Choose underwater proximity switches, mechanical limits or linear position sensing. Compare mounting, materials and cable options for your application.
Choose the job first. Then compare the mounting, connection and material options within that range.
Match the body, thread and cable exit to your drawing. A different thread or larger housing does not, by itself, mean better sensing performance.
Choose the Nano, Micro, Circular or cable-connected arrangement around the required mating interface, pin assignment and cable route. Connector names alone do not establish compatibility.
Specify the body and connector materials separately, together with the water conditions, pressure, temperature and electrical load. Confirm the final assembly against its agreed specification.
700 bar external pressure · 12 mm nominal mounting diameter · Wet-mateable Nano connector
Explore the Nano M12 ↗700 bar external-pressure capability in an ultra-compact M12 switch with an integrated Nano subsea connector. For deep-water position feedback where mounting space and connector clearance matter.
Nano, Micro and Circular are wet-mateable connector families. Choose Micro Straight or Micro Right Angle (90°) to suit the cable route. M12, M18 and UNF describe the switch mounting thread.

Specify depth with the complete assembly. The Nano M12 SS configuration is rated to 700 bar (approximately 7,000 m seawater). Other combinations need their own agreed pressure/depth rating, including the connector and cable termination.

Explore this option ↗Underwater proximity switches and submersible position sensors are selected around the mechanism they monitor. Use this brief to connect the product choice to your actual installation.
Start with a subsea configuration whose sensing method and connection suit the mechanism. The Nano M12 uses an MT-01 magnetic target; a mechanical limit switch is physically actuated. Compare the published operating limits and select the switch, mating connector and cable for the complete installation.
Review the sensor body, connector shell, mounting hardware and target carrier together. For the Nano M12, the Rev 01 specification lists a 316L stainless-steel body and titanium connector. Include water conditions, temperature, external pressure and service access in the selection.
Continuous submersion is more specific than splash protection. State pressure, immersion duration, water chemistry and temperature, then define actuation force, travel and reset for a mechanical switch. Match the complete cable and connector assembly to that duty.
The terms can overlap in application searches, but they do not specify the same operating mechanism. A proximity switch detects a target without physical contact; a mechanical limit switch requires actuation. Choose by target, travel and switching duty before comparing mounting and connections.
A discrete proximity switch indicates a defined position rather than a continuous stroke value. Where the control system needs proportional position feedback, review the linear transmitter, required stroke, output and installation arrangement.
An ingress designation alone does not define your complete operating duty. Agree the immersion conditions, pressure, temperature, materials, cable interface and acceptance requirements for the assembled product.
Submit the switch function, mounting envelope, electrical requirements and cable route together. DepthLink can review the sensor, subsea connector, cable and termination as a complete configured solution.
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.
