Door Window Sensor Manufacturer | Zigbee & WiFi OEM/ODM

A door window sensor is a two-part magnetic contact that reports whether a door or window is open or closed, and can trigger an alarm, a notification or an automation scene the moment it changes state. Xingliao manufactures door and window sensors, motion sensors and related detectors in Shenzhen for overseas brands and distributors, supplied as OEM or ODM running on Tuya, Zigbee or Wi-Fi.

What Is a Door Window Sensor?

The sensor has two halves: a magnet fitted to the moving leaf of the door or window, and a contact body mounted on the fixed frame. While they sit close together the circuit reads closed; when the leaf opens, the magnetic field drops away and the device reports open. Because it only watches a state rather than streaming video, a single coin cell typically powers it for a long period, which is why these sensors are used in such large numbers across security and automation projects.

That low cost and long battery life are exactly why distributors source them alongside switches and cameras: they are the cheapest way to give a homeowner a complete system rather than isolated devices, and they drive recurring sales of every other category in the range.

Detector Types We Manufacture

• Door and window contact sensor — the standard two-part reed switch unit, available in standard or slim profiles for narrow frames.
• Motion sensor (PIR) — detects body movement across a room, used for occupancy scenes as much as for alarm triggering.
• Vibration and tilt sensors — mounted on garage doors, shutters and valuable objects where a contact will not fit.
• Water leak detector — placed under sinks, boilers and washing machines to alert before damage spreads.
• Temperature and humidity sensors — paired with HVAC scenes or cold-chain monitoring.
• Combined keys and panic buttons — portable triggers for assisted living and emergency scenes.

Zigbee or Wi-Fi: The Decision That Shapes the Usable Range

Detector choice is really a protocol choice, because the two options behave very differently at scale.

• Zigbee versions — run on tiny coin cells for extended periods, build a mesh that extends itself as you add devices, and need a gateway. This is the right answer for a whole-home system with dozens of sensors.
• Wi-Fi versions — talk directly to the router with no gateway, which suits single-point use such as one alert about a front door. The trade-off is higher power draw and more load on the customer's router.

Most of our private-label partners carry both: a Wi-Fi unit for entry-level retail packs and a Zigbee unit for project bundles that include a smart home gateway. We will help you decide the ratio from your channel mix rather than guessing.

What the Sensor Can Trigger

• Alarm and notification — push alerts to the homeowner's phone when a door opens while nobody should be home.
• Arming modes — home, away and night modes with different detectors active in each.
• Lighting scenes — switching a hallway light on when a door opens after dark, using the contact as a trigger rather than a separate switch.
• Energy logic — cutting air conditioning when a window is opened.
• Voice announcement — playing a chime through compatible speakers and displays.

These behaviours are configured in the Tuya or Smart Life platform, so your customers get them without you writing app code.

OEM and ODM Customisation

1. Branding — logo on the housing, branded retail packaging and multilingual inserts.
2. Protocol and chipset — Zigbee or Wi-Fi variants specified per SKU.
3. Housing — profile, colour and mounting method, including adhesive versus screw fixing.
4. Firmware identity — device name shown in the app, default scenes and reporting interval.
5. Kit assembly — bundled into starter packs with a gateway or siren under one barcode.

Programme minimums start from 500 pieces per model for standard configurations. Tooling projects carry their own engineering fee and unit commitment, quoted per project.

Frequently Asked Questions

Do Zigbee door sensors need a hub?

Yes. Zigbee models pair to a Zigbee gateway, which normally ships in the same project bundle. Wi-Fi models connect to the router directly and need no hub.

How long does the battery last?

Contact sensors sit idle most of the time and are optimised around coin-cell operation, so replacement intervals are measured in extended periods rather than weeks. Actual life depends on reporting frequency and how often the door is used.

Can these trigger lights as well as alarms?

Yes. Within the Tuya or Smart Life ecosystem an open contact can start a lighting scene, adjust air conditioning or play a chime, not only raise an alarm.

Can we sell them in starter kits?

Yes. We regularly bundle several sensors with a gateway or siren into one retail pack with a single barcode, which is how many distributors introduce an automation range.

What is the minimum order quantity?

Standard configurations begin at 500 pieces per model. Custom-tooled projects are quoted separately with their own engineering fee.

Which certifications come with shipments?

CE, FCC and RoHS documentation with the corresponding test reports, plus Radio approvals where the destination market requires them.
