The EMX PROBE-150 is a direct burial magnetic vehicle sensing probe designed for use with the EMX CarSense 101 vehicle motion detector system. Manufacturer part number EMX-1815-1 identifies the probe configuration with approximately 150 ft of shielded direct burial lead-in cable.
This is a replacement or installation probe only. It does not include the CarSense 101 control module and cannot provide a gate activation output by itself. The probe must be connected to a compatible CarSense 101 controller, which processes changes in the magnetic field and provides the appropriate relay output to compatible gate operators, parking barriers, overhead doors, security systems, or other control equipment.
Confirm the exact controller model before ordering. The PROBE-150 should not be assumed compatible with VMD202, LRS, inductive loop detector, or other EMX vehicle detection systems simply because those products also use magnetic or vehicle sensing technology.
The CarSense 101 probe is a passive magnetic sensor. It responds to changes in the Earth's magnetic field caused by moving ferrous metal, such as a vehicle passing through the sensing area.
The probe sends this change to the CarSense 101 controller. The controller handles sensitivity adjustment, off-delay timing, indication, and the DPDT relay output used by the connected gate, door, barrier, alarm, or access-control system.
The CarSense 101 is designed primarily as a vehicle motion detector. It should not be selected when the application requires reliable continuous presence detection of a stopped vehicle.
This distinction is especially important when choosing a detector for automatic gate applications. Free-exit activation and vehicle movement detection are different functions from monitored entrapment protection or dependable vehicle presence detection.

The PROBE-150 is only the buried sensing component. A complete CarSense 101 installation also requires the compatible CS-101 control module and appropriate wiring and mounting components.
CarSense probes have been offered with different factory lead lengths. The lead length should be selected according to the distance between the buried probe and the protected controller location.
Do not order by probe appearance alone. Confirm the required lead length and existing CarSense controller before purchasing.
The probe must remain completely motionless after installation. Movement or vibration can change the magnetic field seen by the probe and create false vehicle detections.
For soil installations, EMX documentation calls for burying the probe parallel to the direction of traffic and at least approximately 6 inches below grade. Installations beneath asphalt or concrete may use a different depth and method according to the current CarSense installation instructions.
Power wiring, transformers, motors, and other sources of electromagnetic interference can cause false activation. Do not route the probe lead in the same conduit as electrical power wiring.
The probe cable is shielded and intended for direct burial, but it should still be protected from physical damage to the outer insulation during installation.
The CarSense probe responds to moving ferrous metal, not specifically to automobiles. A moving steel gate, barrier counterweight, machinery, metal door, or other large ferrous object near the probe may create a detection signal.
Choose the probe location so normal gate movement and other nearby equipment do not enter the probe's sensing field.
The CarSense 101 controller, LD-11 or LD-11B socket, HAR-11 harness, conduit, junction hardware, gate operator, power supply, and other installation equipment are not automatically included.
If an existing CarSense 101 installation begins false-triggering, do not automatically replace the probe. Check for probe movement, damaged lead insulation, water-damaged connections, electrical interference, nearby moving steel, controller sensitivity, noisy power, and grounding or shielding issues.
If the controller operates normally but does not respond to vehicles, inspect the probe cable and connections before replacing components. Damage to buried lead wire is a common service concern and should be ruled out.
Install the probe so it remains completely stationary and follow current EMX instructions for orientation, burial depth, cable routing, and connection to the CarSense controller. Do not install the probe lead in conduit containing power wiring.
Before excavating, trenching, or cutting pavement, locate underground utilities, electrical conductors, irrigation, reinforcing steel, and other buried services. When existing wiring or controller connections cannot be positively identified, installation should be performed by a qualified gate or access-control technician.
The PROBE-150 is part of a vehicle motion detection system. It is commonly used for free-exit and vehicle activation functions but is not a monitored entrapment-protection device.
Do not use the CarSense probe to bypass required photo eyes, monitored safety edges, obstruction protection, emergency access, fire access, or other required gate operator safety circuits.
The PROBE-150 is a direct burial magnetic vehicle sensing probe for the EMX CarSense 101 vehicle motion detector system. It includes approximately 150 ft of lead and requires a compatible CarSense 101 controller.
No. PROBE-150 is the sensing probe and attached lead only. The compatible CarSense 101 control module, socket or harness, and other installation components are separate unless specifically included in another package.
The primary difference is lead length. PROBE-100 uses approximately 100 ft of lead, while PROBE-150 uses approximately 150 ft. Confirm the distance to the controller location before ordering.
The CarSense 101 is primarily a vehicle motion detector rather than a continuous presence detector. Do not rely on it to maintain dependable detection of a stopped vehicle when the application specifically requires presence detection.
No. The sensing probe is designed to work with a compatible CarSense 101 control module. The controller processes the probe signal and provides the relay output used by compatible gate, door, barrier, or access-control equipment.
Possible causes include movement of the buried probe, nearby moving ferrous metal, damaged lead wire, power-line interference, noisy controller power, excessive sensitivity, or routing the sensor cable near electrical wiring. Inspect the installation before replacing the probe.
Do not assume compatibility. PROBE-150 is associated with the CarSense 101 system. VMD202 and LRS products use different detector designs and should not be substituted without exact manufacturer documentation confirming compatibility.
No. PROBE-150 is part of a vehicle motion detection system and must not replace required monitored photo eyes, safety edges, entrapment protection, or other gate operator safety devices.
