SOLH IS3000 piston-type mechanical pneumatic pressure switch is fully interchangeable with equivalent SMC models. Air pressure pushes the built-in piston to actuate a 1NO+1NC micro contact switch, with adjustable pressure range 0.1~0.7MPa, hysteresis ≤0.05MPa and repeatability ±0.05MPa. Die-cast aluminum housing reaches IP40 dustproof grade, equipped with top adjustment knob and graduated window for offline pressure setting without power supply. Standard port Rc1/4, optional NPT1/4 thread, IS3100 gasket mounting version and IS3010 micro-load variant dedicated for PLC, as well as indicator light optional model. Its solid piston mechanical structure delivers outstanding shock and vibration resistance, stable on vibratory feeders, knocking hammers and stamping machines without signal drift or false triggering common to digital electronic switches. Max contact load 1A allows direct driving of miniature solenoid valves or connection to PLC digital inputs, widely applied for main air source low-pressure protection, cylinder clamping position confirmation and pneumatic safety interlock for vibration equipment. It provides higher electrical load capacity than IS10 reed switches and better cost performance & vibration stability than ISE30A digital pressure switches.

SOLH IS10 non-contact reed tube pneumatic pressure switch is fully interchangeable with matching SMC air service unit accessories. It operates via air pressure driving a magnet-equipped piston to trigger the reed tube magnetically, featuring zero mechanical contact abrasion and no electric sparks, with far longer service life than IS3000 piston micro-contact switches. The adjustable pressure range covers 0.1~0.6 MPa and hysteresis is controlled under 0.08 MPa. A side graduated viewing window allows offline pressure calibration with a screwdriver without power supply. Two mounting types are available: IS10-01S with R1/8 inline thread, and clip-on IS10M which fastens directly onto AC FRL manifolds to save cabinet space. Rated contact load reaches 1A for AC/DC 100V, capable of directly driving miniature solenoid valves or connecting to PLC digital inputs. Miniature and lightweight, it serves as a cost-standard pressure monitor for main air low-pressure alarm, cylinder full-stroke confirmation and safety interlock of vibrator pneumatic circuits.

SOLH MQR multi-channel rotary union adopts metal non-contact gap sealing with ultra-low rotating torque of 0.003~0.50 N·m. Free of rubber sealing rings, it avoids sticking even after long static storage.
