Neodyn 105P NEMA 1 and 2 Miniature Tamper Proof Pressure Switch

Neodyn 105P NEMA 1 and 2 Miniature Tamper Proof pressure switch is an all-purpose instrument engineered for applications where weight and space are critical constraints. Extremely lightweight and durable, this switch features the efficient Nega-Rate® Belleville disc spring sensing mechanism, ensuring reliable performance in a compact package. Its miniature design significantly improves resistance to vibration and shock, making it an ideal choice for mobile and dynamic industrial systems.

Description

Neodyn 105P NEMA 1 and 2 Miniature Tamper Proof series redefines the capabilities of compact pressure switching. While small in stature, weighing approximately 3 ounces, this switch is built with durable construction to handle rigorous industrial demands. The reduced mass of the unit contributes directly to its operational stability, offering improved resistance to vibration and shock compared to larger, heavier alternatives.

Precision Nega-Rate® Technology

At the heart of the 105P is the patented Nega-Rate® Belleville disc spring sensing mechanism. This technology provides a positive snap-action response, eliminating the set point drift often associated with standard tracing elements. The tamper-proof design ensures that critical pressure limits are maintained without the risk of unauthorized field adjustments, providing a secure “fit and forget” solution for General Purpose (NEMA 1) and Drip-Tight (NEMA 2) environments.
