2 Wire DC

The 2-Wire DC proximity switch you’ve described is a versatile device designed for controlling external loads in series with the switch. Here’s a breakdown of its key features and technical specifications:

Applications:

  • Industrial automation (conveyor systems, machine controls).

  • Process control (liquid level detection, part presence sensing).

  • Harsh environments (due to IP68 rating and brass housing).

Key Features:

  1. 2-Wire DC Operation

    • Unlike NAMUR-type sensors, this switch can handle higher voltages and currents directly.

    • The load is connected in series with the switch, and the supply voltage is shared between the switch (~6V drop) and the load.

  2. High Durability & Protection

    • Housing Material: Chrome-plated brass (corrosion-resistant, rugged).

    • Protection Class: IP68 (dustproof and waterproof, suitable for harsh environments).

    • Short Circuit & Polarity Protection: Built-in safeguards against wiring errors and overloads.

  3. Flexible Mounting Options

    • Supports flush and non-flush mounting depending on application needs.

  4. Status Indication

    • LED indicator for visual feedback on switching status.
