EYE ON NPI – C&K MPSR rugged magnetic proximity sensor #EYEonNPI #digikey @DigiKey @CKswitches @Adafruit
This week’s EYE ON NPI (video) is like a good winter coat – waterproof, super rugged and looks great while doing it. This week we’re back with another C&K Components product: what can we say, they make some great items, and best of all they’re not affected by the silicon shortage, so they’ve got lots of parts in stock!
The MPSR series from C&K are ruggedized magnetic proximity sensors, perfect for automotive sensors and indicators, industrial sensors, anti-tampering and other security and factory automation equipment. The MPSR series sensor and magnet are both sealed in a tough aluminum housing combined with stainless steel wire sleeves. This housing protects the sensors from the harsh environments they are commonly used in, whether oil, water, grease, or volatile chemicals and gases. Manufactured for quick and easy installation, the MPSR series also have a long-life cycle – lasting for more than 4 million actions – and a robust 30 V, 3 W rating.
We’re suckers for beautiful, rugged sensors and enclosures. A lot of times folks use Adafruit parts for prototyping a design and then have to deploy it to The Real World where things get damp, dirty, and dusty. Where dogs or rodents chew on your cables, where coffee is spilled, where folks doing construction go “oops”. Just last weekend, we met someone who does museum exhibit design – which is known amongst engineers as one of the hardest construction challenges because not only does it have to last 10 years, but must do so while getting abused 12 hours a day by absolutely adorable children who are super interested in finding out just how hard they can yank or punch something.
So when we saw this NPI show up on Digi-Key New Products, we decided to highlight it as what we recommend for folks who want to take their designs to the next level. So, yes, please start your design with one of our low cost magnetic reed switch sensors, but when it’s time to do your final install, the C&K MPSR rugged magnetic proximity sensor will survive any kind of environment with IP69 rating (nice). We love the metal coil sleeving and the potted epoxy body. Other than being super swole, it works just like any other magnetic switch, with SPDT contacts so you can use it in NO or NC situations.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
