HPS-500-G Pressure Switch

HPS-500-G Pressure Switch

Product catalog summary

Overview: The HPS-500-G Pressure Switch series is designed for high sensitivity pressure, vacuum, and differential switching. It is suitable for OEM applications due to its miniature size and offers a wide range of form factors for flexible installation. The switches are factory set or adjustable and are known for their long life and high reliability.

Specifications:

Switch Type: Single pole, single throw, normally open (normally closed available upon request).
Contact Voltage: Maximum 30 V AC/DC, 120 VAC for neon lamp load.
Current Rating: Maximum 40 mA resistive DC.
Contact Resistance: 1Ω or less at 150% of actuation pressure.
Material: Glass-filled polyester case with a urethane diaphragm (Teflon diaphragm for Range "A").
Mechanical Life: 20 million cycles.
Temperature Range: +4°C to +65°C, with potential setpoint deviation. Extended range available upon request.

Pressure Ranges and Tolerances:

Range A: 0.25 to 1.25 mbar, ±0.25 mbar tolerance, 12 mbar proof pressure.
Range B: 1.25 to 5.0 mbar, ±0.50 mbar tolerance, 37 mbar proof pressure.
Range C: 5 to 25 mbar, ±1.25 mbar tolerance, 174 mbar proof pressure.
Range D: 25 to 75 mbar, ±10% tolerance, 623 mbar proof pressure.
Range E: 75 to 374 mbar, ±10% tolerance, 1.4 bar proof pressure.
Range F: 374 to 1370 mbar, ±10% tolerance, 1.7 bar proof pressure.

Form Factors: The HPS-500 series is available in multiple form factors (Form 1 to Form 4) to accommodate various installation requirements. Each form factor has specific dimensions and terminal configurations.

Installation and Adjustment: The switches feature an adjustment screw for setting the actuation point, which is electrically active. Turning the screw clockwise decreases the actuation point, while counterclockwise increases it.
