EMX 5410-2 HAWK 2 Microwave Motion Sensor Technical Details
The EMX 5410-2 HAWK 2 is an overhead K-band microwave motion sensor designed to activate automatic doors, industrial doors, gates, and other access-control equipment when movement is detected within its programmed field. The sensor operates at 24.150 GHz and can detect both moving vehicles and pedestrians.
The HAWK 2 is designed for relatively straightforward motion-detection applications where vehicle-versus-pedestrian discrimination and stationary presence detection are not required. Its detection field, sensitivity, direction of travel, relay behavior, and output hold time are adjusted directly at the sensor without a programming remote.
What the HAWK 2 Does
The HAWK 2 continuously monitors its microwave detection field for movement. When qualifying movement occurs, its Form C relay changes state and sends an activation signal to the connected automatic door, gate operator, industrial door controller, or access-control equipment.
The sensor can be configured for bidirectional detection or for movement in only one direction. In monodirectional mode, the installer can select approaching or departing traffic.
- Detects moving vehicles and pedestrians
- Adjustable detection range from approximately 3-33 ft
- Approaching, departing, or bidirectional detection
- Wall or ceiling mounting
- Adjustable sensor angle for accurate field placement
- Adjustable sensitivity and detection range
- Adjustable 1-6 second relay hold time
- One Form C SPDT relay output

Typical Applications
- Commercial overhead doors
- High-speed roll-up doors
- Industrial doors
- Automatic pedestrian doors where motion activation is appropriate
- Automatic gate activation
- Parking and access-control entrances
- Applications where cutting an inductive roadway loop is undesirable
Important Detection Limitation
The HAWK 2 detects motion but does not distinguish a vehicle from a pedestrian. If a person moves through the configured microwave field, the sensor can activate just as it would for a moving vehicle.
The HAWK 2 also does not provide stationary presence detection. Once movement stops, the output releases after the selected relay hold time. Applications requiring vehicle-versus-pedestrian discrimination, cross-traffic rejection, or stationary presence detection should be evaluated for a different sensor such as the EMX RAVEN or OWL.

Directional Detection Settings
The HAWK 2 can be configured for bidirectional or monodirectional detection.
- Bidirectional: Relay activates for qualifying motion moving either toward or away from the sensor.
- Approaching: Relay activates only for motion approaching the sensor.
- Leaving: Relay activates only for motion moving away from the sensor.
Direction is selected using internal DIP switches. This can help prevent activation from traffic traveling in an unwanted direction, but it does not provide cross-traffic rejection comparable to the more advanced EMX RAVEN or OWL.
Sensitivity and Detection Range Adjustment
The HAWK 2 uses a high/low sensitivity DIP switch together with a range adjustment control. After selecting the basic sensitivity level, the range control is used to fine-tune the desired detection area.
The manufacturer lists an adjustable detection range from approximately 3 to 33 ft. Actual field dimensions depend on sensor height, mounting angle, sensitivity setting, target size, direction of travel, and installation environment.
Adjustable Relay Hold Time
The output period can be adjusted from approximately 1 to 6 seconds. This determines how long the relay remains activated after motion is no longer detected.
The HAWK 2 is therefore a motion detector rather than a true presence detector. A stationary vehicle or person should not be expected to hold the output indefinitely.
Relay Wiring
- Red - 12-24 VAC/VDC power
- Black - 12-24 VAC/VDC power
- Green - Relay Common
- Brown or Yellow - Relay Normally Open
- Blue - Relay Normally Closed
Verify the wire colors on the actual sensor and follow the current EMX manual before connecting the HAWK 2. Do not copy wiring from a RAVEN, OWL, or another microwave sensor because output arrangements can differ.
Normal and Positive-Safety Relay Settings
The HAWK 2 includes a DIP-switch setting that changes the relay contact state between Normal Operation and the manufacturer's Positive Safety configuration. This changes how the relay contacts behave during detect and no-detect conditions.
This relay setting should not be confused with monitored gate entrapment protection. The HAWK 2 remains a motion activation sensor and does not replace UL 325 monitored photo eyes, sensing edges, or other required safety devices.
Installation Location Considerations
EMX specifies mounting the HAWK 2 approximately 10-20 ft above the monitored area. The sensor can be installed on a wall or ceiling and mechanically aimed toward the desired detection zone.
EMX specifically advises against installing the HAWK 2:
- Facing moving portions of the door
- Facing fluorescent lighting located closer than approximately 6.5 ft
- Facing areas where flowing rainwater could create unwanted movement
After installation, test the complete detection field with representative vehicles and pedestrian movement. Adjust range and sensor angle until the desired activation zone is established.
HAWK 2 vs. RAVEN vs. OWL
| Feature | HAWK 2 | RAVEN | OWL |
| Technology | Microwave | Microwave | Microwave plus active infrared |
| Detection Type | Motion | Motion | Motion and presence |
| Differentiate People and Vehicles | No | Yes | Yes |

These sensors are related products but should not be treated as direct substitutes without checking the application's detection requirements, wiring, mounting height, output requirements, and safety functions.

Installation and Safety Advisory
The HAWK 2 is an activation and motion-detection accessory. It should be installed according to the EMX instructions and the automatic door or gate operator manufacturer's requirements. After installation, test the complete detection area and operator response with representative traffic.
The HAWK 2 does not replace monitored photo eyes, sensing edges, inherent entrapment protection, door reversal systems, or other required safety devices. Never use relay programming or sensor placement to bypass a required safety circuit. If the proper operator input, relay configuration, mounting location, or safety requirements are unclear, use a qualified automatic-door, gate, or access-control technician.
Product Questions and Answers
What is the EMX 5410-2 HAWK 2?
The EMX 5410-2 HAWK 2 is an overhead 24.150 GHz K-band microwave motion sensor for automatic doors, industrial doors, gates, and access-control applications. It detects movement within an adjustable field and provides one Form C relay output.
Can the EMX HAWK 2 tell the difference between a vehicle and a person?
No. The HAWK 2 can detect moving vehicles and pedestrians but cannot distinguish between them. Applications requiring vehicle-versus-pedestrian discrimination should be evaluated for an EMX RAVEN or OWL sensor.
What is the detection range of the EMX HAWK 2?
EMX specifies an adjustable detection range of approximately 3-33 ft. Actual coverage depends on mounting height, sensor angle, sensitivity, target size, and installation conditions.
What mounting height is recommended for the HAWK 2?
The EMX installation manual specifies mounting the HAWK 2 between approximately 10 and 20 ft above the detection area. The sensor can be aimed mechanically to position the microwave field where needed.
Can the HAWK 2 detect only approaching vehicles?
Yes. The HAWK 2 can be configured for bidirectional motion or monodirectional operation. In monodirectional mode, it can be set to detect either approaching or departing movement.
Does the HAWK 2 provide stationary vehicle presence detection?
No. The HAWK 2 is a motion sensor. Its relay hold time is adjustable from approximately 1-6 seconds after motion ends, so it should not be selected as a substitute for a true stationary presence detector.
What voltage does the EMX 5410-2 require?
The HAWK 2 operates from 12-24 VAC or VDC and draws a maximum of approximately 40 mA with the relay activated. Verify the available power supply before connection.
What is the difference between the EMX HAWK 2, RAVEN, and OWL?
The HAWK 2 provides basic microwave motion detection and cannot distinguish people from vehicles. The RAVEN adds vehicle-versus-pedestrian discrimination, cross-traffic rejection, and two relay outputs. The OWL combines microwave motion with infrared presence detection and also distinguishes different traffic types.
