supplied in bulk packaging suitable for global export.
The glass‑encapsulated reed switch provides reliable operation under normal indoor temperature ranges, while the ABS housing protects the internal components from dust and minor impacts. Neodymium magnets deliver a strong magnetic field, allowing a detection gap of a few millimetres, which matches typical specifications for concealed security sensors. Manufacturers often select this construction for residential and commercial alarm installations because it balances durability with a low profile.
These sensors are widely used in residential and commercial security alarm systems, access‑control doors and smart‑home automation where discreet monitoring is required. Buyers such as system integrators, OEMs and ODMs can request custom quantities and receive the units in bulk cartons for efficient shipping. The supplier offers standard and customised solutions and can arrange export logistics to most ports worldwide, subject to confirmation of minimum order quantities and Incoterms.

Sourcing Round Size Hidden Magnetic Contact Sensor from ShenZhen Cian Electronics Co., LTD - China Import Guide
Before placing an order, verify the exact operating distance, supply voltage and contact current rating that match your system requirements. Request a sample or a data sheet that lists the glass‑encapsulated reed switch type, housing material and magnet grade. Confirm whether the supplier can provide any certifications such as IEC 60730 or UL 1577, and ask for the minimum order quantity and packaging details.
Discuss the preferred Incoterms, such as FOB Shenzhen or CIF Shanghai, and clarify the expected lead time for production and shipment. Because the supplier’s response rate is listed as zero, allow extra time for communication and negotiate clear timelines in the contract. Payment terms are not disclosed, so request whether they accept T/T, L/C or other arrangements and whether a deposit is required.
Arrange for a pre‑shipment inspection that includes functional testing of the reed switch at the specified voltage and current. Ask the supplier to provide a test report showing insulation resistance and temperature performance, together with a Certificate of Conformity if available. Retain the original packing list, commercial invoice and any material safety data sheet for customs clearance and future warranty claims.
