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. FEATURES POTENTIAL APPLICATIONS Sensitive to ultra-low pressures Arc fault detection Gage, vacuum and differential measurement Filter restriction Miniature size Safety interlock Lightweight HVAC Fast response Vacuum control Rugged housings Liquid level sensing Shock and vibration resistant Pick and place machiner y Low and high current versions Pump control Counters Edge detection Traffic counters Motor controlPBN1 MECHANICAL SPECIFICATIONS Characteristic Measure Output SPST nor mally open Sensing medium Air Expected mechanical life Up to 20 million cycles depending on load Proof pressure 8 psi for units where set point is 3.0 in-H O or less 15 psi for units where 2 set point is greater than 3.0 in-H O 2 Weight Less than 10 grams Operating temperature 4 C to 66 C with Polyurethane (standard) diaphragm -40 C to 96 C with Teflon (optional) diaphragm Action pressure Tolerance 20 % for non-adjustable sensors except for PBN1XXXX-A which has a tolerance of +0 %/-100 % DESCRIPTION The PBN1 series is available in a wide range of actuation pressures. 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.
