EPC's Absolute Encoders Now Offer Improved Electronics
Absolute encoders provide a unique code for each increment of shaft rotation, meaning that an absolute encoder indicates both that the shaft position has changed, and the absolute position of the shaft. EPC offers both single-turn and multi-turn absolute encoders, on both shaft and blind hollow bore, with a variety of housing sizes, shaft diameters, signal types, and resolution. Communication protocols include SSI, CANOpen, and EtherCAT.

00:00:00 [Music] rotary encoders are often used to provide feedback for speed and direction of a rotary shaft however in many motion control applications it's necessary to also know exact shaft position at a given point in time in such instances an absolute encoder is a preferred solution an absolute encoder can provide a unique position value within a 360-degree shaft
00:00:33 rotation as well as indicate how many revolutions have been completed this capability eliminates the need for rehoming or running a calibrating procedure upon powerup absolute encoders are ideal for safe operation of systems that always need exact location information to prevent damage to equipment or bodily injury this is especially true in the event of a loss
00:00:59 of power scenario M EPC absolute encoder has the capability of maintaining position value without being powered so if there is rotation during the power loss this movement is tracked single turn absolute encoders are ideal for applications for short positional movements within the single turn of a shaft drum or rotary stage consider a
00:01:22 satellite dish rotating to an exact angle to pick up and track a signal from orbit or perhaps an automated guided vehicle that is steering itself around a corner or making a turn multi turn absolute encoders are suitable for long distance runs or more complex functions for example a multi turn encoder will provide the exact location of a stage driven by a lead screw where the screw
00:01:48 rotates hundreds of times to drive the stage to a position another instance would be a linear multifunction processing machine where a unique action such as filling sealing or labeling occurs at specific locations as a product travels on a conveyor belt as more equipment and industries rely on real-time data absolute encoders are an excellent motion feedback solution there
00:02:14 is no longer a need to use additional devices and time to calculate positional data absolute encoders offer real-time information and many have the capability to connect to an Ethernet network EPC offers both single turn and multi turn encoders in several mechanical configurations and with several communication protocols encoder package sizes range from 36 millimeter to 58
00:02:39 millimeter to two and a half inches with blind hollow boar or shafted options presently EPC serial protocols include SSI and can open as well as network capability via EtherCAT DBC absolute encoders also feature high multi-turn resolution up to 43 bits and magnetic turns counting with no gears or batteries contact encode a products company today regarding your absolute
