IS10 Series Reed Tube Mechanical Pressure Switch 

Brand: SOLH by Richge Technology 

Product Positioning

     SOLH IS10 series is non-contact reed tube (dry reed) mechanical pressure switch, basic pressure monitoring component for standard pneumatic circuits. Featuring simple compact structure and ultra-reliable long-cycle performance, it is widely matched with FRL air filter regulator lubricator three-units for real-time air pressure detection and interlock signal output.

Working Principle & Internal Core Structure

  1. Operating Principle

     -- Compressed air pushes piston against spring tension, the built-in magnet on piston moves close to reed tube to complete magnetic trigger and circuit conduction. When air pressure drops below reset threshold, spring pushes piston back, magnet moves away from reed tube and circuit cuts off.

  2. Core Structural Parts

     -- Piston with integrated permanent magnet: Senses air pressure displacement

     -- Reed tube (dry reed switch): Non-contact magnetic actuation, zero mechanical contact abrasion

     -- Pressure adjustment screw: Manual set trigger threshold with screwdriver

     -- Mechanical graduated viewing window: Direct readout of preset pressure value in MPa unit

Standard Core Technical Specification Table

Full Series Model & Two Mounting Styles

Two mainstream installation structures for different layout demands:

  1. Inline Thread Mount Type (IS10-01S)

     -- Direct screw installation via R1/8 thread port, compatible with single cylinder, solenoid valve outlet and mini individual air service units.

  2. Manifold Base Mount Type (IS10M / IS10E)

     -- IS10M equipped with square clamping base on side, can be directly clipped onto SMC standard AC modular FRL three-units without extra adapter fittings, saving cabinet internal installation space.

Core Product Competitive Advantages

  1. Zero mechanical contact wear

     -- Non-contact magnetic reed triggering, no electric spark at contact point; service life 5~10 times longer than traditional mechanical micro-contact pressure switches such as IS3000.

  2. Intuitive offline pressure calibration

     -- Side built-in MPa graduated scale window, adjust setting screw with screwdriver; pressure threshold can be set without power supply on site.

  3. Universal AC & DC load compatibility

     -- Supports all AC/DC voltage below 100V, can directly drive miniature solenoid valves or connect digital input terminals of PLC without intermediate relay.

  4. Miniature lightweight compact design

     -- 16% lighter and 11% smaller volume than old-generation IS1000 series, perfectly fits highly integrated narrow automated equipment layout.

Matching Typical Industrial Application Scenarios

  1. Main air source low-pressure monitoring & alarm

     -- Installed at outlet of FRL three-units; sends interlock alarm signal once supply pressure falls below 0.4MPa to protect pneumatic vibrators and knocking hammers from insufficient thrust damage.

  2. Cylinder full-stroke position confirmation

     -- When cylinder fully extends, chamber pressure rises to preset value to output trigger signal for sequential interlock of next production station action.

  3. Vibrator circuit safety protection

     -- Real-time monitor working air pressure; cut off power supply of quick exhaust valve when pressure is lower than threshold, avoid vibrator burnout caused by weak vibration force.

One Sentence Summary

     SOLH IS10 series non-contact reed tube pressure switch offers inline thread mount and FRL manifold clip-on variants, with 0.1~0.6MPa adjustable range, 5 million long cycle service life and offline pressure calibration, ideal low-cost compact air pressure monitoring sensor for cylinder, vibrator and general automation pneumatic circuits.
