300H-3-2-145/435-112

Pressure Sensors Transducers Overview

The NOSHOK 300H-3-2-145/435-112 is a mechanical pressure switch from the 300 Series, designed for industrial applications. It features a steel housing and utilizes a 1/4 inch NPT pressure connection. The device operates within a pressure range of 145 to 435 psi. Electrically, it functions as a Single Pole Double Throw (SPDT) switch with solid silver, self-cleaning contacts. The unit includes a Weatherpack shroud with a 3-pin female connector interface.

Pressure Sensors Transducers Feature Summary

• Mechanical switching action utilizing solid silver self-cleaning contacts for reliable electrical performance
• Integrated Weatherpack shroud providing environmental protection via a 3-pin female connector
• Robust steel housing construction ensuring durability in industrial environments

Pressure Sensors Transducers Applications

• Industrial process control systems requiring pressure monitoring
• Hydraulic and pneumatic equipment protection circuits
• Compressor and pump motor overload protection

Pressure Sensors Transducers Procurement Notes

Verify that the required pressure range aligns with the specified 145 to 435 psi operational window. Confirm the system pressure does not exceed the maximum limit to prevent damage. Ensure the 1/4 inch NPT thread matches the existing piping configuration. Check compatibility with the 3-pin female Weatherpack connector interface for proper wiring integration into the control circuit.

Pressure Sensors Transducers Selection Notes

Select this model when a mechanical SPDT switch is required for medium-pressure applications. The steel housing offers robustness suitable for harsh conditions. The integrated Weatherpack shroud simplifies wiring connections while maintaining environmental sealing. This specific part number defines the exact pressure range and connector type, ensuring precise fitment for designated industrial machinery.

Pressure Sensors Transducers Part Context

This component belongs to the NOSHOK 300 Series, which comprises compact mechanical pressure switches. The series is characterized by adjustable set points and durable construction materials. The 300H variant specifically denotes the inclusion of a Weatherpack shroud, distinguishing it from standard models without protective connectors. This series targets general industrial automation and fluid power control markets.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes must match the 145-435 psi range, SPDT configuration, and 1/4 NPT connection. Verify housing material and connector type compatibility before installation.
