Encoders: EM14R1D-M25-L032N Application Field and Working Principle of Encoders

Encoders, used for sensing and measurement applications, come in various forms, from linear to rotary. Among them, radial encoders are a type of rotary encoders and their range of applications is wide and varied. The EM14R1D-M25-L032N is a radial encoder manufactured by Panasonic. This article starts by discussing the application field of the EM14R1D-M25-L032N. This is followed up with an in-depth look at the working principle of radial encoders.

Application Field of the EM14R1D-M25-L032N

The EM14R1D-M25-L032N is a radial encoder with a resolution of 32 CPR (counts per revolution) and a maximum angular rotation of 360°. It is equipped with a hole for mounting and is ideal for applications such as medical imaging, robotics, automation, positioning systems, motors and machine vision systems.

This encoder is perfect for applications requiring high accuracy and precision measurements. Its slim design provides it with a wide range of motion. It also has an excellent response time, making it an incredibly reliable solution. The EM14R1D-M25-L032N is also designed with noise reduction features. This ensures the integrity of the signal during operation.

Working Principle of Radial Encoders

Radial encoders are used to measure the position and velocity of a rotating shaft. This is usually accomplished with the help of two methods, absolute and incremental. Absolute encoders measure the angular position of a shaft relative to a reference position at power up, while incremental encoders measure the distance moved from a reference point when the shaft is rotated; thereby providing position information.

To do this, scaled discs, also known as code disks or scale discs are attached to the shaft that is being measured. These code disks are marked with an alternating pattern of light and dark areas. These patterns are known as marks or encoder tracks and consist of a reference track and a data track. The reference track consists of a pattern of dark, light, and index marks, which are used for reference position and direction recognition. The data track consists of either gray code or binary code representing the angular position of the shaft.

To measure the position or velocity of a shaft, manufactured encoders use sensor heads consisting of photosensors or photodiodes, which provide pulses to the encoder. The pattern of these pulses is then compared against the track pattern of the code disk; thereby providing position and motion information.

The EM14R1D-M25-L032N radial encoder is an exceptionally reliable option for various industrial and process automation applications. Its finely tuned design and slim construction make it a great choice for applications requiring high-resolution and accuracy in angular measurements.
