SEACON offers a variety of switches. This Modular Proximity Switch utilizes many of our proven proximity switches and integrates them with a SEACON Micro WET-CON, underwater plugable connector.

Installation has never been easier. Once the switch is mounted the cable can easily be added. Because a wet plugable connector is used, this can be done in any conditions, even submerged.

As a result of this modular design, switches become interchangeable. Simply replace the cable and the switch can be used eleswhere. This is particularly useful when taking spares to sea.

Key Features

  • Hermetically sealed
  • No O-rings or gaskets
  • Single Pole Double Throw
  • Reinforced Neoprene Mold
  • Integrated Underwater Plugable connector incorporating MC-BH-3M

AU-VM Series, AU-VME Series, BU-VM Series.

Standard Proximity - The switch can be normally open or closed. When a magnet is presented the switch will either open or close the circuit.

Sinking Hall Effect - The sensor is normally closed. When a magnet is present the sensor opens at a very high rate of speed.

Sinking/Sourcing Hall Effect - The switch is normally open and will gradually close as the magnet is brought closer to the switch. This is ideal for lining up two objects.

Latching Hall Effect - The circuit is closed when a South magnet is present and opens when a North magnet is presented.

Principle Of Operation

A Modular Proximity Switch uses magnets, either in attraction or repulsion, to open or close an electrical circuit.
Except for hall effect, all switches are single pole double throw.
