Micro Electric Limit Switch

Micro Electric Limit Switch

This product is the E50SA switch body, a core component of the Eaton E50 series of modular, plug-in limit switches. Designed for heavy-duty industrial applications like those found on concrete mixer trucks, it provides reliable position sensing for components such as chutes and hoppers. Its robust, die-cast zinc construction and high NEMA/IP ratings ensure protection against physical abuse, moisture, and chemical contaminants common in harsh environments. This modular body allows for easy replacement and inventory management, as it can be combined with various actuator heads and wiring receptacles to suit specific application needs.

Key Features

• Modular, plug-in design for application flexibility and simplified maintenance.
• Heavy-duty die-cast zinc enclosure for durability in harsh industrial environments.
• SPDT/1NO-1NC contact configuration.
• High environmental protection ratings including NEMA 1, 3, 3S, 4, 4X, 6, 6P, 13 and IP67.
• Wide operating temperature range of -40°F to 250°F (-40°C to 121°C).
• Standard Viton gaskets and seals for chemical resistance.
