PRODUCT OVERVIEW
The Encoder-Flex 1024 is a rotary shaft encoder designed to detect shaft speed, shaft
position, gate position, and shaft direction. This solid-state encoder features
electronics that are potted and totally sealed in a stainless steel body and are
completely mechanically isolated from the rotating shaft. Because the shaft does not
enter the sensor body, there are no entry points for moisture and dust ingress.
The Encoder-Flex 1024 comes standard with Modbus RTU communications and can
be programmed from 1 to 1024 targets per revolution with free PC software. This
software also provides a dashboard of the sensor position and calibrated parameters.
The running mode and calibration can be configured using the free software or
included calibration magnet.
The Encoder-Flex 1024 is powered via a 12-24 VDC supply and provides the following
outputs:
•Quadrature Pulse (Speed/Relative Rotation)
•4-20mA or 0-20mA (Speed/Absolute Position/Multi-Turn Absolute Position)
•RS485 Modbus (All Properties)
The quadrature pulse output is a normally dual-channel signal that can be used with
a PNP or NPN input device. See “PNP Pulse Output Wiring Example” for a sample
PNP wiring diagram using just the A channel.
