PBN1B222-A Honeywell

PBN Series Pressure Switches and Sensors DESCRIPTION and their rugged construction allows use in the most rigorous The Honeywell PBN series is a range of versatile, low-cost, environments. ultra-low pressure switches and sensors. PBN products are compact, lightweight, feature high reliablity, Product specifications such as operating characteristics, and are designed to yield a repeatable response over millions termination type and contact materials can be customised for of cycles. They can be mounted in virtually any orientation certain applications.

The required pressure can be supplied factor y PHYSICAL SPECIFICATIONS set or as an adjustable unit. Smooth 4 mm diameter por ts Characteristic Measure perpendicular to the housing and 5 mm barbed radial ports Mounting 2,6 mm (No 4), thread size screws through mounting lugs or 2 mm (No 2) are available. Nominal actuation pressure varies from 1 in-H O 2 thread size screws through eyelets to 50 in-H O on factor y set models. Adjustable models have 2 Case material Polycarbonate standard actuation pressures which can be set up to 416 in-H O. 2 (other materials available upon request) Contact material Gold inlay 18 carat on phosphor bronze Diaphragm material Polyurethane (standard) Teflon (optional) FEATURES Electrical connections Ter minals: 4,8 x 0,5 mm tab-type Sensitive to ultra-low pressure (bifurcated) for use with female quick Gauge, vacuum and differential measurement disconnects (ref.
