    Pressure Switches

    PBN1 Series

    1 in-H2O to 50 in-H2O. SPNO. Senses air. Gage, vacuum, differential. Life: up to 20 million cycles. 8 psi or 15 psi proof pressure.

    Overview

    The Honeywell PBN Series is a range of versatile, low-cost, ultra-low pressure switches and sensors. PBN products are compact, lightweight, feature high reliability, and are designed to yield a repeatable response over millions of cycles. They can be mounted in virtually any orientation and their rugged construction allows use in the most rigorous environments.

    The PBN1 Series has a direct-action blade contact with a set-point range of 0.018 psi to 1.8 psi and gold contacts. The PBN3 Series features a snap-action switch with 0.036 psi to 40 psi and silver contacts.

    Product specifications such as operating characteristics, termination type and contact materials can be customized for certain applications.
