The bottom plate of the cage is design with limit plate to prevent the camera from slipping out
The cage body is equipped with 1/4 and 3/8 threaded holes, cold shoe mouth, and ARRI gear positioning external interface, which is convenient for external equipment
The cage body is with 1/4 screw to stably protect the camera from slipping out and falling
The cage is designed to avoid the position of the camera button, and doest not obscure the button and battery compartment
With handle: Cold boots and different screw interfaces, can connect with other external devices, with anti slide design. It is convenient and efficient,can use without magic arm.
The rotary encoder can count the number of output pulses during rotation in the forward and reverse directions by rotation. Unlike the potentiometer, the rotation count is unlimited. With the buttons on the rotary encoder, it can be reset to the initial state, that is, counting from 0.
Working principle: The incremental encoder is a rotary sensor that converts the rotational displacement into a series of digital pulse signals. These pulses are used to control angular displacement. The conversion of angular displacement in the Eltra encoder uses the photoelectric scanning principle. The reading system is based on the rotation of the radial index disc (code disc) composed of alternating light-transmitting windows and opaque windows, and is simultaneously illuminated vertically by an infrared light source, and the light projects the image of the code disc onto the surface of the receiver . The receiver is covered with a layer of diffraction grating, which has the same window width as the code wheel. The receiver's job is to feel the changes produced by the rotation of the disc, and then convert the light changes into corresponding electrical changes. Then the low-level signal is raised to a higher level, and a square pulse without any interference is generated, which must be handled by an electronic circuit. The reading system usually uses a differential method, that is, comparing two different signals with the same waveform but a phase difference of 180 in order to improve the quality and stability of the output signal. The reading is formed based on the difference between the two signals, thereby eliminating interference.
