2Wire NPN PNP Magnetic Proximity Switch — suitable for pneumatic cylinders (models CMSG, DMSE, DMSH, CMSJ; single-piece DMSJ Electronic 2wire) Key benefits Reliable, non-contact position sensing: magnetic proximity detection eliminates mechanical wear points for longer service life and consistent performance. Simple integration: 2-wire electronic design with options for NPN or PNP outputs fits typical industrial control inputs and wiring practices. Compact, single-piece package: DMSJ singlepiece construction reduces installation complexity and saves space on pneumatic cylinders. Clear status feedback: provides reliable on/off detection of piston position for machine safety, sequencing, and process control. Low maintenance and high availability: sealed sensing avoids contact contamination and reduces downtime. What it does Detects magnetic targets on pneumatic cylinder pistons using magnetic proximity technology. Outputs a clean switching signal (NPN or PNP) to indicate piston presence or travel limits. Available in models CMSG, DMSE, DMSH, CMSJ and specifically as the DMSJ Electronic 2wire single-piece sensor for direct mounting. Compatibility and form factor Designed for use with pneumatic cylinders and similar linear actuators. Single-piece DMSJ variant mounts directly to the cylinder profile for straightforward installation. 2-wire electrical connection minimizes wiring complexity; available in NPN or PNP output configurations to match your control system. Performance and reliability Magnetic sensing provides repeatable, contactless detection for consistent cycle counts and position monitoring. Sealed electronic housing reduces exposure to dust and typical industrial contaminants. Intended for continuous industrial use where accurate end-of-stroke or intermediate position sensing is required. Typical applications Cylinder end-of-stroke detection for automated assembly lines to confirm piston position before downstream operations. Safety and interlock monitoring to prevent tooling collisions by confirming cylinder retraction or extension. Cycle counting and preventive maintenance tracking by feeding reliable position signals into PLCs or machine controllers. Installation and use notes Select the appropriate model (CMSG, DMSE, DMSH, CMSJ) and output type (NPN or PNP) to match your cylinder and control wiring. DMSJ Electronic 2wire single-piece units mount directly on compatible cylinder profiles; verify mounting dimensions with your cylinder manufacturer. Use the sensor’s switching output to interface with PLC inputs, relays, or other control devices for status monitoring and control logic. Models and naming Product family includes CMSG, DMSE, DMSH, CMSJ. This listing refers specifically to the DMSJ Electronic 2wire single-piece magnetic proximity switch with NPN/PNP wiring options. Reliable, compact magnetic proximity sensing for pneumatic cylinders — accurate position feedback with minimal installation and maintenance.
