Barksdale 96211-BB4-T2 Compact Pressure Switch 25-125 Psi

Product Description

The BARKSDALE 96211-BB4-T2 is a compact pressure switch designed for use in industrial and mechanical systems where reliable pressure-activated switching is required. It monitors system pressure and triggers an SPDT (single-pole, double-throw) contact when pressure rises or falls within its adjustable setpoint range of 25 to 125 psi. The switch connects via a 1/4 inch NPT male thread and uses a DIN 43650 electrical connection. With a 2% repeatability rating and a brass wetted material construction, this switch suits applications where consistent actuation and corrosion resistance matter. Licensed HVAC technicians, pipefitters, and industrial maintenance professionals are the typical installers.

This pressure switch fits residential and light commercial mechanical systems that require pressure-based control logic, including HVAC, compressed air, hydraulic, and fluid handling applications. The adjustable setpoint range makes it adaptable across a variety of system pressure requirements. The switch operates in both normally open and normally closed configurations, allowing flexibility in control circuit design. It is rated for use at temperatures from -20 degrees F to 165 degrees F, making it suitable for indoor and outdoor installations in moderate climate conditions.

Key Features

• Adjustable pressure setpoint range: 25 to 125 psi on rise, 22.5 to 112 psi on fall
• SPDT contact form supports both normally open and normally closed circuit configurations
• Brass wetted components and BUNA-N O-ring provide fluid compatibility and durability
• DIN 43650 electrical connection for secure, standard industrial wiring interface
• 2% repeatability for consistent, predictable switching performance
• CSA listed and UL Recognized Component (UR) for code-compliance in commercial and industrial installs

Compatibility

Designed as an OEM-style replacement compact pressure switch for industrial, HVAC, and fluid system applications requiring a 1/4 inch NPT male threaded pressure port and DIN 43650 electrical connection.

Installation Notes

Installation should be performed by a licensed technician or qualified trade professional. Always depressurize and de-energize the system completely before removing the existing switch or installing the new unit. Use appropriate thread sealant on the NPT connection and verify the torque is appropriate for the fitting material to avoid damage to the brass body. Confirm the control circuit voltage and amperage do not exceed the switch ratings before restoring power.
