Linear 2500-1928-PROBE, Probe Detector 50Ft Lead
The Linear 2500-1928-PROBE is tied to the 50 ft lead vehicle probe detector setup used in Linear / OSCO gate automation applications. It is commonly searched when the buried probe, lead, or probe-related portion of a 2500-1928 system needs replacement.
Probe-style vehicle detection can be a clean option for driveway exit or vehicle presence detection because it does not require a saw-cut loop in the pavement. The probe must be installed in the proper location and connected to a compatible controller input to provide reliable detection.
Before replacing the probe, confirm whether the detector electronics, power supply, wiring route, or operator input is causing the issue. Probe detector problems can come from damaged underground cable, incorrect burial location, poor splices, or a mismatched detector voltage.

Technician Note
A buried probe that has been cut, crushed, or water damaged should be replaced as a proper assembly. Field splices in wet or underground areas can create intermittent detection problems.
Before Ordering
- Confirm the existing detector family is 2500-1928.
- Confirm the job needs the 50 ft lead version, not 150 ft.
- Check whether the detector module is also damaged.
- Do not use this as a reversing safety sensor.
- Verify the probe location and burial method before reinstalling.
Professional Advisory
For buried detector repairs, use a qualified gate technician if underground cable routing, pavement work, or controller wiring is uncertain.
Product Q&A
Is 2500-1928-PROBE the same as the complete 2500-1928 detector?
It is related to the 2500-1928 probe detector family, but verify whether your job requires the probe/lead portion or a complete detector setup.
What lead length does this version use?
This version is associated with a 50 ft lead.
Can I extend the probe cable?
Cable changes can affect performance. Follow the detector instructions and use proper buried-rated wiring practices if extension is allowed.
Will this open a gate automatically?
When installed with a compatible detector input, it can be used for vehicle detection functions such as free exit or presence.
Does this meet UL 325 safety requirements by itself?
No. It is not a monitored entrapment-protection device.
