Neodyn 182P NEMA 4X, 7, 9 and 13 Vacuum Switch

Description

ITT Neo-Dyn 182P series represents a robust solution for vacuum monitoring in sectors requiring strict safety standards. The core advantage of this device lies in its Nega-Rate® Belleville disc spring technology. Unlike traditional vacuum switches that may drift under vibration or thermal stress, this snap-action system ensures consistent performance and a long operational life.

This switch is housed in a rugged enclosure that meets multiple stringent standards, including NEMA 4X for corrosion protection and NEMA 7, 9, and 13 for hazardous locations involving explosive gases or dusts. The electrical assembly is a snap-action switch, fully listed by Underwriters’ Laboratories, Inc., FM Approval, and CSA International, guaranteeing compliance with global safety regulations.

Installation and maintenance are streamlined through a 1/2 NPT male conduit connection with pre-wired leads. While the unit allows for precise field calibration via an adjustment port, its design inherently protects the setting once the unit is mounted, ensuring process integrity is maintained without the need for additional locking mechanisms.
