Keyence - Everything you need in automation
While the name might be new or strange to most end users, it is quite famous in automation industry through reputation and supports provided. Among many suppliers, I favor Keyence even though the price of the products such as sensors is slightly higher than most of the rest.

There are a few reasons why I favor keyence compare with others:

Direct Approach
Keyence sales engineer are technically well trained and able to provide quality automation solution most of the time. Through this service, customers get the highest advantage due to faster feedback and time saving. As an engineer, you definitely have a bigger job scope than just buying and replacing sensors. As time is really an important factor in production, you can't waste too much time waiting for reply and sourcing for the right parts. This is the time when you will find Keyence most useful. The Keyence sales engineer will normally feedback to your question as soon as possible and most of the time within a day. If there is any technical issue regarding the parts you purchase, you can call up nearest keyence branch and deal directly with the sales engineer and expect a speedy reply. Whereas, if you were to purchase from a trading house, you will find difficulties when urgent technical support is required. Most of the time, traders do not have the expertise to resolve your problem as what they do is just selling. That will actually increase the down time of your machines which cost a lot more than the amount you tried to save.

Trial Unit
Other than providin faster feedback through direct sales, keyence also offer trial unit to their customer. This actually show their confidence in the products they offer. If you think that you have no confident with the products proposed to you, you can always request for a free trial unit. During this trial period you can actually install the trial unit to your machine and monitor the progress. If the results is satisfying, perhaps you should consider purchasing it. Otherwise, you can just return it and Keyence does not charge you any additional fees for that. Apart from that, keyence has the most friendly and humble sales person in the industry. Many suppliers actually require customer to purchase in bulk in order to gain product support. In Keyence, even it is just a single unit, they will still provide excellent service to their customers. Good job Keyence!

Faster Delivery Service
Apart from all the excellent services provided, Keyence make it even better when they actually provide you a very fast delivery service. The products are shipped from Japan warehouse to worldwide. Even though the products come from Japan, most of the local branch actually keep stocks of most commoon products. Hence, the 1 day delivery service is always possible if the stocks are available.

Product Demo
The last but not least, the things that i like most about keyence is, they do products demo on most of the products the sales engineers proposed. They actually walk the talk. Most of the time they show some impressive demo and you can see that keyence really trained their sales engineer so well. Other than discipline, the sales engineer are trained to be creative as well. You will really see interesting demonstration of the products with Keyence sales engineers. That will actually help to generate ideas on improvement projects.

Now don't you think Keyence is going to be useful supplier?
