BACKGROUND:
Yes, more weird bits and pieces from Russ ... one of the recent "patients" on the operating table was a nice (but of no practical use in it's original form) fiber optic multi-strand, rack mount patch bay system. The interesting optical side of this equipment is detailed separately and this advertisement is only for the cable entry components, selected because of their "pedigree" i.e ABB and ALCO product, both well known names in the world of high quality connectors, conduit etc - particularly in high temperature or hazardous environments.
Why do I bother with these "operations"?
I don't view old equipment using the lens that if it is old or not suitable for it's original purpose, that it is destined for landfill ... far from it.
I look at all equipment from the point of view of sustainability - "perhaps I can salvage something (that is functioning) from this gear and the extracted "organs" could be repurposed in other equipment ... besides that, it is fun and sometimes I find little surprises inside those steel rack cabinets!
What is all this about sustainability Russ?
Sustainability far more than NOT burying waste material back into the earth but consciously recognising the energy expended to create the item through it's various "stages" in life, beginning with the raw materials being extracted from the earth, processed, finished and then fitted into equipment - every single step used energy which is referred to as embodied energy.
To give an approximate representation of how much energy was used in the WHOLE production process of an item, I have created what I refer to as the Ee (Embodied Energy) value, measured in Mj
The Ee value is an approximation only and usually measured in Mj.
Coming up with an Ee value is an attempt to take into account the energy used for extracting and processing of the raw materials, manufacturing of the component, distribution of the component(s) and final assembly of the component. In fact the measurement of Ee can become extremely complicated and technical, many tertiary institutions are involved in this specialised field of science.
I have used various reliable sources online to arrive at approximate Ee values, these are approximations and the sole purpose is to raise awareness of the extraordinary energy consumed in the creation of various electronic components and hardware - it may give you cause to think twice before wasting all that energy and burying it in the ground, with the possible side-effects of poisoning the environment due to leeching.
HERE is a page I have created which gives some tables and more detailed information about specific Ee values for different materials plus a link which you can use as a starting point to investigate Ee for yourself.
This advertisement covers ONLY the cable entry components which I am sure could be adapted to someone else's project or existing equipment.
Three primary components are being offered as a "family", each belongs to the others.
At the entry point is a ALCO M20 (thread) 1.5 Cable Gland which is all Black nylon.
This screws into a nice ABB Adaptalok Type SA 21mm which has a Brass body with Nickel coating at one end and Black nylon for the conduit locking system at the other.
Fitting into this Adaptalok is a short length of 21mm OD Black conduit, this conduit also has a single Black nylon conduit locking clamp to fix the position of the conduit within the rack case.
So, a bit more detail ...
CABLE ENTRY COMPONENTS (Supplied as a "kit" not separately)
As mentioned above, this offering includes ONLY these items.
a) ALCO M20x1.5 Cable Gland
Black nylon construction
I have measured the gland entry point and the results are ...
Fully open 9.75mm diameter (the gland is a rubber material and I think this could be opened more for a wider cable entry)
Fully closed 7mm diameter
Exit from this gland (where it fits into the ABB Adaptalok) is 14.5mm inside diameter
Complete nylon body is 41.5mm length
b) ABB Adaptalok M20 thread (so it mates with the cable gland above) with a two part body. The entry point for the cable gland is a Brass body with Nickel plating - it actually looks like stainless but I could not find any of these from ABB that mentioned stainless coating.
The back end of this component has the Adaptalok which interfaces between the cable gland entry and the cable conduit on the other side. It is designed for 21mm OD conduit.
Complete body length of this component is 58.85mm
When the cable gland (a) is fully screwed into this Adaptalok assembly, the complete assembly of the cable gland & Adaptalok measures 90mm in length.
c) Black conduit which is 21mm outside diameter and it fits snuggly into the Adaptalok and held in place by the twin Adaptalok "fingers" which grip the conduit within the grooves of the conduit. This conduit has factory stamped markings along it's entire length but for the life of me I cannot figure out what they say! Not much use having identification print if you cannot read it! I assume this is an ABB product as they do supply this type of conduit but other than the outer diameter, I cannot say what the characteristics may be i.e flame retardant? High temperature? This conduit comes with a single chassis mount (with bolt) securing bracket which clamps around the conduit.
Conduit is just 500mm in length
COSMETIC CONDITION:
USED
All components are clean
NO physical damage to any component
All of these components have always "lived" indoors and in fact well protected INSIDE the rack cabinet, meaning there is very little evidence of wear n tear.
