Motion Detector – Narrow Field Beam

Solution

Narrow Beam motion detector for tight spaces to minimize false detection signals from other areas.

Description

The PS-VMD-NB is a microwave motion detector engineered for precision vehicle, pedestrian, and bicycle detection in narrow zones. Designed for covered garages and tight spaces, it eliminates false detections from adjacent traffic by focusing on a 3–6 ft. beam path width. It’s ideal for activating safety signs, gate controls, access systems, and automatic doors in smart traffic environments.

Works with vehicles, bicycles, and pedestrians
Narrow beam (3–6 ft) for targeted motion detection
Adjustable output time (1–6 seconds)
Wall or ceiling mount up to 15 ft high
Built-in LED for activation feedback
Dry contact relay output – normally open
Durable ABS housing – IP54 rated
Compatible with all PASS Controllers

When the PS-VMD-NB Narrow Beam Motion Detector identifies motion within its detection zone — whether from a vehicle, bicycle, or pedestrian — the sensor activates an internal microwave detection circuit. This circuit responds to motion across a narrow 3 to 6-foot path, ensuring precise targeting and minimizing false detections.

Once motion is detected:

The relay output is triggered immediately (within approximately 0.5 seconds). The normally open (NO) dry contact closes, completing the circuit.

This contact closure can:

Activate a connected Parking Alert Sign
Trigger a controller, door opener, gate operator, light, or alarm.
The relay remains closed for 1 to 6 seconds, depending on the configured hold time (adjustable).
After the delay expires and no further motion is detected, the contact opens again, returning the system to standby.
An activation LED on the unit provides real-time feedback, flashing during motion detection and relay activation. The output is isolated, allowing it to safely interface with low-voltage control systems, including the PASS Controller and other automation devices
