While there are hundreds of part numbers in our waterproof limit switch line, there’s only a couple basic ideas you need keep straight to understand how it all works.
For the engineers among you, here’s an equation that might help. (Sealed Pendant Switch) + (Mounting Bracket) = Your Ideal Waterproof Switch! CPI’s Sealed Waterproof Pendant Switch Of course then there are a boatload of electrical, temperature, endurance, and ergonomic options you can specify for your basic pendant switch. Likewise there are numerous stainless steel mounting brackets our switches will fit into including lever mount, roller, pipe mount, simulated lever, and of course hundreds of customizable options etc. Some of our clients don’t even opt for a mounting bracket at all, preferring to hand actuate their switch or simply tie wrap it to their cab roll bar, bicycle handle, fishing rod, or whatever other unique application they have. One other option that isn’t spoken about so often is our waterproof panel mount switch option. In this case we not only provide you a panel mount option for your chosen waterproof pendant switch, we provide you the panel too. Waterproof Panel Mount Switches in ActionEnter Loadmaster of Norway Missouri, manufacturers par excellence of refuse collection vehicles (ie. garbage trucks). Loadmaster recently selected such a configuration for their latest fleet of high compaction rear-loaders as shown below: In this application two custom CPI panel mounts were developed that are easily bolted to either the side of the vehicle. Meant to be operated by men with gloved hands, the switches selected allow operators in the rear to signal the driver in the cab when ready to move, or allow the operators to manually advance the compression throttle as a safety feature prior to moving the vehicle. Selected for this was our K1163-501 and K1164-501 Single and Dual Panels respectively, using variations of our high actuation high force pendant switch. High actuation is better for gloved operation and high actuation force insures that the switches wont easily be activated by accident. Panel Mounted Waterproof Pendant Switches for Your EquipmentIf you have a rough duty piece of equipment begging for a reliable waterproof switch, its highly likely we have an off the shelf product that far exceeds the reliability and capability of what you have now. And we can even stick it in a stainless steel waterproof panel for you. Why not make the switch to CPI today? Original content posted on https://www.cpi-nj.com/blog/panel-mount-pendants-keep-the-neighborhood-clean/ Perhaps one of the most memorable moments of my career at CPI happened over a decade ago, when CPI was first asked to produce a robust hydraulic position sensor for a large well known maker of construction vehicles and equipment. In their larger machines, rod-type sensors were being used in the control system of long stroke hydraulics but their installation was problematic, and they often failed in rough conditions.
After many months of engineering and testing CPI produced the first version of our SL series sensors. Our new sensor was durable, accurate, and used a well accepted linear position measurement principle, the draw wire. In our solution however, the draw wire mechanism was completely re-conceived and re-engineered for harsh duty and improved accuracy. The mechanical rotations of the draw wire were ingeniously coupled to an LVDT transducer system so the whole solution was non-contacting and virtually immune to all the environmental hazards, temperature and EMI your average 15 ton wheel loader runs into. The system was so unique and unlike anything that existed that we were able to receive several patents from it. Proudly we demonstrated our achievement to our client, certain that we were onto something big here. Do you know what they said? (wait for it….) “Not high-tech enough”. Maybe you’ve experienced this: one of those moments when words fail you and you’re quite sure your head will explode shortly. You see, having witnessed the amount of research into material science, alloy’s, precision engineering, and component testing that went into our sensor, all I could think was “well define high-tech!”. And so now a decade later, having seen our unique sensor gain wide acceptance in applications more diverse that we ever imagined (including construction vehicles), I’m calm enough to explain in this upcoming series, just exactly what constitutes “high-tech” in our hardened linear position sensor solution, and more importantly, why it outperforms every other sensor technology in the world for extreme duty, long stroke, or subsea applications.
