Absolute Encoder Code:
|
|
|
| |
Your choices are...
|
|
|
| |
Gray
|
|
The device uses a unit-distance coder where only one bit changes with the transition from one measuring step to the next.
|
| |
Binary
|
|
The output is represented in a series of ones and zeros.
|
| |
BCD
|
|
Binary Coded Decimal. The output is represented by decimal numbers (integers) where each digit is signified by four bits.
|
| |
Other
|
|
Unlisted, specialized, or proprietary absolute encoder code.

Search Logic:
|
|
All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
|
|
| |
Incremental Encoder Signal:
|
|
|
| |
Your choices are...
|
|
|
| |
Digital: Square Wave
|
|
Digital output signal lines for direct interface with a processor or co-processor (typical for most encoders). Most typical is a square wave or two square waves that can be resolved via quadrature to four counts per line.
|
| |
Analog: Sine / Cosine
|
|
Analog output involves two channels 90° out of phase (quadrature). The sine and cosine signals may be read and combined. The theoretically infinite resolution is limited only by the resolution of external digitizing device.
|
| |
Single Channel
|
|
Unidirectional or "tachometer" encoders. The single channel allows for one count per physical line.
|
| |
Pulse & Direction
|
|
A direction channel may be combined with single channel counting or multiple-channel counting with quadrature.
|
| |
Reference / Index
|
|
Once per revolution "mark" or "home" position.
|
| |
Other
|
|
Unlisted, specialized, or proprietary incremental output.

|
|
| |
Signal Quadrature
|
|
Signal configuration in which two channels are carrying signals 90° out of phase. These signals can be combined to provide four or more encoder "counts" per line or other indicator.
|
| |
Search Logic:
|
|
"Required" and "Must Not Have" criteria limit returned
matches as specified. Products with optional attributes
will be returned for either choice.
|
|
| |
Electrical / Digital Output:
|
|
The type of electrical signal that will be produced.
|
| |
Your choices are...
|
|
|
| |
Analog Current
|
|
The output is an analog current such as a 4-20 mA or 0-20 mA current loop.
|
| |
Analog Voltage
|
|
The output is an analog voltage such as 0-10V or ±5V.
|
| |
Fiber Optic
|
|
Position data transmission using light transmitted through optical fibers.
|
| |
Serial
|
|
The output conforms to a standard serial format such as RS232, RS422, RS485, etc.
|
| |
Parallel
|
|
The output conforms to a standard parallel format such as general-purpose interface bus (GPIB).
|
| |
SSI
|
|
Serial synchronous interface (SSI) is a general standard for absolute encoders. The physical interface consists of two differential connections aside from power and ground. The controller provides a clock input, and the sensor returns a data signal synchronized to the clock.
|
| |
FOUNDATION Fieldbus
|
|
The FOUNDATION fieldbus is a serial, all-digital, two-way communication system that serves as a local area network (LAN) for factory instrumentation and control devices. It uses a line or tree topology and distributed data transfer (DDT). In the hierarchy of digital networks, the FOUNDATION fieldbus is on the lower end.
|
| |
CANbus
|
|
Controller area network bus (CANbus) is a high-speed serial data network designed for harsh electrical environments and real-time control applications. It operates at data rates up to 1 Mbps and provides excellent error detection and confinement capabilities.
|
| |
INTERBUS®
|
|
INTERBUS® is a fieldbus network based on the cyclic, serial transmission of input/output data between a master and slave stations. Common versions include INTERBUS-S®, INTERBUS-R®, and INTERBUS-MUX® (MUX). INTERBUS, INTERBUS-S and INTERBUS-MUX are registered trademarks of Phoenix Contact GmbH & Co.
|
| |
DeviceNet
|
|
DeviceNet uses controller area network (CAN) network protocol to connect industrial devices such as limit switches, photoelectric cells, valve manifolds, motor starters, drives, and operator displays to programmable logic controllers (PLCs) and personal computers (PCs).
|
| |
PROFIBUS®
|
|
The process fieldbus (PROFIBUS®) is a popular, open communication standard used in factory automation, process automation, motion control, and safety applications. PROFIBUS is standardized in IEC 71158 and IEC 61784 and is suitable for both fast, time-critical applications and complex communication tasks. PROFIBUS is a registered trademark of PROFIBUS International.
|
| |
Ethernet
|
|
Ethernet is a local area network (LAN) protocol that uses a bus or star typology and supports data transfer rates of 10 Mbps. The Ethernet specification is the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. To handle simultaneous demands, Ethernet uses carrier sense multiple access / collision detection (CSMA/CD) to monitor network traffic.
|
| |
SERCOS
|
|
Serial real-time communications system (SERCOS) is an open controller to intelligent digital drive interface specification. SERCOS is designed for high-speed serial communication of standardized closed-loop data in real-time over a noise-immune, fiber optic cable.
