LPCB36 وLPCB40 كلاهما محولات صور كاميرا للتركيب العلوي/السفلي، وليسا محولات خرج خط صوتي. قارن أبعادهما وحدد أيهما يناسب تركيب كاميرا القوارب لديك.
Quick answer
Choose the LPCB36 when you have a longer or deeper mounting area and want the larger 250 mm frame; choose the LPCB40 when space is tight and the shorter 197 mm frame fits better. Both are camera image up/down adapters, so neither replaces an audio line output converter for adding amplifiers.
What these adapters actually do
The LPCB36 and LPCB40 are listed as camera image up/down adjustment accessories. They let you flip or orient the camera image to match how the camera is mounted, which matters on boats where a camera may be installed upside down or at an angle.
They are not audio line output converters. If your goal is to feed a marine amplifier from a factory head unit, you need a different product, such as the LPC35 line output converter covered in our separate wiring guide. Mixing up the two categories is the most common buying mistake here.
Size is the real deciding factor
The LPCB36 measures 9.84 in × 0.94 in × 0.87 in (250 mm × 24 mm × 22 mm). The LPCB40 measures 7.756 in × 0.88 in × 0.88 in (197 mm × 22 mm × 22 mm). Both are slim, but the LPCB36 is about 53 mm longer.
On a crowded dash, helm panel, or camera housing, that extra length can be the difference between a clean fit and a bundle of cable you have to tuck away. Measure the space behind your camera before ordering, not just the visible face.
Price and catalog value
At catalog prices, the LPCB36 is listed at USD 26.43 against a comparison price of USD 37.23, while the LPCB40 is listed at USD 15.60 against a comparison price of USD 26.00. The LPCB40 is the lower-cost option, but the difference is small enough that fit should drive the decision rather than price alone.
What the catalog does not tell you
The supplied records do not list compatible camera models, connector types, or whether either adapter includes mounting hardware. Check those details against your existing camera before purchase. If your camera uses a different orientation method, neither adapter may be the right fix.
Decision rules for choosing between LPCB36 and LPCB40
- If you need audio line conversion: Stop here. Neither LPCB36 nor LPCB40 is an audio line output converter. Look at a dedicated LOC such as the LPC35 instead. Confirm the product category before comparing models.
- If your mounting depth is 250 mm or more: Choose the LPCB36. Its 250 mm length fits without forcing, and the extra length can make cable routing easier.
- If your mounting depth is under 250 mm: Choose the LPCB40. At 197 mm it is the shorter option and avoids cramming the adapter into a tight space. Measure the space behind the camera, not the camera face.
- If price is the tiebreaker: The LPCB40 is listed lower, but only pick it if the shorter frame fits your install. Do not downsize just to save a few dollars if the LPCB36 fits better.
- If you are unsure about camera compatibility: Check your camera's connector and orientation method against the adapter before ordering. The catalog does not list compatible models. Compatibility is not guaranteed by size alone.
Product facts at a glance
- LPCB36: Camera image up/down adjustment in a 9.84 in × 0.94 in × 0.87 in (250 mm × 24 mm × 22 mm) frame. The longer frame gives more room to route and secure the adapter in deeper mounting spaces.
LPCB36 - LPCB40: Camera image up/down adjustment in a 7.756 in × 0.88 in × 0.88 in (197 mm × 22 mm × 22 mm) frame. The shorter body suits tight helm or camera housings where the LPCB36 would be too long.
LPCB40
Who should choose which
Best for
- Boat owners with a camera mounted upside down or at an angle who need image up/down correction
- Installers with a measured mounting depth of 250 mm or more who want the longer LPCB36 frame
- Tight helm or camera housings where the shorter 197 mm LPCB40 frame is the only one that fits
Not for
- Anyone trying to add an amplifier to a factory marine head unit; you need an audio line output converter instead
- Cameras that do not support image orientation adjustment through an adapter
- Installations where connector compatibility has not been confirmed against the catalog
