Default splicing a transducer cable?

If a transducer cable is cut, is there any way to splice it, or is it now junk?

If you can splice it, what connection would be used?

Bamaboy: Yes you can easily splice a cut transducer cable. If I were doing it I would use high quality, marine butt splices, a commercial grade crimper and adhesive lined heat shrink tubing - I would avoid using automotive splices. Using the adhesive lined heat shrink tubing, available at any good electronics supply house, will insure a waterproof connection.

Why connectors and not solder?

butt connectors and splicing a transducer cable should not be uttered in the same sentence, no matter how miraculously good the butt connector claims to be. When trying to re-attach a compromised transducer cable there are two types of connections, soldered and wrong. solder and heatshrink each wire individually, then heatshrink the entire area where the joints where done for support. Assuming the sounder was not on and transmitting when the cable originall got cut (an conductors could have shorted, damaging the sounder and/or the transducer element), and the original cable length has not been radically altered, you should be fine.

hi,
simply the t/d cable have usually from 3 (black/white/ copper = +/-/ shield t/d, bigger) to 5 wires ( + 2 smallest for temp sensor) you have only to cut to decreasing length every wire , to knit to pond ( flux cores solder wire) and to use a thermo retracting (shrinking ) girdle to splice every single solder wire and one more thermo retracting that joins them all . The biggest unique thermo retracting may have thermo glue into so rectractling by thermo ( not a flame but worm air ) the glue seals all .
100% guaranteed impermeable treatment for several years

I have had much better luck over the years with crimped connectors over solder connectors. Solder works great on circuit boards and jacks and plugs like it was designed. Crimp connectors were designed to connect wires. Solder connections on wires that are subject to a lot of vibrations or movement are more likely to break because the connection is so brittle. Like it was stated perfectly above, using marine adhesive lined butt connectors of the correct size, then covered again with the correct size adhesive lined shrink tubing will outlast the transducer.

The best crimpers I have ever used are the old Thomas and Betts, or the copy that Ideal makes. I like it better than the rachets. I have made thousands and thousands of crimps over the years and was Navy Micro Miniature trained, and I like the crimps over solder for connecting wires in almost every situation. The old western union spice should have died with the telegraph machine.....!

If a solder connection between two wires breaks the problem is the workmanship not the use of soldering for connecting the wires.

Twist the wires together before soldering, and be sure to apply enough heat to the solder.

i'VE made a living for the last 20yrs as a lead cable splicer,I ve worked on all types of cables for high voltage and low voltage applications, soldering and crimping both, there is no data that says a solderd connector is any more reliable then a properly crimpped connector. I personally would crimp it due to the small size,its not as easy as one would think to properly clean and solder a small stranded cable/wire and have a tight as conection as a crimped one in comparasion,if all strands are not tinned it could lead to "hot spots". just take your time eather way.I do agree with using heat shrink tubing to insulate

I've used a furuno junction box before that works well to keep out water. Just about $20 if I remember correctly. All it has inside is a european connector like this, inside a waterproof plastic box

as long as its air tight too to keep out the salt air thus causing corrosion it should work fine.
