SOLH RQ thin cylinder is interchangeable with SMC RQ/RDQ series. It adopts innovative ringless built-in air cushion structure with 3 times energy absorption capacity of CQ2 rubber buffer and 50% lower operating noise. The ultra-slim square barrel is 20% shorter than conventional air cushion thin cylinders, and mounting dimensions fit CQ2 and CQS for direct upgrade replacement. Variants cover non-magnetic RQ, magnet-equipped RDQ and lockable RLQ for vertical load anti-drop. Suitable for continuous high-speed reciprocation at 50~500mm/s. Bore sizes φ20~100mm and supports oil-free operation. Widely used in high-cycle automation loading/unloading, precision clamping and positioning requiring low impact and low noise.

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 VNB201 external air pilot operated 2-way fluid valve is driven by 0.25–0.7MPa pilot air to realize zero differential pressure startup, performing stable switching under vacuum, low pressure and zero pressure difference. Adopting balanced poppet structure, it features low flow resistance, high flow capacity and bidirectional fluid passage for flexible pipeline layout. Valve bodies are available in brass, stainless steel and aluminum alloy, matched with NBR/FKM/EPR seals to suit compressed air, water, oil, vacuum, inert gas and mild acid/alkaline fluids. Without built-in electric parts, it generates no electric sparks and fits explosion-prone environments. Mountable at any angle with port sizes ranging from 3/8" to 1", it is widely applied in cooling water, lubricant oil, vacuum handling, chemical, food, pharmaceutical and flammable fluid pipeline on-off control.

A Switchgear Drawer Microswitch is a vital component in the operation and safety of electrical switchgear systems. Designed for precision and reliability, this microswitch is typically installed within the switchgear drawer mechanism to detect and signal the position of the drawer—whether it is fully inserted, withdrawn, or in an intermediate position. The microswitch operates by actuating when the drawer moves, sending an electrical signal that can control various interlocking and safety functions.
