Encoders - DPL12SH2424A25K1 Application Field and Working Principle

Encoders are typically used to provide feedback on the position of actuators or to determine the speed of mechanical systems. There are three main types of encoders available, Absolute, Incremental and Rotary Encoders. The DPL12SH2424A25K1 is a robust, heavy-duty incremental encoder, designed for use in harsh industrial environments.

The DPL12SH2424A25K1 features a stainless steel housing, which forms an IP67 rated unit, making it suitable for use in almost any challenging environment. It has a 12mm diameter (6mm pitch) keyed shaft, supplied with a 90° metal key and a 24mm square flange. The DPL12SH2424A25K1 is designed to provide a high resolution output signal, with a 2.4mm mechanical resolution and a 24 pulse electrical output.

Application Areas

The DPL12SH2424A25K1 is primarily used in industrial automation, process control and manufacturing applications, for applications such as speed and position feedback control. It can be used to provide feedback on the position of actuators or to determine the speed of mechanical systems. It is ideal for use in motorized applications, such as mowers, conveyers, pumps, linear actuators and robotic systems.

Working Principle

The working principle of the incremental encoder is relatively simple. The main component of the encoder is a code disk, which is usually made of plastic or glass. The code disk has a series of concentric tracks on its surface, each track consisting of a set of transparent and opaque segments. When the code disk is rotated, it moves past a light source and a light detector, which are positioned at adjacent points and connected to an electrical circuit.

As the code disk rotates, each transparent and opaque segment of the code disk\'s tracks pass by the light source and the light detector. This causes the circuit to generate electrical pulses, which represent the position of the code wheel relative to a reference point. A counter can then be used to measure the relative position of the wheel by counting the number of electrical pulses generated. This is then transferred to an output stream, which can be used to determine the speed, direction and position of the system.

The DPL12SH2424A25K1 is an excellent choice for applications where space is limited, due to its small form factor. It is also highly reliable, with its robust stainless steel housing, and is capable of providing accurate, high resolution feedback signals in even the harshest of industrial environments.
