Regardless of type, all encoders provide a type of orientation that’s used as a reference point for position control.Īn encoder (for industrial controls) is a special sensor that captures position information and relays that data to other devices. They provide information required for the precise control of a variety of applications, such as positioning a rotary table, pick and place, machine assembly, packaging, robotics and more. For this the low range is defined as the ≤ 0.4 V and the high range as ≥ 2.4 V.Updated June 2016 by Lisa Eitel || by Joe Kimbrell, Product manager, Drives, Motors and Motion, AutomationDirectĮncoders are used to determine the position, velocity and direction of motor shaft speed and other mechanical motion. The TTL output is supplied with either a fixed 5 V voltage or a variable voltage of between 10 and 32 V. In a transistor-transistor logic (TTL), both the logical status and the amplification are done by transistors, hence the name.
“Low” is defined as an output of between 0 V and 3 V and “high” as between VCC and VCC - 3.5 V. 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.
The PNP output is an interface based on an output circuit with a PNP transistor. 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. Totem pole output Z48 rotary encoder module external diameter 48mm hole 8mm customizable
