Magnetic proximity sensor from C&K for harsh and dirt-prone applications

C&K has announced expansion of its magnetic proximity sensors offerings. The new MPSR Series feature ruggedized aluminum housing and a stainless steel cable making it suitable for use as sensors in dirty environments. With the ability to operate upto 4 million actuations, it can withstand dirt, dust, oil, grease, water, and other potential contaminants that would degrade performance of other sensor assemblies.

By having Form C switching where two outputs can be toggled to offer additional feedback capabilities, the MPSR Series is suggested for automotive, factory automation, industrial, IoT, security, and other applications.

These switches use hermetically sealed contacts to insulate electrical switch contacts from the outside environment, eliminating the risk of sparks.

"Magnetic proximity sensors offer non-contact object detection beyond the normal limits of products such as inductive sensors. They offer long sensing ranges within a small package size, and they can be positioned in different locations through the use of a wiring harness," ?said Tanios BouRamia, Global Product Manager at C&K. "Featuring a durable aluminum housing with maximum protection from the elements, the rugged MPSR Series magnetic proximity sensor enables remote monitoring in most any environmental conditions."

The normally open contacts on the MPSR Series sensor are open when the accompanying magnet is removed from proximity to the sensor, and they are held closed when the magnet is within actuation range. Conversely, the normally closed contacts are closed when the magnet is removed from proximity to the sensor, while they are open when the magnet is within actuation range. The 30V 3W rating means that the sensor can be used for either signal level or load switching as required by the application.

The operating temperature range is -40 F to 176 F (-40 C to 80 C), permitting operation in harsh thermal environments. The sensor is UL61058 approved.
