Diablo Controls DSP-50 Mini-Loop Probe Kit, 100 Ft Lead
The DSP-50-Kit-100 combines the older DSP-50 plug-in detector platform with a Diablo mini-loop style buried vehicle sensor and 100 ft of lead cable. Instead of using a large multi-turn saw-cut loop, the mini-loop/probe is installed as a smaller point detector below the roadway surface. This can reduce cutting work and can help avoid some crosstalk problems in tight installations, but it also changes the detection pattern. A mini-loop/probe is typically used for free-exit or point vehicle detection, not as a broad presence field for all safety situations. Correct application depends on the driveway layout, sensor placement, operator input, and detector setup. If the system currently uses DSP-55 or another newer detector, do not assume this older DSP-50 kit is the right replacement without checking the original documentation.
Compatible With
- Select gate, parking, and access-control systems using compatible DSP-50 plug-in detector wiring
- Diablo mini-loop/probe installations requiring a 100 ft lead version
- Free-exit or point-detection applications where mini-loop sensing is appropriate
- Legacy DSP-50 mini-loop systems when current replacement direction is verified
- Applications where a smaller buried sensor is preferred over a conventional full-size loop and safety requirements allow it

Technician Note
Match the detector to the original part number, voltage, connector style, loop function, and output behavior. If a detector still shows a loop fault after replacement, test the loop and lead-in wiring before assuming the new detector is defective.
Before Ordering Checklist
- Confirm the exact Diablo Controls part number on the old detector or supplier record
- Verify the control voltage available at the detector connection
- Confirm the connector style, terminal layout, or plug-in board port
- Check whether the loop function is exit, safety, shadow, arming, hold-open, or presence
- Inspect loop resistance, lead-in splices, and water intrusion if the original detector failed
Professional Advisory
Loop detectors are vehicle-detection accessories and must be installed as part of a code-compliant gate or access-control system. Do not bypass required monitored photo eyes, monitored safety edges, or other entrapment-protection devices. For high-voltage wiring, unsafe gate movement, or repeated loop faults, use a qualified gate technician.
Important Ordering Warnings
Similar Diablo detector numbers may not be interchangeable. Pay close attention to fail-safe versus fail-secure operation, low-voltage versus line-voltage power, terminal-block versus plug-in construction, and standard loop versus mini-loop/probe operation.
Product Questions and Answers
What is included in DSP-50-Kit-100?
It is commonly referenced as a DSP-50 detector kit with a Diablo mini-loop/probe sensor and 100 ft lead.
Is the mini-loop the same as a standard driveway loop?
No. The mini-loop/probe is a smaller point-detection sensor and does not create the same detection area as a full-size inductive loop.
Can this kit be used for a free-exit application?
Yes, it is commonly associated with free-exit or point-detection installations when the gate operator input and site layout support that use.
Has this kit been replaced by newer Diablo products?
Many references point older DSP-50 products toward DSP-55 replacement direction, so current availability and compatibility should be verified.
What lead length should be ordered?
Match the lead length to the installation layout. This row is for the 100 ft version; 75 ft kits and other detector families may also exist.
