When it comes to automatic gates for vehicles, safety and compliance are of the utmost importance. That’s why it’s essential that installers, facility managers, and other professionals use efficient solutions that meet the UL325 — the safety standard for automatic door and gate operation. And a key element of any automated system is the presence detection sensor. Here, we’ll explore three EMX vehicle presence detection sensors, explain what they do and their key benefits, and provide other helpful resources.
Proximity Sensor/Cushion Edge Sensor
These are used to detect objects in close proximity to an automatic gate or door without physical contact being made. This type of sensor is typically installed at the base of an automated gate or door but can also be used in other applications such as over-head doors. They are designed to detect both stationary objects as well as those that are moving which makes them ideal for applications where automated gates will be used by pedestrians or in areas with high traffic flow. The main benefit of this type of sensor is its small size which makes it easy to install in tight spaces. It also has a high level of sensitivity which helps ensure that objects are detected quickly and accurately regardless of size or speed. Additionally, this type of sensor is usually very cost effective making it an attractive option for budget-conscious projects.
EMX Vehicle Presence Detection Sensors
EMX Universal UL325 Retroreflective Photo Eye | EMX-IRB-RET
The IRB-RET is a monitored, weather-proof retroreflective photo eye solution providing entrapment protection for automatic gates and doors. Retroreflective configuration eliminates the need for a separate transmitter and the associated wiring across a roadway to reduce installation costs. The IRB-RET photo eye unit is UL325-2018 compliant and housed in a rugged NEMA 4X enclosure suitable for indoor and outdoor use.
Includes
- Retroreflective photo eye
- Steel mounting bracket
- Hardware
- White plastic reflector 3″ diameter reflector-o-ex
Features
- Type B1, non-contact sensor
- UL 325-2018 compliant
- Operating range up to 60 ft. (18.3 m)
- NEMA 4X enclosure
- Sensitivity adjustment: potentiometer
EMX Wireless Edge Link | EMX-WEL-200K
The WEL-200 provides a complete wireless solution for interfacing sensing edges with gate and door operators. The WEL-200 system eliminates the need to wire between the safety edge and operator control box while ensuring compliance with 2018 UL325 monitoring standards. The Wireless Edge Link operates at up to 200ft. (line of sight) between transmitter and receiver. The receiver connects with up to four transmitters, with separate relay and pulse outputs for open and close edge functionality. The WEL-200 is housed in rugged, watertight, NEMA 4X enclosures.
Includes
- Wireless Edge Link Kit
- 1 Transmitter
- 1 Reciever
Features
- UL325-2018 compliant
- NC, 10K, and pulse monitoring
- Up to 200 ft. operating range (line of sight)
- Connect up to 4 safety edge transmitters
- NEMA 4X enclosure
EMX LRS Sensor Kit - Flat Pack Sensor with 100 ft. Lead and LRS Controller | EMX-LRS-FP-100-K
The Loop Replacement System (LRS) features advanced 3-axis, magnetoresistive sensing technology. The sensor measures Earth’s magnetic field and responds to disturbances caused by ferrous objects. Three sensing elements provide magnetic field measurement in the X, Y, and Z axes, improving detection sensitivity. The LRS’s exciting new technology provides a high-sensitivity, compact, and cost-effective solution for reliable vehicle detection.
The small size of the LRS allows for easy installation in pavement (below grade) with a single saw cut. It provides cost savings on labor and materials when compared to the multiple cuts and corner reliefs required for the installation of inductive loops. The rugged sensor is also suitable for above grade installations, making it ideal for use in confined areas or hidden in non-ferrous architectural components for security purposes.
Applications
- Automatic gates and doors
- Drive-thru windows
- Car washes
- Parking and traffic monitoring
- Loading docks
Features
- Three-dimensional presence detection of vehicles
- Select X, Y, Z-axis independently
- Stand-alone sensor
- The sensor stores ambient background and settings in non-volatile memory
- Remote control module for programming and additional relay contact output
- ULTRAMETER™ displays optimum sensitivity setting/crosstalk interference
- DETECT-ON-STOP™ allows detection only when a vehicle has come to a complete stop
- Optional Logic Interface for extended detection
Vehicle Presence Detection Sensors with EMX
Vehicle presence detection sensors play a key role when it comes time installing automatic gates compliant with UL325 standards—and beyond just safety requirements too! By understanding the differences between different types of sensors—their strengths/weaknesses along with their various uses—installers can confidently select one that meets their specific needs while avoiding unnecessary damage and repair costs associated with improper installation.
