2-Pin Parking Sensor / Reversing Radar Connector – OEM 7283-8720-30 / 7182-8720-30
Direct OEM-specification replacement for the 2-pin connector used on parking distance control (PDC) sensors and reversing radar probes. Cross-references Sumitomo part numbers 7283-8720-30 (female/socket side) and 7182-8720-30 (male/plug side). Available bare or with 15cm pre-wired leads.
Parking sensor connectors are mounted in the rear bumper, directly exposed to road spray, pressure washing, and stone impacts. The 2-pin Sumitomo connector's small housing is particularly vulnerable to locking tab fracture from bumper flex during minor impacts. A partially disengaged or corroded PDC sensor connector causes the parking system to log the sensor as "not detected" — producing continuous beeping or a PDC system fault warning on the instrument cluster. The connector is the most common cause of single-sensor PDC faults before the sensor itself is replaced.

Q: My parking sensor beeps continuously when reversing — is it the connector?
A: Continuous beeping from a single PDC sensor is a classic symptom of a disconnected or corroded sensor connector. The PDC module interprets a missing signal as a permanent obstacle. Inspect the 2-pin connector at the affected sensor before replacing the sensor — the connector is the most common failure point and costs a fraction of a new sensor.
Q: What fault codes does a failed PDC connector cause?
A: Depending on the vehicle platform, a failed 2-pin PDC sensor connector typically triggers codes such as U0415 (invalid data from anti-lock brake system), sensor-specific PDC fault codes, or manufacturer-specific codes (e.g., Honda B10D4, Toyota C1A00-series). The fault is usually stored as "sensor not detected" or "sensor circuit open."
Q: Is this connector waterproof?
A: Yes. The PA66 nylon housing includes a rubber wire seal at the cable entry and a face seal at the mating interface, making it suitable for rear bumper and underbody environments exposed to road spray and pressure washing.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
Q: Can I use this on front parking sensors as well?
A: Yes, provided the front PDC sensors on your vehicle use the same Sumitomo 2-pin housing (7283-8720-30 / 7182-8720-30). Verify by checking the OEM part number on the existing connector before ordering.
Q: What wire gauge do the pre-wired leads use?
A: The 15cm pre-wired variants use 22AWG wire, which is the standard gauge for PDC sensor signal and ground circuits in Honda, Toyota, Nissan, and Mazda applications.
