IS3000 Series Mechanical Micro Pneumatic Pressure Switch

Brand: SOLH by Richge Technology

Product Positioning

     SOLH IS3000 series is a classic piston-driven mechanical micro pressure switch. It pushes an internal micro contact switch via air pressure acting on a spring piston, delivering robust direct electrical output. Mainly used for air circuit over/under pressure protection and automatic trigger control, same grade & compatible replacement as IS10 reed switch series. Perfect for heavy vibration environments where electronic digital switches are unstable.

Working Principle & Core Structure

  1. Operating Principle

     -- Compressed air pushes the spring-loaded piston; once air pressure reaches the preset threshold, the piston mechanically actuates the built-in micro switch to open or close the contact circuit. When pressure drops below hysteresis value, the spring resets the piston and restores the original switch state.

  2. Core Structural Components

     -- Top pressure adjustment knob: Direct rotary setting of trigger pressure without power supply

     -- Built-in 1ab micro switch: Universal AC/DC load, directly connect PLC input terminals or drive small solenoid valves

     -- Graduated pressure viewing window: Visible MPa scale for real-time preset pressure reading

     -- Die-cast aluminum housing: IP40 dust protection, suitable for general factory workshop environments

Complete Model Coding & Variant Explanation

  1. Model Example: IS3000-02-P

     -- IS3000: Base standard threaded body series

     -- 02: Port thread code = Rc1/4; suffix N02 = NPT1/4 American thread

     -- P: Built-in neon indicator light (blank = standard model without light)

  2. Derivative Special Models

     -- IS3100: Gasket surface mounting variant, matched with modular air service units (AFC/AC series) for integrated manifold installation

     -- IS3010: Micro low-load dedicated model, optimized for tiny DC signal input of PLC controllers

Key Product Advantages

  1. Shock & Vibration Resistant Heavy-Duty Mechanical Design

     -- Solid piston + micro contact construction, stable performance under continuous vibration from vibrators, knocking hammers and stamping equipment, no signal drift or false triggering.

  2. Simple On-Site Calibration Without Power

     -- Top rotary adjustment knob + visible graduated window; pressure threshold can be set offline without energizing the control cabinet.

  3. Wide AC/DC Load Compatibility

     -- High 1A contact load capacity allows direct driving small solenoid valves without intermediate relays, or direct connection to digital PLC input points.

  4. Ultra-Low Hysteresis

     -- Max dead band ≤0.05MPa, consistent trigger & reset pressure to avoid frequent rapid on-off cycling of downstream equipment.

Matching Typical Industrial Application Scenarios

  1. Main Air Source Low Pressure Protection

     -- Installed downstream of air filter regulator lubricator units; triggers alarm signal if supply pressure drops below 0.4MPa to protect K/GT vibrators, BVP/SK knocking hammers and pneumatic actuators from insufficient thrust damage.

  2. Cylinder Stroke Position Confirmation

     -- After cylinder fully extends, chamber pressure rises to preset value to send switch signal for interlocking the next production process step.

  3. Vibrator Circuit Safety Interlock

     -- Monitors operating air pressure; cuts power to XQ quick exhaust valves when pressure falls below threshold to prevent vibrator burnout caused by under-pressure operation.
