The NPN Open Collector - The NPN Open Collector(NPN) is an interface based on an output circuit with an NPN transistor.Īn 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. Operating and storage: 35-85%RH(noncondensing)ġ. Most of the encoder series have videos for reference. There are plenty of encoder video if you still have any doubts on encoder, please email us directly or contact online service right now.Īt the same time, you could also visit our YOUTUBY page easily. The more pulse per round, the narrower groovy spacing of grating, ore effect to encoder by vibration, when motor speed is low or even stopped, vibration acting on encoder shaft or encoder shell would cause grating vibration, in this way, encoder might show wrong pulse signal. So we have to pay more attention to encoder working place.
Vibration acting on an encoder always cause wrong pulse easily. Please refer to the table below for a simple example of a push-pull output.Totem pole output Z48 rotary encoder module external diameter 48mm hole 8mm customizable
In the off state it will supply a path to ground and in the on state it will supply Vcc. Please refer to the table below for a simple example of an open collector.Ī push-pull output is a combination of a line driver and an open collector. For proper operation, a sourcing input is required. When in the off state, an open collector will float. In the on state, an open collector will supply a path to ground. Please refer to the table below for a simple example of a line driver.Īn open collector is a sinking output. Because of this, a sinking input is required for proper operation. In the off state, a line driver will float. When in the on state, a line driver will supply Vcc. If you are working with an Industrial I/O Card, check the user manual for the best quadrature encoder type.Ī line driver is a sourcing output. The Push-Pull configuration does not float, it is always supplying Vcc or ground, which is why it will work best with a Multifunction DAQ card. SolutionFor most NI DAQ cards, a Push-Pull quadrature encoder is recommended since Multifunction DAQ card works best when it is constantly driven.
