Product Description:
Danaher's Snaplock Limit Switches series model EA170-41302 meets all industrial and nuclear environment demands through its rock-solid, robust design.
This switch supports double-pole double-throw operations with NEMA Form Z contacts, which provides complete flexibility for different environmental applications. This product uses Rocker Type SNAP-LOCK technology, which reacts fast and reliably because of its quick make and quick break feature. The EA170-41302 nuclear-grade switch meets all IEEE requirements from 344-1975, 323-1974, and 382-1972, making it perfect for safety-critical settings. The housing model consists of zinc die-cast material with stainless steel pieces on top and bottom to stand up well against tough environmental elements. The switch contacts receive gold plating to lower electrical resistance and deliver dependability through countless operations. This switch handles NEMA 1-4-13 ratings, which means it will keep out dust particles and protect against water and oil effectively for demanding environments. The device runs between 0degrees C and 90degrees C of normal temperature while being able to endure short periods of up to 175degrees C hot temperatures. Adjustability on the device comes through its lever capability that rotates 7degrees30' at intervals from 0 to 173degrees to match different operational setups.
It offers plenty of wiring room to handle nine conductors without problems. It offers default travel configurations and lets users select shorter travel modes to customize its functioning. When set to standard travel, the motor requires 23 inch-lbf of torque to actuate, while short travel boosts that resistance up to 32 inch-lbf. The EA170-302 weighs 3.5 pounds, and the EA170-402 weighs 4.5 pounds, which shows it is strong enough for industrial use while keeping the weight reasonable. Users can match various industry needs through multiple shafts and mounting choices that include standard, wide, and long designs, plus front/reverse positioning and direction/travel settings selection.
