# What are the interfaces available in BTL?

## Different interfaces of BTL

Micropulse transducers are available with a variety of different interfaces and can thus be  
easily connected to controllers or simple display or processor units.  
Generally differentiates between the analogue and the digital interface.

- Voltage output  
  The output voltage is directly proportional to the position of the position transducer on  
  the measuring section.
- Current output  
  The output current is directly proportional to the position of the position transducer on  
  the measuring section.
- Pulse interface  
  The time between a polling and the response pulse is directly proportional to the position  
  of the position transducer on the measurement path. The transmission of the impulses  
  with RS485 / 422 differential drivers guarantees interference-free transmission up to 500  
  m cable length.
- Synchronous serial interface SSI  
  The position of the position transducer on the measuring path is transmitted serially to  
  the controller in a data word. Micropulse position transducers with SSI interface can be  
  connected directly to controllers or axis control cards with an SSI interface.
- Digital I/O interface  
  The displacement sensors can be directly connected to the controller via digital inputs /  
  outputs and is therefore a cost-effective solution compared to analogue coupling.
- Quadrature interface  
  The encoder with quadrature interface is connected directly to a standard rotary encoder  
  interface (90 ° phase shift, A & B)

  BTL distance sensors are also available with network interfaces.
