Nano Subsea Proximity Switch - M12 Thread - Titanium Connector

M12 subsea proximity switch with a stainless-steel body and titanium Nano connector. Specify the mounting, sensing target and cable assembly for your underwater position-monitoring application.

DEPTH RATING7,000 mApproximate seawater depth · 700 bar external pressure

Small footprint. Subsea position feedback.

Our ultra-compact switch platform combines an M12 mounting thread with an integrated Nano subsea connector. Choose it when mounting space and connector clearance are limited. Micro and Nano refer to connector families, independently of the mounting thread.

OPERATING PRINCIPLE · Nano Subsea Proximity Switch - M12 Thread - Titanium Connector

How this switch detects position without contact

  1. Mount at the sensing point

    Fix the switch beside the mechanism and mount the specified target on the moving part. The target passes the sensing face at the position you need to detect.

  2. Target enters the sensing range

    The suitable target changes the configured contact state without physically pressing the switch. Confirm the target type, sensing gap and alignment against the exact product drawing.

  3. Connect the position signal

    Route the signal through this product’s specified cable and connector arrangement to the control input. Review the contact function, electrical load and pin allocation together.

  4. Check travel and repeatability

    Verify indication and reset throughout the installation tolerances. A proximity switch indicates a defined position; it does not measure the entire cylinder stroke.

For this product: Use the approved configuration for Nano Subsea Proximity Switch - M12 Thread - Titanium Connector. Confirm mounting thread, target, sensing gap, body and connector materials, cable route and operating conditions.

INSTALLATION & SELECTION

Before you fit the switch.

Can this switch operate continuously underwater?

This is a subsea switch configuration. Specify continuous immersion as an operating duty, including external pressure, duration, water temperature and media. The supplied assembly specification defines its limits, including the actuation interface and cable termination.

What should I specify for use in seawater?

Specify the water conditions and the materials of the housing, connector, mounting hardware and target or striker. Material selection is specific to the installation; a corrosion-resistant housing does not establish the suitability of every connected component.

What target does the switch detect?

Select the target and operating gap for this configuration. A proximity switch indicates a defined position; it does not measure the complete travel of an actuator. Use the product drawing to establish the target, approach direction and mounting clearance.

PRODUCT + APPLICATION ENGINEERING

Underwater position feedback, configured for your equipment.

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.
