Optex OVS-01GT Vehicle Presence Sensor, Loop Detector, No Inground Loop Required
***REPLACED WITH THE OVS-02GT ***
The Optex OVS-01GT is an above-ground vehicle presence sensor designed for automatic gates, barrier gates, and industrial door applications. It is often used when a traditional in-ground loop detector is not practical because the driveway cannot be cut, the pavement is already finished, the surface is uneven, or trenching would be too expensive.
Instead of using a saw-cut loop wire buried in the pavement, the OVS-01GT mounts above ground near the gate, barrier, or operator. It uses dual sensing technology to detect a vehicle in the target area and then provides an output to the connected operator or access-control equipment. In many gate applications, this makes it a useful replacement or alternative to a traditional loop detector system.
The OVS-01GT is designed to detect stationary or moving vehicles while ignoring most human traffic when properly installed and adjusted. It is commonly used for gate activation, vehicle presence detection, barrier arm applications, industrial door applications, and locations where a clean above-ground installation is preferred over cutting a loop into concrete or asphalt.

What This Sensor Does
The OVS-01GT detects a vehicle in the selected detection zone and sends a relay/output signal to the connected gate operator, barrier arm, industrial door operator, or access-control device. It can be used to help identify when a vehicle is present near the entrance, exit, or control point.
Because it is mounted above ground, the sensor can often be installed faster than a conventional loop system. It also allows the detection area and settings to be adjusted from the mounted sensor location instead of replacing or troubleshooting buried loop wire.
Common Applications
- Vehicle presence detection at automatic gates
- Barrier arm vehicle detection
- Slide gate vehicle detection where an in-ground loop is not practical
- Industrial door vehicle detection
- Exit or activation detection where approved by the operator setup
- Parking, commercial entrance, and facility access-control applications
- Locations where concrete cutting, asphalt cutting, trenching, or loop wire installation is not desired
- Retrofit jobs where the original in-ground loop has failed or cannot be repaired easily
Compatible With
The Optex OVS-01GT is intended for select automatic gate, barrier, and industrial door applications that can accept a compatible sensor relay/output signal. Compatibility depends on the operator input, power source, wiring method, detection function, mounting location, and safety requirements of the system.
- Automatic slide gate operators with compatible vehicle detection inputs
- Automatic swing gate operators with compatible vehicle detection inputs where the detection layout is appropriate
- Barrier gate operators with compatible vehicle detection or activation inputs
- Industrial door operators with compatible low-voltage control inputs
- Access-control systems requiring a vehicle presence signal where the relay/output function is suitable
- Vehicle activation and presence applications where an above-ground virtual loop is preferred
- Retrofit applications where an in-ground loop detector is damaged, missing, or impractical
Do not choose this sensor by operator brand alone. A LiftMaster, DoorKing, HySecurity, Linear, Viking, FAAC, Nice/Apollo, All-O-Matic, BFT, CAME, or other operator may be compatible only if the OVS-01GT is powered correctly, mounted in the correct location, and wired to the correct input for the intended function.
Not Intended For
- Replacing monitored photo eyes or safety edges
- Bypassing required entrapment protection devices
- Pedestrian detection
- Wiegand reader data replacement
- Remote control receiver replacement
- Telephone entry or keypad replacement
- Loop counter applications unless the full system design supports that use
- High-speed traffic applications outside the approved detection range and vehicle speed limits
- Locations where the sensor cannot be mounted with a clear view of the vehicle detection area
- Applications requiring an in-ground loop specifically for the operator or safety design
Important Safety and Application Warning
The Optex OVS-01GT is a vehicle presence sensor. It is not a replacement for required monitored entrapment protection, photo eyes, safety edges, UL 325 safety devices, gate warning signs, or proper gate hardware. Do not use this sensor to bypass required safety inputs on a gate operator.
Vehicle detection and pedestrian safety are different functions. The OVS-01GT is designed to detect vehicles while ignoring most human movement. That is useful for vehicle-only detection, but it also means it should not be relied on as a pedestrian protection device.
No In-Ground Loop Required
Traditional loop detectors require saw-cutting pavement, laying loop wire, sealing the cut, and wiring the loop back to a detector module. The OVS-01GT avoids that buried loop wire step by using an above-ground sensor mounted near the gate, barrier, or operator.
This can be especially helpful on existing driveways, finished concrete, pavers, asphalt, rental properties, sites with difficult trenching, or locations where the loop wire has repeatedly failed from pavement movement, water intrusion, or construction damage.

Technician Note
The OVS-01GT is a practical solution when the customer wants vehicle detection without cutting a loop into the driveway. It can save labor on finished concrete, asphalt, pavers, and retrofit jobs where loop wire has failed. The key is proper mounting and aiming. If the sensor is mounted too low, too high, too far from the vehicle path, or pointed into the wrong area, detection can be unreliable.
For gate operators, confirm whether the sensor is being used for open activation, presence, reverse, hold-open, free-exit, or another input function. Those inputs are not always the same. Wiring the output to the wrong terminal can cause the gate to behave incorrectly.
Before Ordering, Confirm
- Confirm the needed model is Optex OVS-01GT.
- Confirm the installation requires above-ground vehicle detection instead of a buried loop.
- Confirm the operator has a compatible low-voltage input for the intended function.
- Confirm the sensor can be mounted near the vehicle path with a clear detection area.
- Confirm the detection distance is within the practical range of the sensor.
- Confirm whether the application is for activation, presence, hold-open, reverse, free-exit, or another approved function.
- Confirm the site does not require a monitored safety device for the function being replaced.
- Confirm pedestrians, shopping carts, motorcycles, bicycles, animals, or cross traffic will not create unwanted triggers for the application.
- Confirm there is a suitable power source and wiring path to the operator or control device.
- Confirm mounting hardware, bracket, instructions, and power supply are included or available separately.
- Confirm the sensor can be protected from direct impact, vandalism, and vehicle strikes.
- Confirm the full gate system still has the required photo eyes, safety edges, warning signs, and entrapment protection.
Installation and Setup Notes
Mount the OVS-01GT in a location where it can view the intended vehicle detection area without being blocked by posts, walls, gate frames, parked vehicles, landscaping, or metal structures. Follow the current Optex manual for mounting height, aiming, wiring, menu settings, calibration, and testing.
After installation, test the sensor with the smallest and largest vehicles expected at the site. Also test pedestrian movement, motorcycles, bicycles, and cross traffic if those conditions exist near the gate. Adjust sensitivity and human-cancel settings as needed for the site.
Professional Advisory
Vehicle detection sensors should be installed and tested by a qualified gate or access-control technician when they are connected to automatic gate operators, barrier arms, industrial doors, or controlled access points. The technician should verify the input function, wiring, power, detection area, and safety-device requirements before the system is returned to service.
Do not use the OVS-01GT to bypass monitored photo eyes, safety edges, entrapment protection, fire access, emergency release, or other required safety equipment. A vehicle presence sensor may help the gate respond to vehicles, but it does not replace the safety devices required to protect people, vehicles, and property.
