GMA-MT Series Modbus-TCP Interface Ethernet Multi-Turn Absolute Encoder

short description:

GMA-MT Serie encoder is an Modbus-TCP interface cooper-gear-type multi-turn absolute encoder with housing Dia.:58mm; Solid Shaft Dia.:10mm, Resolution:Max.29bits; MODBUS TCP/IP is a variant of the MODBUS family of simple, vendor-neutral communication protocols intended for supervision and control of automation equipment. Specifically, it covers the use of MODBUS messaging in an ‘Intranet’ or ‘Internet’ environment using the TCP/IP protocols. The most common use of the protocols at this time are for Ethernet attachment of PLC’s, I/O modules, and ‘gateways’ to other simple field buses or I/O networks.

Housing Dia.:58mm

Hollow/Solid Shaft Dia.:10mm

Resolution:Max.16bits, Single turn max.16bits, Total Max.29bits

Supply Voltage:5v,8-29v

Interface:Modbus-TCP

6. Ordering & Selection Instructions

Step	Description
1	If you have used encoders from other brands, please provide the original brand/model information. Our engineer will advise you on an equivalent replacement with high cost performance.
2	For a new application, first select the encoder type: 1) Incremental Encoder; 2) Absolute Encoder; 3) Draw Wire Sensors; 4) Manual Pulse Generator.
3	Choose the output format (NPN/PNP/LINE DRIVER/PUSH PULL for incremental encoders) or interfaces (Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, Modbus TCP).
4	Select the resolution: Up to 50,000 ppr for Gertech incremental encoders; up to 29 bits for Gertech absolute encoders.
5	Choose the housing diameter and shaft diameter based on your installation requirements.

8. FAQ Overview

No.	Question	Summary of the Answer
1	How to choose the right encoder?	First, determine the type (incremental or absolute), then consult with the sales/service department.
2	What specifications are required before ordering?	Clearly specify encoder type (solid or hollow shaft), housing diameter, shaft diameter, phases & resolution, output mode (NPN/PNP/voltage/push-pull/line driver), and supply voltage.
3	How to select the proper encoder by yourself?	Review the detailed specification description, check the installation dimensions, and contact the supplier for more details.
4	What is the minimum order quantity?	The MOQ is 20 pieces; ordering fewer pieces may result in higher freight costs.
