Product Description:

The EA080-22100 from Danaher's Snaplock Limit Switches meets the robust requirements needed in industrial machinery through its product design.

This switch enables fast turning on and off through its 1NO/1NC contacts arranged in a Single Pole Double Throw (SPDT) setup. The product uses Rocker-Type SNAP-LOCK® Technology to produce dependable switch activation that keeps operations safe and efficient. The switch operates precisely because its mechanical movements consist of 10degrees pre-trip, 8degrees differential, 13degrees recommended, and 38degrees total travel at fixed positions. The switch operates within mechanical limits as its torque handling ranges from 14 lb-in in pre-trip to 38 lb-in at total travel. The EA080-22100 operates effectively within a temperature range of -20degrees C to +90degrees C, but users can select it for high-temperature environments up to +150degrees C or low-temperature areas from -40degrees C to +90degrees C. The NEMA 1, 4, and 13 standards enable the unit to withstand water and moisture while protecting against dust and oil intrusion to perform reliably in extreme environmental conditions. The manufacturer selects die-cast zinc because it can resist corrosion more effectively than other materials. The unit supports two types of base installation to fit numerous installation situations. The electrical system covers many voltages and amperages such as 125 VAC at 20A, 125 VDC at 5A, 250 VAC at 15A, and 600 VAC at 5A.

The design ensures enough room to work with size 12 wires plus simple installation of terminal screws for fast maintenance. The switch utilizes Form Z contact connections with marked terminals for easy connection design. The add-on choices include silver contacts that enhance connectivity while defending against wear and special elements, plus lubricants to work well at different temperatures. A special positioning of the shaft can be selected based on the application's unique needs. The switch unit comes with an adjustable 2.3-pound lever that changes settings in steps between 7degrees and 30degrees up to 167degrees total. The switch's internals are made from silver alloy material, which boosts both the electrical conductivity and durability of the component in industrial environments.
