Of course. The gender complement is this guy: http://www.alliedelec.com/lumberg-automation-hirschmann-rsc-4-7/70050935/ They're not cheap at about $20/pr, but they are both IP67 and also field-serviceable (internal screw terminals). This is a rare combination that customers who do not want to

Colin, Thanks very much, especially for the tip on Lumberg connectors. I have been wanting such for a long time. Peter On Wed, Jun 1, 2016 at 1:46 PM, Colin Reese wrote: > Something like this is suitable: > > >

Re: [Owfs-developers] Cable Length

Yes, in this case you will need to make your own 8P8C --> three conductor pigtail and butt-splice or screw-terminals on a piece of protoboard. No biggie. C On 6/1/2016 1:44 PM, Peter Hollenbeck wrote: > Am using a LinkUSB connected to a Raspberry Pi. > Not 1wire-smart, > Peter > > On Wed, Jun

Re: [Owfs-developers] Cable Length

There is plenty of industrial quality cable that fits these purposes. Furthermore, it's typically stranded, whereas most varieties of spooled Cat5/6 will be solid core, which is not as durable and more difficult to terminate in, say, terminal blocks -- especially spring-loaded. I use this

Any thoughts on outdoor use? I will look online but thought I would ask. Peter On Wed, Jun 1, 2016 at 12:14 PM, Colin Reese wrote: > Don't use Cat5. Just get some good 22/3 or 22/4. It's cheap and easy to > find. > > C > > > On 6/1/2016 12:07 PM, Peter Hollenbeck wrote:

Re: [Owfs-developers] Cable Length

Don't use Cat5. Just get some good 22/3 or 22/4. It's cheap and easy to find. C On 6/1/2016 12:07 PM, Peter Hollenbeck wrote: > My DS18B20 works over 34 feet of Cat5e but not over 160 feet. > Resistance for the 160 foot wire is 4.7 ohms, 0.29 ohms per foot. > Resistance for the 34 foot wire is

[Owfs-developers] Cable Length

My DS18B20 works over 34 feet of Cat5e but not over 160 feet. Resistance for the 160 foot wire is 4.7 ohms, 0.29 ohms per foot. Resistance for the 34 foot wire is 0.9 ohms, 0.26 ohms per foot. Both lengths of cable are from the same 200 foot length. Is my 160 foot cable too long or might I have
