Plug and Socket

I’m putting an STC 1000 controller in an enclosure and will be using IEC plugs and sockets for the power in and heating out elements. I would also like to use a small plug and socket for the temperature probe, any suggestions on a suitable type? I’m thinking of the small barrel type often used on small chargers. TIA and any links would be appreciated.

I've used a 3.5mm jack for one.

A bit more secure than the power leads & no change of accidentally connecting a power supply....

P.S. The flaming thing beeps if the probe isn't plugged in which is a PITA as I would like to use the box without it most of the time, I've just realised I could wire a fixed resistor across the jack socket that's switched out when I plug in the probe.

I did think of a 3.5 (or even a 2.5) but I’m not that keen on them. I’ll have a look at what’s on offer though it may be a suitable option.

Why not a GX16 type plug and socket. Often used for microphones and ham and CB transceivers.

I've just finished putting my Electronic Leadscrew in a box. I used Bulgin Buccaneer connectors, which are secure and expensive, for the steppers. For the sensor I found locking jack sockets at CPC, which are cheap and work very well. You can also get locking IEC plugs which work with a standard kettle socket for about a fiver, including 13A plug.

Hi,

For any sensors or transducers I always use XLR connectors (Microphone Type) as they are so versatile with up to 8 pins and with the correct screened cable are very resistant to RF generated by motors etc. Fully sealed types are available but they are very expensive compared to the standard type which are reasonably cheap.

You have to solder in the cables and that can be fiddly but take care and all will work well. I have a machine that has been in daily use for about seven years and I have had no problems with these connectors.

Jack sockets will work OK if you get the gold plated sockets and plugs. What I would use would be gold plated phono plugs.
