2. Technical Specifications
2.1 Electrical Parameters
It adopts multi-core signal hybrid wiring structure, rated signal operating voltage DC0~5V, auxiliary power supply max rated voltage DC12V; built-in RS232 signal transmission circuit with standard baud rate up to 38400bps matching Sparc mainboard onboard serial port protocol.Whole cable applies full aluminum foil wrapping + dense braided copper mesh double shielding design, contact ESD protection reaches ±12kV, effectively suppress electromagnetic interference from cabinet internal inverter and power loop to avoid cursor drift or intermittent control failure during long-term continuous operation.
2.2 Mechanical & Environmental Parameters
Inner conductor is high-purity tinned copper stranded wire with cross-linked PE high-temperature resistant insulation layer; outer sheath is oil-proof, flame-retardant and anti-aging black modified industrial PVC. Total length follows OEM fixed dimension designed for standard WEStation cabinet wiring layout without field cutting.Rated continuous working ambient temperature: 0℃~+55℃ inside closed control cabinet; spare part storage temperature: -40℃~+85℃; applicable relative humidity 5%~95%RH under non-condensing environment. The product complies with UL flame retardant certification and CE EMC industrial electromagnetic compatibility standard.
2.3 Structural Advantages
Both ends adopt overmolded integrated sealed connectors to block dust and humid gas from invading internal terminal crimping position, preventing contact oxidation and poor signal connection; internal core wires are fixed by binding wrapping to reduce wire fatigue breakage caused by long-period cabinet mechanical vibration; integrated signal & power integrated layout simplifies cabinet internal wiring arrangement and shortens maintenance troubleshooting time.
3. Core Function
Transmit real-time positioning and operation control signal between VME workstation mainboard serial port and external operator trackball, realizing cursor movement, parameter selection and screen switching operation on DCS monitoring picture;
Deliver low-voltage auxiliary power from cabinet internal backplane to trackball peripheral, ensure continuous stable running of industrial trackball;
Restrain stray electromagnetic interference via full shielding structure to guarantee stable man-machine interactive control of WDPF operator station.
4. Supply Information
