Description

Neodyn 115PP NEMA 4 and 13 Pressure Switch is the ideal choice for engineers seeking a tamper-proof solution for pressure monitoring. Unlike adjustable switches that can be inadvertently modified, this unit features built-to-order set points, making it a true “set and forget” application device. This design significantly reduces maintenance requirements and enhances safety by preventing unauthorized changes to system parameters.

Advanced Nega-Rate® Technology

Reliability is ensured through the use of the Nega-Rate® Belleville disc spring system. This mechanism separates the electrical element from the pressure sensing element, providing a snap-action response that is highly resistant to vibration and shock. This ensures that the switch actuates precisely when required, even in dynamic industrial conditions.

Durable NEMA 4 and 13 Protection

Despite its small footprint—weighing approximately 6 ounces—the 115PP is built to withstand harsh conditions. The enclosure meets NEMA 4 standards for watertight protection and NEMA 13 standards for oil and coolant tightness. This makes the switch suitable for a wide range of applications, from machine tooling to hydraulic systems where exposure to fluids and moisture is common.
