Erni fully-insulated terminal housings meet requirements falling between single card enclosures and 19" racks.
The range of smaller LDG-A housings provide a facility for insertion of two longitudinally-aligned boards and on board as cross connection and as location for control and display elements. The housing bases can be screwed onto mounting panels and have a snap-on fixing to standard DIN 46277 rails and DIN EN 50022 rack assemblies. They afford IP40/IP20 protection with/without mounted terminals and can be used over an ambient temperature range of -40 to +110°C. Units have a standard height of 110 mm, length of 75 mm and come in widths of 22,5, 45, 55, 99,7, 150, and 225 mm with respectively 12, 14, 16, 30, 46, and 70 terminals.
LDG-A expansion elements include an aluminium covering for the housing base that serves as a mounting and guide element for PCBs and output plug; frame insert; plug insert with integrated 17 pole multipoint connector; and blanking insert for complete covering of the base housing. Depending on assembly, the frame insert offers a maximum mounting area for components or additional fitting of a transverse board.
The larger LDG-D Series of housings are available in three sizes with 6, 10, and 20 terminals with standard length of 70 mm, width of 25, 50, and 100 mm and heights of 130/100 mm. Almost all direct connectors such as DIN 41612, 41613, 41617 or 41651 can be fitted, as well as other families, using mounting bars or suitably preassembled units.
A further series of compact LDG-M4 housing constructed to DIN EN 50041 provide insulated cuboid enclosures for proximity switches and momentary-contact limit switches. The can be screwed down or fitted with an adapter for rail mounting. Overall dimensions are 94 x 42 x 42,5mm.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
