Linear 2500-1928, Probe Detector 24Ac 50Ft Memo
The Linear 2500-1928 is a 24 VAC probe-type vehicle detector commonly used with automatic gate operators and access-control equipment. The 50 ft lead makes it suitable for installations where the probe location is relatively close to the gate operator or control enclosure.
In a typical gate installation, a vehicle probe is used to detect the metal mass of a car or truck and trigger an open or hold-open command through the gate controller. This helps with exit lanes and vehicle presence detection, but it is not an entrapment-protection sensor.
Lead length and voltage are important. The 2500-1928 should not be confused with 150 ft probe versions, 24 VDC probe detectors, or loop detector modules. If the buried lead is damaged, water-intruded, or spliced incorrectly, replacing only one component may not solve the detection problem.

Technician Note
Use vehicle probes only for vehicle detection functions. A probe cannot protect pedestrians or meet monitored reversing safety requirements by itself.
Before Ordering
- Confirm the existing detector is the 24 VAC 50 ft lead version.
- Do not confuse this with 2500-1883 150 ft lead versions.
- Confirm the operator input and desired function before wiring.
- Inspect the lead route for cuts, water intrusion, or failed splices.
- Keep required photo eyes and safety edges in service.
Professional Advisory
Buried detector work and operator cabinet wiring should be performed by a qualified gate technician, especially where pavement, conduit, or unknown low-voltage wiring is involved.
Product Q&A
What is the lead length on 2500-1928?
This part is commonly listed as a 24 VAC vehicle probe detector with a 50 ft lead.
Is this the same as 2500-1883?
No. 2500-1883 is commonly listed as a 150 ft lead version, so confirm the length and part number.
Can this be used as a safety reversing device?
No. It is a vehicle detector and should not replace monitored photo eyes or sensing edges.
What is it commonly used for?
It is commonly used for vehicle presence or free-exit detection in compatible gate operator systems.
Why does voltage matter?
The detector must match the operator or control system power supply. A 24 VAC probe should not be substituted into a 24 VDC-only system without confirmation.
