Siemens Authorized System House
Siemens System House
Multi-brand component supply

Industrial components from Mitsubishi, Allen-Bradley, Omron, Keyence, SICK and Phoenix Contact

K&N Automation is a Siemens Authorized System House in Chennai. Siemens is the range we are authorised for — it is not the only range we supply. When a machine standard, a customer specification or the part already installed calls for another make, we source it, quote it and build it into the panel. Supplied across Tamil Nadu and throughout India.

What the relationship is

Siemens Authorized System House — and a supplier of every other make

Two different things, stated plainly, so nothing is assumed when you compare quotations.

Siemens — a formal authorisation

K&N Automation is a Siemens Authorized System House in Chennai — the appointment buyers also search for as a Siemens channel partner, authorised dealer or approved system integrator. It means current article numbers, factory engineering support, and the SIMATIC, SINAMICS, SITOP, SCALANCE and SIRIUS ranges quoted from the live catalogue. It is the relationship behind the 258 Siemens article numbers published on this site.

Other makes — supplied to specification

For every manufacturer below we are a supplier, not an appointed distributor, and we say so rather than let it be assumed. We source against your bill of material, your machine builder's standard or the nameplate on the part that failed, and quote it alongside the rest of the package — so you place one order instead of five.

Makes we supply

PLCs, drives, servo, HMI, sensors and safety — whatever make the job calls for

The manufacturers we are asked for most often. If yours is not listed, ask anyway — this is what comes up regularly, not a limit on what we can source.

Mitsubishi Electric — PLC, inverter and servo

MELSEC iQ-R, iQ-F and FX programmable controllers, FR-series inverters, MELSERVO servo drives and motors, and GOT operator terminals. Common on imported machinery and on plants standardised around Mitsubishi control.

Allen-Bradley / Rockwell Automation — PLC, VFD and HMI

ControlLogix, CompactLogix and Micro800 controllers, PowerFlex variable frequency drives, Kinetix servo, PanelView operator terminals and Guardmaster safety products. Usually specified by American and European OEMs and by corporate engineering standards.

Omron — controllers, sensors and safety

NX and NJ machine controllers, CP-series compact PLCs, 1S servo systems, photoelectric and proximity sensors, safety relays and light curtains. Strong where the sensing and the control come from one supplier.

Keyence — sensing, measurement and vision

Photoelectric, laser and displacement sensors, measurement systems, vision and code readers. Specified where the measurement has to be repeatable, not merely present or absent.

SICK — safety and industrial sensing

Photoelectric and proximity sensors, safety light curtains, safety laser scanners, encoders and identification products. A common choice for the safety sensing on fenced cells and material handling.

Phoenix Contact — terminals, relays and power

Terminal blocks, interface relays and couplers, power supplies, surge protection, industrial connectors and marking. The components that quietly decide whether a panel is pleasant or painful to maintain in five years.

Brand names and product designations are the trademarks of their respective owners and are used here only to identify equipment we supply. K&N Automation is an authorised Siemens System House; for the other makes listed we act as a supplier.

Why buy it through us

The components are the easy part

One order, one quotation

A mixed panel might need a Siemens controller, a Mitsubishi inverter, SICK safety sensing and Phoenix Contact terminals. Four suppliers means four lead times and nobody responsible when they disagree. We quote it as one package.

Selected by the people who wire it

The same engineers who specify the components build the panel and commission it. A part that looks equivalent on a datasheet and is not gets caught at selection, not on site at two in the morning.

Built in, not just delivered

Components can be supplied loose, or designed into a finished assembly — wired, tested and documented. See control panel manufacturing for what that includes.

Questions we get asked

About supplying other brands

Are you an authorised Mitsubishi, Omron or Allen-Bradley distributor?

No, and we will not imply otherwise. Our formal authorisation is with Siemens, as a Siemens Authorized System House. For Mitsubishi, Allen-Bradley, Omron, Keyence, SICK and Phoenix Contact we act as a supplier: we source the parts, quote them and stand behind the delivery, but we are not an appointed channel for those manufacturers.

Can you build a panel that mixes Siemens with another make?

Yes, and most panels do. A Siemens controller driving Mitsubishi inverters, SICK safety sensing on the guarding and Phoenix Contact terminals throughout is an ordinary combination. What matters is that whoever selects the parts understands how they behave together — which is why the people who specify them here are the people who wire and commission them.

I only have the old part. Can you find the replacement?

Send a photograph of the nameplate. Between the make, the model and what the machine does, an engineer can identify it and offer either the same part or a current equivalent, with the differences spelled out rather than glossed over. Attach it to an enquiry and you will get a considered reply.

Do you supply outside Chennai?

Yes. We supply across Tamil Nadu and throughout India from Chennai, and our engineers have commissioned industrial systems in nineteen countries since 2003.

Send the part number, or a photograph of the one that failed

A bill of material, a machine standard or a picture of the nameplate is enough to start. An engineer reads it and quotes against it — whatever the make.
