EA800 Neutral Position

Heavy Duty Limit Switches
Built for precise industrial control

The EA800 series delivers rugged snap-lock switching for harsh environments, offering neutral position and maintained position cam options with bronze or aluminum enclosures and a wide range of certification-ready features.

Product Overview

High-performance limit switch technology, engineered for reliable industrial use.

Designed to withstand hazardous locations and heavy duty applications, the EA800 series uses cam-type SNAP-LOCK® technology for dependable contact action, flexible lever motion, and compact installation.

Standard EA800 switches are supplied with the combination B1/B2 cam, supporting CW and CCW action with both single action and double action modes.

The neutral position cam is ideal for applications that require the lever and cam to return to a defined resting state after operation. Maintained position cams are available for stable contact hold in one or both directions.

How to Order

Simple EA800 ordering structure for reliable switch selection.

Use the EA800 order code to select enclosure material and operation mode. The product variation code defines the contact arrangement for 1NO/1NC, 2NO/2NC, or 3NO/3NC.

Operation Code

0 = CW only or CW & CCW, 1 = CCW only, 1 = CW and CCW (depending on assembly).

Enclosure Code

4 = Bronze, 5 = Aluminum.

Contact Type

1 = 1NO/1NC, 2 = 2NO/2NC, 3 = 3NO/3NC.

For Maintained and Neutral Position EA800 Series, consult factory.
