NoShok 300 Series Pressure Switch
The NOSHOK 300 Series Mechanical Compact Pressure Switch is a versatile and reliable solution for a wide range of industrial applications, including hydraulics, pneumatics, and tank monitoring. This switch features a durable zinc-nickel plated steel housing and utilizes proven diaphragm or piston sensing technology to provide exceptional repeatability and service life.
With a field-adjustable switching point and adjustable hysteresis (10-30% of the switch point), this SPDT (Single Pole Double Throw) switch offers precise control and flexibility. The micro-switch technology incorporates solid silver, self-cleaning contacts to ensure long-term dependability even in frequent-use environments.
Key Features:
Flexible Pressure Ranges: Available in various configurations from vacuum (-5 inHg to -28 inHg) up to high-pressure scales (450 psig to 4,600 psig).
Adjustable Hysteresis: Allows for fine-tuning of the reset point, typically between 10% and 30% of the set point.
Rugged Construction: Zinc-nickel plated steel housing provides excellent corrosion resistance and durability.
Precision Contacts: Features SPDT snap-action switching with self-cleaning silver contacts for superior electrical conductivity.
High Cycle Life: Rated for over 1,000,000 load cycles, making it suitable for high-frequency operations.
Environmental Protection: Rated IP65 (for Hirschmann connections) or IP67 (for M12 and other integral cable options).
