Compare the task, mounting envelope and interface before choosing.
A wire-loop kit for vehicle presence at a controlled access lane. The detector belongs in a protected cabinet. Sealant, pavement work and cabinet power are not included.
12–24 V DC detector; dry relay output; saw-cut pavement installation
A temporary axle-event counter with a replaceable road tube. Counts are not vehicle classifications or certified speed measurements. Plan safe tube fixing and supervised installation.
Battery-powered counter; single pneumatic input; local count display; dry-weather temporary survey
A recessed magnetic presence sensor for a single defined detection zone. Check steel reinforcement, burial depth and local magnetic interference during a site trial.
9–30 V DC; wired RS-485 output; core-drilled stationary presence detection
A non-contact roadside radar head for movement sensing. Lane geometry, mounting angle and controller protocol require a site-specific check; it is not an enforcement device.
12–24 V DC; RS-485 output; above-road motion detection; dry-cabinet termination
An opposed optical pair for a defined beam-break zone. Alignment, fog, dirt and a clear line of sight matter. Do not use as a certified safety barrier.
12–24 V DC; paired transmitter and relay receiver; opposed lane-edge mounting
A thin adhesive windshield transponder with no battery or account value. Metallized glass can block reading; confirm the permitted mounting zone and reader protocol before fulfillment.
860–960 MHz passive UHF hardware; compatible reader and operator acceptance required
A rigid windshield unit supplied with a removable mounting cradle. It is hardware only: reader frequency alone does not prove operator compatibility or enrollment.
Battery-assisted 915 MHz hardware; internal sealed battery; reader-specific protocol confirmation
A narrow exterior transponder bar for applications where windshield placement is unsuitable. Confirm bolt spacing, plate visibility, local mounting rules and the receiving system.
Passive UHF hardware; external metal-adjacent mount; reader and plate clearance check
A selectable windshield housing for systems that explicitly support state selection. The selector does not confer a toll discount or declare occupancy to an unsupported operator.
Battery-assisted 915 MHz hardware; three-position selector; application-specific reader support
A powered bolt-on transponder for a matched heavy-vehicle installation. Confirm the exact radio protocol, power protection and cable routing before purchasing; no antenna or network approval is implied.
12–24 V DC powered 5.8 GHz hardware; vehicle exterior mount; matched reader required
