Huatong lists cylinder position switches, switch-mounting accessories, exhaust silencers and tubing products. These items are specified by interface and service conditions so they match the pneumatic circuit or cylinder on which they are installed.
Models and selection data
| Model or series | Published configuration or function | Selection details |
|---|---|---|
| DX-72 / DX-50 / DX-40 / DX-35 | Magnetic cylinder switch families | Match the cylinder, sensor mounting and electrical interface. |
| DX-32 / DX-31 / DX-21 / DX-20 / DX-16 | Additional magnetic switch families | Confirm voltage, output type, wiring, cable length and connector for the exact version. |
| PI / PM / PAC / PN / PBN / BK | Steel mounting bands | Match the cylinder body diameter, switch style and available installation space. |
| KXY | Sintered exhaust silencer family | Match the exhaust thread, flow and permitted backpressure. |
| CL | Coiled hose family | Specify material, tube outside diameter, usable reach and the end connection. |
Switch and bracket selection
Check the cylinder for a magnetic piston and identify its switch groove or band mount. Compare the selected switch output to the control input, including supply voltage, current and wiring arrangement. Confirm the sensing location at both ends of the required stroke.
Exhaust and tubing selection
A silencer can affect exhaust backpressure and actuator cycle time. Include the expected exhaust flow when sizing it. For coiled tubing, allow movement throughout the full travel and confirm that the tube and fitting share the same outside diameter and compatible material.
