RCF is an Italian audio products manufacturer founded in 1949 in Reggio Emilia, [1] [2] Italy. The first products sold were microphones and electroacoustic transducers (loudspeakers). In the late ’60s, concert sound was going electric, and many loudspeaker pioneers were searching for high-powered devices to use in their designs.
The flat parallel plug blades are polarized to prevent the hot and the neutral connections from being reversed. In addition, many versions have a molded obstruction bump on top of the adapter, to block the grounding prong and thus physically prevent forcible insertion of a 3-prong plug in the wrong orientation.
A thin quad flat pack (TQFP) provides the same benefits as the metric QFP, but is thinner. Regular QFP are 2.0 to 3.8 mm thick depending on size. TQFP packages range from 32 pins with a 0.8 mm lead pitch, in a package 5 mm by 5 mm by 1 mm thick, to 256 pins, 28 mm square, 1.4 mm thick and a lead pitch of 0.4 mm. [2]
12 Volt 7-pin trailer connector ISO 7638-2 for ABS and EBS (Towing vehicle side) Physical design according to standard ISO 7638-2. [4] [6] [7] This connector is intended to be used for 12V ABS and EBS on heavy duty trailers. Identified by key tab on outer ring between pin 3 and 4. #
Variety of loose pogo pins and pogo pins in 3-pin assembly holders and with Pick and Place caps Sectional drawing of a pogo pin, showing the plunger, barrel, and spring. A pogo pin or spring-loaded pin is a type of electrical connector mechanism with spring plungers that is used in many modern electronic applications and in the electronics testing industry. [1]
AS/NZS 3112 compliant plugs have two flat pins forming an inverted V-shape plus a vertical earthing pin. The flat blades measure 6.35 by 1.6 mm (1 ⁄ 4 by 1 ⁄ 16 in) with the active (line) and neutral pins 17.35 mm (11 ⁄ 16 in) long set 30° to the vertical and the vertical earth pin being 20 mm (0.787 in) in length.

The former Soviet Union and Eastern bloc countries used similar packages, but with a metric pin-to-pin spacing of 2.5 mm rather than 0.1 inches (2.54 mm). The number of leads is always even. For 0.3 inch spacing, typical lead counts are 8, 14, 16, and 20; less common are 4, 6, 18, 24, and 28 lead counts.
Multicon [1] Feder and Multicon WeSt (Welt Standard) connectors are precursors to ISO 11446 in a design that is intended to be compatible with ISO 1724.This means that if a towing vehicle has an outlet of this type it should be able to connect a trailer with a standard 7-pin or 5-pin connector according to ISO 1724, provided that the trailer coupling follows the standard and that the trailer ...
