SOLH PB1011A miniature diaphragm pump is fully interchangeable with equivalent SMC PB1011 models. The integrated built-in DC24V 3-port solenoid valve enables direct electric control, while PB1013A air pilot variant is designed for external equipment interlock. Shaftless-seal construction eliminates medium leakage entirely. Wetted components are optional PP polypropylene or SUS316 stainless steel, paired with composite PTFE diaphragms and FKM seals for excellent resistance to weak acid, alkali and organic solvents. It delivers adjustable flow from 8 to 2000 mL/min, handles liquid viscosity up to 100 mPa·s with maximum 2.5 m dry suction lift, operates below 64 dB(A) noise and achieves 30 million cycle diaphragm service life. Fluid ports adopt standard Rc1/8 thread with optional NPT1/8; air supply & exhaust ports use M5 miniature threads. Installation requires liquid outlet facing upward to avoid air lock. Widely used for micro chemical liquid transfer in semiconductor & PV lines, medical biochemical reagent feeding, printing ink & glue supply, and precise chemical dosing for environmental water treatment equipment.

SOLH MRHQ vane-type integrated rotary gripper is fully interchangeable with equivalent SMC models. It integrates a vane rotary module and parallel air gripper into a single actuator, replacing split combination of rotary table plus separate finger cylinder. Overall length is shortened by roughly 20% and tubing drag interference during rotation is eliminated. Bore sizes cover 10/16/20/25 mm with standard 90° and 180° rotation versions. End stop screws enable ±10° total angular fine adjustment. The double-acting parallel jaw achieves repeat positioning accuracy of ±0.01 mm. Five mounting surfaces together with locating bosses and pin holes enable fast centering and multi-orientation assembly. Built-in magnetic rings support up to four M9 series reed switches to detect both rotary limits and jaw open/closed status for full PLC interlock control. Adopting oil-free self-lubricating structure, it is widely used for workpiece gripping, flipping and direction conversion in confined-space 3C electronics and packaging automation lines for light & medium loads from 0.1 to 5 kg. A minimum 30% safety margin is required during load selection.

The Electrical Panel Indicator is a vital component in industrial and commercial electrical panels, designed to provide clear, real-time visual indications of operational status. Constructed from high-quality, durable materials, this indicator is built to withstand harsh environmental conditions and ensure long-term reliability.

Roof seal strip The IP31 Roof Joint is a robust and highly reliable component designed for use in electrical switchgear installations. With an ingress protection rating of IP31, this joint ensures a high level of protection against dust and condensation, making it suitable for various environmental conditions.

Electrical Switchgear Spacers are essential components designed to maintain precise alignment and spacing within electrical switchgear assemblies. These spacers play a critical role in ensuring the proper functioning and safety of electrical systems by providing necessary insulation and mechanical support between various switchgear parts.

SOLH CQS compact thin cylinder is dimensionally interchangeable with SMC CQS series and upgraded from CQ2 series. The square ultra-slim body features shorter overall length for high-precision short-stroke tasks in confined space. Variants include standard single rod, CQSW twin rod, CQSK non-rotating rod and XB24 long-life model. CDQS with built-in magnet supports multi-side mounting of magnetic switches. Equipped with low-friction oil-storage seal for oil-free operation and service life up to 5 million cycles, paired with fixed rubber buffers on both ends. Bore sizes φ12~25mm, widely used for pushing, clamping and positioning on precision fixtures of semiconductor and 3C electronics equipment for retrofitting and replacement.
