Contacts

Function

Description

 

 

 

1 & 3

Zero-Position Switch

Connects to an internal single-pole single-throw normally

 

(Models A and E Plus)

open switch. Contacts are closed when the slide tray is at any

 

 

position other than zero. These leads connect only to the

 

 

switch terminals. Do not exceed a switching load of 1 A at

 

 

30 V ac.

 

 

 

4 & 5

Shutter Switch

Connects to an internal single-pole single-throw normally

 

 

closed switch. Contacts are open when a slide is in the

 

 

projector gate and the shutter is open. These leads connect

 

 

only to the switch terminals. Do not exceed a switching load

 

 

of 1 A at 30 V ac.

 

 

 

7 & 8

Low-Voltage Supply

For operating external equipment. The current is supplied by

 

 

a secondary winding on the main motor, isolated from the

 

 

line-voltage power, and is available whenever the main

 

 

projector motor is running. Supply is 25.5 V, 500 mA (1/2 A)

 

 

maximum. Contact number 8 is common (return) for the

 

 

remote-control circuit. Contact number 7 is the “hot” lead and

 

 

is fused with a slow-blowing fuse. (Replacement requires

 

 

disassembly of the projector by a qualified technician.)

 

 

 

6 & 8

Forward Tray

Connects to the forward tray-advance circuitry in the

 

 

projector. These contacts are connected internally to the

 

 

remote-control receptacle and an electrical connection made

 

 

at either receptacle will result in a forward cycle.

 

 

 

2 & 8

Reverse Tray Cycle

Connects to the reverse tray-advance circuitry in the

 

 

projector. These contacts are connected internally to the

 

 

remote-control receptacle and an electrical connection made

 

 

at either receptacle will result in a reverse cycle.

 

 

 

Shell

Plug Ground

If a plug with a conducting shell is used, it is connected to the

 

 

projector frame (chassis) through the special-application

 

 

receptacle and to earth ground through the projector's power

 

 

cable.

III specifications

The Kodak III, introduced in the mid-20th century, represents a significant evolution in the world of photography. As part of Kodak's illustrious line of cameras, it incorporated various technologies and features that aimed to enhance the photographic experience for both amateurs and professionals.

One of the main features of the Kodak III is its compactness and ease of use. Designed for portability, it allowed photographers to capture moments with minimal hassle. The camera is often lauded for its intuitive controls, making it accessible to users who may not have extensive experience in photography.

The Kodak III also introduced a robust lens system. It typically came with a fixed lens that offered sharp focus and high-quality images. The camera employed a simple yet effective shutter mechanism that ensured reliability. This ensured that users could quickly capture images without worrying about complicated settings, making it ideal for on-the-go photography.

In terms of film technology, the Kodak III utilized 620 film, which was prevalent at the time. This film format was known for producing high-quality images with excellent color saturation and detail. Kodak's consistent advancements in film chemistry ensured that the photos taken with the Kodak III would stand the test of time, maintaining their vibrancy and clarity.

Another hallmark of the Kodak III was its durable construction. Built to withstand the rigors of everyday use, the camera was encased in high-quality materials that provided protection against environmental factors. This robustness made it a favorite among photographers who required a reliable tool that could endure various shooting conditions.

Moreover, the Kodak III features various shutter speeds, allowing photographers to experiment with different exposure settings. This flexibility encouraged creativity, enabling users to adapt to varying lighting situations and photograph dynamic scenes, including fast-moving subjects.

In summary, the Kodak III is a classic camera that combines ease of use, high-quality image production, and durability. Its design and technology reflect a commitment to making photography accessible while ensuring that users could achieve excellent results. As a significant player in the evolution of cameras, the Kodak III supports a rich legacy that continues to inspire photography enthusiasts to this day.
