A Hollow Shaft Encoder , also called a Rotary encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital code.

There are two main types: absolute and incremental (relative).

The output of absolute encoders indicates the current position of the shaft, making them angle transducers.

The output of incremental encoders provides information about the motion of the shaft, which is typically further processed elsewhere into information such as speed, distance and position.

Protection grade

IP50 & IP65

Application

Textile industry, motors, packaging machines, industrial lines and even in low temperature industries.

Signal Circuit of encoder

1. The NPN Open Collector -- The NPN Open Collector(NPN) is an interface based on an output circuit with an NPN transistor.

An open collector is the unconnected collector connection of an NPN transistor, whose emitter is connected to earth and whose collector is connected to the output.

2. PNP output

The PNP output is an interface based on an output circuit with a PNP transistor.

3. Push-Pull output(HTL)

High Voltage Transistor Logic functions with a voltage supply in the range 10 and 30 V DC, with 24 V DC being the most usual.

“Low” is defined as an output of between 0 V and 3 V and “high” as between VCC and VCC - 3.5 V.

4. TTL RS-422 output

In a transistor-transistor logic (TTL), both the logical status and the amplification are done by transistors, hence the name.

The TTL output is supplied with either a fixed 5 V voltage or a variable voltage of between 10 and 32 V. For this the low range is defined as the ≤ 0.4 V and the high range as ≥ 2.4 V.
