CO Miniature Housings LDG-A Models LDG-A-12 ... max. 12 connections LDG-A-14 ... max. 14 connections LDG-A-16 ... max. 16 connections LDG-A-320 ... max. 30 connections General The LDG-A series of miniature housings are fully-insulated housings to the specifications of the machinery and auto- mobile industries, with terminals protected against acci- dental contact in accordance with VDE 0100 Part 750, VDE 0160 Part 100 and VBG 4. Designed to be particularly easy to install, these housings facilitate extremely rational equipment assembly with opti- mal utilization of space. @ Connections between the circuit boards and the ter- minals by means of solderable circuit-board connec- ting pins, so that no wiring connections are needed. @ The connecting pins are suitable for automatic solde- ring processes. @ Blind plugs close off any unused terminal ducts. @ The flat cover is easily removed and can be readily drilled or otherwise adapted to requirements. Captive, self-locking terminal screws that are highly resistant to loosening through vibration. Large wiring entry channels and guidance for screwdrivers. @ Equippment can be completely assembled before being built into the housing. @ Structured surface and attractive design. @ Easy to assemble and simple to dismantle should ser- vicing be necessary. @ Creepage and air distances to VDE 0110 Group C, FARNELL COD Technical Data M4p-7383 Description LDG-A-12 LDG-A-14 | LDG-A-16 LDG-A-30 Protection Housing IP 40 Terminals IP 20 Housing base Polycarbonate (30% GFR), RAL 7032, UL 94 V-1 Terminal housing, cover and blind plugs Polycarbonate, UL 94 V-2 Material sheet steel, tinned Terminals| Wire cross section max. 2,5 mm? max. 4mm?
