Product Description:

Built by under the patent name EA170-31100 Snaplock Limit Switch delivers robust consistent performance in precision-demanding industrial applications. Within the Snaplock Limit Switches product series this model offers two normally open and two normally closed Form Z contacts to accommodate different control and safety system requirements. This secure operating device protects machines and systems that require the precise limit detection to both control movement and protect equipment from damage. A die-cast zinc/aluminum housing of the EA170-31100 provides outstanding resistance to corrosion.

The durable housing construction provides the reliable performance of the switch in demanding environments which makes it perfect for applications in manufacturing and automation industries and machinery use. The built-in design of the switch improves longevity because it resists degradation when used over long periods under harsh operating conditions. The device functions effectively across temperatures between 0°C to 90°C which guarantees steady operation at both hot and cold temperature points. The device shows the versatility by working well in many industrial applications which need stable operational performance.

The device operates with continuous currents extending to 20 Amps at 120 VAC which enables it to handle the heavy electrical loads efficiently. These enclosures from the EA170-31100 operate under NEMA 1, 4, and 13 specifications to defend against dust, moisture and environmental hazards. This switch meets the stringent nuclear standards of IEEE which proves its suitability for critical applications. The industrial environment benefits from the EA170-31100 Snaplock Limit Switch because it unites the reliability with durability and flexibility when used in demanding conditions. This device maintains its reliability as a trusted solution because its corrosion-resistant housing supports high current ratings under wide temperature ranges.
