Product Overview
The BASE LMH6-11 harness is a service and installation part for 11-pin box-style loop detectors. In the field it is useful when a gate or parking system needs an external detector connection but the cabinet does not already have a usable detector socket. The harness gives the technician a practical way to land power, loop input, and relay output conductors from a compatible detector without trying to modify the detector itself. Because 11-pin detectors may use similar looking connectors with different voltage or relay functions, the harness should always be wired from the detector pin label and the operator wiring diagram. This part is commonly associated with access-control gates, barrier arms, overhead doors, parking systems, and free-exit loop installations where a separate detector box is mounted inside or near the operator cabinet.
Compatible With
This item is commonly used with the following applications when the voltage, wiring, relay function, and site configuration match:
- box-style 11-pin inductive loop vehicle detectors that require a remote harness or socket lead
- BASE LD-100, LD-1150, LD-1150S, LD-1250, LD-1250S, LD-1500, LD-200, and similar 11-pin detector families when the pinout matches
- gate operators, barrier gate cabinets, parking controllers, access-control panels, and detector enclosures that use hardwired external detector connections
- exit, safety, reverse, shadow, arming, presence, and counting loop installations that use an 11-pin plug-in detector

Technician Note
This harness should be treated as a wiring interface, not as a universal adapter. The detector pinout and operator control terminals still determine whether the installation is correct.
Before Ordering
- Confirm the loop detector uses an 11-pin box-style connector.
- Match every conductor to the detector pin assignment and operator wiring diagram.
- Verify detector power voltage before energizing the circuit.
- Confirm whether the gate operator expects normally open or normally closed relay output.
- Use a qualified technician for line-voltage or unclear control-circuit wiring.
Professional Advisory
Loop detector wiring can involve gate operator control circuits and, on some models, line voltage. If the power source, relay behavior, or safety function is unclear, have the system checked by a qualified gate or access-control technician.
Product Q&A
Is the LMH6-11 a vehicle detector?
No. The LMH6-11 is the connecting harness for compatible 11-pin loop detectors. The detector module and roadway loop are separate items.
Which detectors can use this harness?
It may be used with many box-style 11-pin inductive loop detectors, including common BASE LD-series detectors, when the detector pinout and the operator wiring match.
Can this harness be used for an exit loop or safety loop?
Yes, the harness can be part of either type of installation if the connected detector and gate operator are wired for that function.
What should be checked before wiring the harness?
Confirm the detector pin assignment, operator input terminals, relay common, normally open or normally closed contact, and the required power voltage before applying power.
Does the harness include loop wire?
No. Loop wire, loop lead-in cable, and the detector module are separate from this harness.
