System Architecture & Signal Flow
The SEC-4400MC operates as a closed-loop pressure controller within a process gas or vacuum system. A pressure transducer (upstream or downstream) feeds real-time pressure data to the controller’s signal conditioning stage. The SEC-4400MC compares this measured value against the operator-defined setpoint and drives a proportional control valve or throttle valve to maintain the target pressure. The LF-K variant integrates lead-free solder joints throughout the PCB assembly, ensuring compliance without compromising signal integrity or thermal performance.
Typical signal flow: Setpoint Input → PID Control Loop → Valve Drive Output → Process Chamber → Pressure Transducer Feedback → SEC-4400MC Input

Technical FAQ
Q: Is PCA-28224 LF-K the same as 00433266?
A: Yes. These are cross-reference part numbers for the same MKS SEC-4400MC unit used across different OEM system builds. Konmask verifies equivalency before shipment.
Q: What does the “LF-K” suffix indicate?
A: “LF” denotes Lead-Free (RoHS-compliant solder), and “K” is an MKS internal revision/configuration designator. This variant is suitable for facilities with environmental compliance requirements.
Q: Can this replace a standard SEC-4400 (non-MC)?
A: In most configurations, yes. The SEC-4400MC is the enhanced successor. Confirm connector pinout and control interface compatibility with your system documentation before installation.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days. For sourced units, lead time is typically 2–4 weeks. Contact us for current availability.
Q: Do you provide warranty?
A: Yes. Konmask provides a 90-day functional warranty on all tested units. Extended warranty options available for volume orders.
