Product Description

Designed for Extended Duty, Simple and Reliable

Series A6 Durable Pressure Switches have been specifically designed to stand up to extended duty applications. These switches are constructed with a polyimide film diaphragm and are compatible with a variety of fluids. For ease of installation, the switches come with a 1/4″ male NPT process connection and can be mounted in any orientation. The Series A6 pressure switches are compact and have great setpoint integrity, and feature simple, easy set-point field adjustment.
