Photo Chemical Etching for Producing Encoder Disks
Organizations have discovered that investing in a photo chemical etching company that produces encoder disks is an economic and efficient way to make these detailed, vital parts that must be engineered with flawless precision. An encoder disk is a key part of an encoder or sensing device used to enable control systems to identify motion, position, speed, direction, or count when chemical etching is initiated. Encoder disks essentially convert motion into electrical signals. They may be integrated with printed circuit boards, optical components, or magnetic devices; therefore, each disk must be precisely engineered, and the best way to produce encoder disks is achieved with photo chemical etching.
Types of Encoder Disks Produced Using Photo Chemical Etching
Encoder disks come in two primary forms, and photo chemical etching is the best way to produce these heavily detailed parts required for the functionality of sensing devices and encoders. These types of encoder disks are as follows:
Rotary Encoder Disks – Photo chemical etching is used to produce rotary encoder disks. These encoder disks sense the angular position or motion of a shaft or axle. The information is converted to analog or digital signals. Each encoder disk features intricate concentric circles (assigned to specific positions) and opaque and transparent segments. An absolute encoder detects the position of a shaft. An incremental encoder indicates shaft motion, which can provide information on speed, position, or distance. If there is a single miniscule flaw in the production of rotary encoder disks, the part won’t work, and due to the high-quality reputation of photo chemical etching, thi production method is the best option for creating rotary encoder disks.
Optical Encoder Disks – Optical encoder disks are another popular type that require photo chemical etching in their manufacturing to ensure a flawless, economic design. Optical encoder disks work with an electromechanical device that sends an electrical output proportional to the input shaft’s angular position. The encoder disk has a series of opaque and clear segments. The transparent slits enable light from infrared diodes to pass through the disk and reach infrared receivers on the other side, creating an analog signal. This is converted into a digital signal, which is then sent to a processor. Photo chemical etching is used to fortify the flawless functioning of light transference by ensuring the opaque and clear segments are perfectly made, along with the other accoutrements critical to the encoder disk’s functionality.
Why Use Photo Chemical Etching for Encoder Disks?
Photo chemical etching is the best way to produce encoder disks because it meets size proportion requirements, can be used on virtually any level of thin metal thickness, it’s better for the metal being worked, and it ensures there are no fragments that could cause obstruction. Photo chemical etching can be used to produce encoder disks with slots as small as 1.2 times the thickness of the material. Openings can be as small as .006” on a .005” thick material. Etching can also create webs as small as 60% of the material thickness. On a .005” thick encoder disk, the webs can be as small as .004” wide.
At United Western Enterprises our photo chemical etching process adds no extra stress to the metal. It only dissolves excess material, allowing the encoder disks to stay as flat as the material with which we started. Photo chemical etching does not create any burrs on parts, so no obstructions are left behind.
