Terminal Housings are a family of enclosures that may be used to environmentallyprotect 10, 15, 20, 25 or 30 terminal blocks. Each housing includes a standard DIN rail for mounting terminal blocksalong with all grounding hardware. A sufficient amount of room is provided for making drop wire terminations while thehousing features a small, compact and visually appealing design. Housings may be ordered with or withoutterminals, pre-stubbed or without stub wiring. Rubber grommets are included at all drop wire cable entry and exit ports.
The STB module provide a connection point between an exchange-side cable pair and
a distribution pair. It incorporates a 10-point plug in module to provide continuity
and a range of other options.
Multi-Serivce terminal housings are especially functional in that up to 20 pairs may be terminated inside the enclosure while up to 200 pairs may be “looped through”, a technique that eliminates the need for an additional joint or closure in close proximity to the terminal housing.
Rugged, compact design.
Molded from high impact and UV resistant plastic.
Lightweight and cosmetically appealing.
All metal parts of non-corrosive materials
All bonding and grounding hardware included.
Rubber grommets included for all cable entry/exit ports.
Standard DIN rails included.
DIN rail doubles as an earth point.
Easy access to both sides of the terminal blocks.
Minimum twenty year life cycle tested.
Fully populated, protected or unprotected terminals are preinstalled and cable ready.
It is especially recommended for:
1. Outdoor connections where the enviromental conditions are extremely agressive.
2. Terminations where user development characteristics require future flexibility in terms of the type of protection or filtering capabilities.
