SSI Output [EA63 AX/DX]
Thanks to the stainless steel enclosure, the encoder is suitable for food and beverage machinery, cranes and winches for ships, offshore applications, washing systems and all those environments where high corrosion resistance is required. EA 63 AX / DX is available with SSI output.
Up to 13 bit
Up tp IP 66 sealing
Parallel, SSI Output [EA58 - 63 - 90 - 115]
ABSOLUTE SINGLETURN PARALLEL ENCODER DESCRIPTION
Resolutions available up to 13 bit and 8192 ppr. Wide application range thanks to several models and different flange types. This series assures high reliability even in the most tough industrial applications. It is available with cable connector output and protection class up to IP 66. Gray and binary code output with several electronics available: NPN, NPN OPEN COLLECTOR, PNP, PNP OPEN COLLECTOR and PUSH PULL.
ABSOLUTE SINGLETURN SSI ENCODER DESCRIPTION
This series is designed to satisfy the new serial transmission philosophy of data output. A 13 bit word data is the standard output for these encoders. Meaningful bits are proportionally to the chosen encoder resolution. This type of transmission reduces wiring issues in order to maintain outstanding device performances. Only a four wire connection is needed: a pair for the position code and the other one for the clock signal. Both signals are transmitted by differential logic. In order to satisfy all dimensional requirements, a wide and complete range of mechanical combinations are available.
PROFIBUS output [EA58 - 63 - 90 - 115]
The Eltra singleturn Profibus encoder series (Identification Number 0x0599) is complying to the Profibus DP standard as described on the European Standard EN 50170 Volume 2. Particularly, Eltra Profibus encoders are according to “PROFIBUS-Profile for Encoders, Order No. 3.062". The Profibus DP interface maintains the same maximum resolution and characteristics (8192 ppr) of the stand-alone version and adds the plus of the Profibus DP network.
Tool change applications [EA 40 T]
? 40 T absolute encoder is specifically designed to be directly mounted on machine tools and it is suitable for being mounted on turrets for tool change (8 or 12 positions). The timing between encoder and turret can be overwiewed by a led mounted on the enclosure. According to that it is possible to visualise the position of the first tool making easier and quicker the mounting for the operator. Main characteristics:
Easy mechanical mounting
Several output types available
8 and 12 position turn configuration
IP 66 sealing
Explosionproof [EAX 80 A/D]
PROFIBUS output [EA63 AX/DX]
Thanks to the stainless steel enclosure, the encoder is suitable for food and beverage machinery, cranes and winches for ships, offshore applications, washing systems and all those environments where high corrosion resistance is required.
Up to 13 bit
Up tp IP 66 sealing
? 120 mm [EA120 P]
The EA 120 is an absolute encoder with through hollow shaft suitable for textile machine, elevator motors and generally all the applications where big diameter shaft is required. EA 120 P is available with SSI output.
Up to 13 bit
Through hollow shaft from 30 to 50.8 (2") mm
Parallel, SSI Output [EAM 58 - 63 - 90 - 115]
ABSOLUTE MULTITURN PARALLEL ENCODER DESCRIPTION
This series is designed for application where a very high precision is required, even also on extended linear distances. Resolutions up to 13 bits on the single turn (8192 ppr) and 14 bits as number of revolutions (16384 revolutions) are available. Sturdy mechanic parts and several flanges make this series suitable in such a wide range of applications assuring high performances even in the most tough industrial applications. This series is available with cable or connector output both with Gray or binary code. The PUSH PULL electronic is suitable for all industrial application fields.
ABSOLUTE SINGLETURN SSI ENCODER DESCRIPTION
The absolute multiturn encoder series with SSI output provides data with the same format as previously described for singleturn encoders. Considering the high data volume in multiturn encoders, the serial data transfer is an efficient solution in order to curb the number of wires and the SSI standard is a valuable one. The output data is a 25 bit word and useful bits are proportional to the resolution chosen for the encoder. This transmission standard efficiently reduces wiring issues maintaining the highest level of performances. Similary to singleturn encoders, number of wires for the transmission is 4 (2 for the data and 2 for the clock signal -both are transmitted in differential logic). A wide range of mechanical parts and flanges designed to satisfy different requirements is available.
PROFIBUS output [EAM 58 - 63 - 90 - 115]
The Eltra multiturn Profibus encoder series (Identification Number 0x0599) is complying to the Profibus DP standard as described on the European Standard EN 50170 Volume 2.
