OMRON to Release Newest Addition of Communications Type Amplifier Unit to Contact-Type Smart Sensors
- Easily Transmits, at High-speed, High-precision Inspection Data Obtained at Manufacturing Sites -

June 27, 2014

OMRON Corporation (TSE:6645, ADR: OMRNY) will release a Communications Type Amplifier Unit E9NC-TA0 on July 1, which easily transmits data to a programmable logic controller and the like at high speed, as a new addition to E9NC-T series Contact-type Smart Sensors.

The E9NC-T series Contact-type Smart Sensors, released in April 2013, are high-precision contact sensors that consist of Sensor Heads and Amplifier Units, which can be used for a wide variety of applications; for example, shape inspection and verification of tolerance and press in force performed at manufacturing sites.

At manufacturing sites mainly in automotive and electronics industries, utilizing a large amount of data obtained by multiple sensors and improving traceability are required. Under such circumstances, there are compelling needs to obtain digitalized inspection data and offline measurement data and to simplify processing of those data in addition to performing a usual "ON" or "OFF" determination.

In supporting those needs, the E9NC-TA0 makes it possible to obtain measurement data easily at high speed (at 1 ms max.) by connecting it to an OMRON's Sysmac NJ-series Machine Automation Controller, which is a key part of the Sysmac automation platform, via an industrial network protocol EtherCAT.
It can also transmit data directly to a Microsoft SQL Server by using a Sysmac NJ-series Database Connection CPU Unit and provide an environment that allows for analyzing high-precision inspection data collected at a manufacturing site in real time. In addition, use of a sample screen of OMRON NS-series Touch Screen can facilitate systems of setting change, process changeover, and predictive maintenance. Moreover, use of function blocks which are provided for Automation Software Sysmac Studio easily realizes complicated calculations such as measurement of warp, twist, and thickness without programming.

Sysmac automation platform: Complete machine control through one software and one seamless connection with a variety of I/O devices. Machine and motion programming is fully compliant with IEC61131-3, and the dedicated software suite features functions such as programming, motion designing, and network setting allowing easy control of all connected devices and freeing users to engage in further production innovation.

Main Features

  1. The Amplifier Unit connectable to field networks realizes high-precision data transmission.
    High-precision data measured at a resolution of 0.1 micrometer are transmitted as digital data via EtherCAT.

    high-precision data transmission

  2. Function Blocks (FBs) for easy, eight types of calculations
    Just add Sysmac NJ-series FBs to the host controller to easily perform various calculations such as maximum/minimum value, warp, and thickness calculations.

    Function Blocks for eight types of calculations

  3. Multiple Amplifier Units can be connected easily with reduced wiring work.
    You can quickly and easily connect E9NC-TA0 Amplifier Units to an E3NW-ECT Sensor Communications Unit, and you can reduce wiring work in comparison with the traditional analog output sensors.

    Multiple Amplifier Units can be connected
    *The maximum connectable units are 30 when you use the E3NW-ECT and NJ-series devices.
