Confirm final materials and interfaces for your selected configuration.
A compact magnetic proximity switch for discrete position feedback on submerged equipment. The M12 × 1.0 threaded 316L stainless-steel body has an integral titanium Nano six-pin male subsea connector. Volt-free SPDT contacts change state when the optional MT-01 target magnet approaches within the specified 12 mm sensing range. Supplied as a switch; order the target and mating cable separately.
Choose the Nano M12 for a compact magnet-operated sensing point. Mount the switch on the fixed structure and the MT-01 target on the moving part. It reports a defined position through changeover contacts.
Switch supplied separately from the optional MT-01 magnet and mating cable.

The M12 mounting thread describes the switch body, not the space needed for the complete connected assembly. Use the dimensional drawing to plan the sensing point, then allow for the mating connector and cable route.
Check the threaded mounting length, locknut access and clearance behind the Nano connector. Include the mating plug, cable bend and room to connect or disconnect the assembly. A short sensor body alone does not establish the installed envelope.
Specify the target magnet and approach direction with the operating gap. Check the closest and furthest target positions, mounting tolerances and nearby ferrous parts. Verify the switching and release points on the mechanism before setting the final stops.
Give the maximum working depth, pressure, water temperature and immersion duration. Check the selected switch reference, mating cable and termination against that duty. Wet-mate capability describes the interface; use its supplied mating procedure and operating limits.

Discuss this Nano installation ↗The Nano M12 Rev 01 datasheet specifies continuous submersion, 700 bar external pressure and an approximate 7,000 m seawater depth rating. The Nano connector is wet-mateable. Select the mating cable and termination for the same installation and follow the supplied connector mating procedure.
The switch body is 316L stainless steel and the connector body is titanium. Include the mounting material, water conditions and cable route in your enquiry. Check the target carrier, fasteners and mating connection as part of the wetted assembly.
The Nano M12 requires a magnetic target. The specified sensing range is 12 mm with the optional MT-01 magnet. A plain metal insert is not an equivalent target. Allow for alignment and movement tolerances through the full mechanism travel.
| Item | Reference | Supply |
|---|---|---|
| Nano M12 switch | DL-PS-B33-1A-NAN6-SS | Switch only |
| Magnetic target | MT-01 | Optional; order separately |
| Mating cable | Specify Nano mating half and pin assignment | Length and termination to suit the installation |
Flush mounting is possible; ferrous-steel supports are not recommended for this magnetic arrangement. Include the mounting material and drawing with your enquiry.
Selecting a subsea proximity switch or submersible position sensor starts with the duty: valve position, actuator travel, gate position or tool engagement. Review the sensing target, mounting, switching load and operating conditions alongside the cable assembly.
