CEI managing director Ray Berst shares his anecdotes and the trials and tribulations of developing camera cases for the machine vision industry.
Components Express, Inc. (CEI) is in its 27th year of trading. The company had attained a position as the largest manufacturer of Machine Vision Cables in the industry. In 2008 amidst the World financial collapse, CEI in a concerted effort to improve its business made a bold move. CEI decided that it would strive be the best in the world at producing machine vision cabling, but that was over 10 years ago. It was time for another great product.
We decided that we either had to make cabling for markets other than machine vision, or expand our offering by developing a brand new product line for the vision industry. CEI would have to assess both its manufacturing capabilities, and technical abilities. CEI had a small machine shop for making its tools and modifying molding tools. The shop had become a playground for engineering and upper management (all gear heads at heart). This combined with what management believed was a lack luster product offering for industrial camera enclosures “Cases” led to the development of CEI first camera case.
The design input for the first unit was limited. It was:
- IP67 / IP69
- Versatile mounting
- NO CORD GRIP
Why no cord grips?
To put it plainly, cord grips suck…
We are a cable manufacturer and I cringe every time I found out one of my customers put a “cord grip” on one of my cables.
Cord grips do exactly what they say. They “Grip” a cable, very tightly. This is very bad for twisted, pairs, or any sort of high speed data cabling. I could go on for hours here talking about reflection, signal degradation or outright cable breakage.
Just like installing a skylight in your new house. It looks cool, but eventually, it’s going to leak and cause the need for a major repair or in our industry, the camera will be destroyed. Try getting that camera replaced after you drown it.
It’s a pain in the butt to install!
The customer has to ideally mill, or realistically drill the cord grip and install the grip on the cable, then they can pray that it doesn’t leak. Also, its time consuming for the customer to replace the failed cable when it finally succumbs to the forces of the cord grip.
