MWS10A Industrial Microwave Motion Sensor – Fast, reliable activation for doors, gates, and lighting

The MWS10A is a compact microwave Doppler motion sensor designed for automating door/gate activation and presence-based lighting control. From my experience, this model suits busy logistics bays, warehouse aisles, and production corridors where you need quick detection with fewer false triggers than PIR alone. You might notice that it picks up motion reliably even when ambient temperature shifts, which is often where PIR sensors struggle.

Company’s Order Placement Process and Guarantees

• – Warranty period: 365 days

• – Delivery time: 1 week for in-stock items; no more than one month at the latest

We typically pre-test and document sensor output behavior before dispatch, so commissioning on site is smoother. If you’re matching an existing system, share a photo of the current unit or terminal layout—we’ll cross-check pinout and mounting hole positions to avoid surprises.

Key Features

• Microwave Doppler sensing – Detects motion with high stability, typically less sensitive to temperature swings and airflow compared with PIR.
• 12–24 V AC/DC supply – Flexible power options suit most door controllers and lighting relays.
• Relay output (dry contact) – Simple NO/NC switching into existing control circuits without protocol headaches.
• Adjustable sensitivity and hold time – Tune detection range and output duration to reduce nuisance triggers.
• Compact, low-profile housing – Fits neatly above a door header or in a ceiling void.
• Indoor industrial use – In many cases performs well in warehouses, loading docks, and production corridors.
• Aimable detection field – Typically allows angle and range adjustments to focus on traffic zones and ignore side activity.
• Stable in challenging environments – Tends to work better than PIR near HVAC outlets or sun-exposed entries.

Technical Specifications

Related or Supporting Products

• MWS12-series microwave sensors – Similar function with a wider/deeper detection field for higher mounting points.
• High-bay microwave sensors (e.g., 10–15 m) – For tall warehouse ceilings; typically higher output power and narrower beam.
• PIR sensors (ceiling mount) – Lower cost; pair with MWS10A for dual-technology logic to reduce false triggers.
• Industrial door controllers – Standard relay inputs; MWS10A connects as an activation device (dry contact).
• Weather hoods and surface back-boxes – Useful when installing near dock doors or semi-outdoor vestibules.

A maintenance lead at a 3PL site told us, “We swapped two PIRs for the MWS10A above the roll-up door—early mornings stopped false openings from sun glare. The relay wiring was plug-and-play.”

Installation & Maintenance

• Mounting environment – Install on a rigid surface above the activation area; avoid pointing directly at vibrating machinery or moving curtains.
• Cabinet/box standards – If mounted in a box, use a non-metallic cover or plastic window; metal housings can attenuate the microwave field.
• Wiring – 12–24 V AC/DC to power; relay dry contact to controller input. Keep power and signal runs short and separated from VFD motor cables where possible.
• Ventilation – No active cooling needed; maintain airflow and keep away from heat sources above 55 °C.
• Sensitivity & timing – Start mid-range, then trim sensitivity and hold time to match traffic density; use angle adjustment to exclude cross-traffic.
• Safety – Isolate power before wiring; confirm NO/NC logic matches the door controller’s expectations to avoid unintended operation.
• Routine care – Quarterly dust wipe of the sensor face; verify detection zone and relay operation after any layout changes. Firmware updates are not typically required for this class of device.

Quality & Certifications

• CE and RoHS compliance in most cases for this category of microwave motion sensors.
• UL/cUL recognition may vary by production batch and region—please confirm if you need a specific listing on the label.
• Manufacturer’s warranty is typically 12 months; our coverage is 365 days from shipment as noted above.
• Each unit is function-tested prior to shipment to verify relay switching and basic detection behavior.
