6.3mm (1/4 inch) Mono Plug, Black Shell, Gold Plated OD:7.5MM
This is a high quality 1/4" mono plug for use with bulk microphone or instrument cabling. It features a gold plated connector tip, a metal connector body, and a strain relief spring type jacket at the base of the connector body.
PROS: Well made, durable, reliable, good looking, easy to assemble, great price.
PROS: Great value as usual from Monoprice.
CONS: Spring relief metal is a bit soft. Not very hard to tweak the spring out of shape. Interior of cover edges are sharp but this would not normally be a problem.
I have two problems with these plugs...
When soldering the cables I felt very good about the construction... It felt very solid. However after making a few cables I got a dead short on the cable tester. I was able to deduct that it was the connector's shield had made contact with the "tip" conductor in the plug and had created a dead short on my cable. I started to test impedance with a Fluke and realized it only happened as I was crimping down the wire to the strain relief... a standard operation with this plug. I saw this happen with two other plugs as well.
It was lucky I had a few other Monoprice connectors in our parts bin from a previous project. I still got the job accomplished but I'd like for such an easy to work on connector to have better results. QA needs to be improved.
The other problem stems from the wire spring that works to reduce strain on the plug itself. I have seen this several times in the field, using relatively skinny Belden BL-5000 wire. The spring likes to get inside the connector, making the possibility for a dead short when plugged into a speaker. This would only be a problem with smaller diameter wire like the Belden I am using.
The spring is fine, as it would happen with any other cable and plug combo. Monoprice SHOULD look into the other issue of crimping down the strain relief. It isn't up to par that the simple act of terminating a cable would create issues.
PROS: Connector is very easy to solder.
CONS: Had several short out after crimping down the cable relief.
