Core Features Piston Actuator for Medium-Pressure Sensing: Functions as a robust micro pressure switch with a precision-machined stainless steel piston, engineered to monitor medium-pressure fluids and gases in compact systems. It operates across a 1–10 bar (14.5–145 psi) range with a differential (deadband) of 0.5–1.5 bar (7–22 psi), making it suitable for pneumatic tools, hydraulic control circuits, and industrial fluid handling systems. Adjustable Setpoints with Secure Locking: Equipped with a calibrated adjustment screw to set actuation pressure within the range, secured by a locking nut to prevent drift from vibration or accidental tampering. This ensures stable performance in high-vibration environments (e.g., machine tools, pumps) where pressure consistency is critical. Broad Fluid Compatibility: The stainless steel piston and brass pressure port ensure compatibility with non-corrosive liquids (e.g., water, mineral oils), compressed air, and inert gases, making it versatile for industrial automation, automotive systems, and light manufacturing. SPDT Contacts for Flexible Control: Features single-pole double-throw (SPDT) contacts (1 NO + 1 NC) rated for AC 250V (3A resistive) and DC 30V (1.5A resistive). This configuration supports: Triggering pressure alarms via the NO contact (e.g., in hydraulic system overpressure protection). Controlling small pumps or valves through the NC contact to maintain optimal pressure. Sending status signals to PLCs in automated fluid management systems. Compact, Durable Housing: Housed in a glass-reinforced thermoplastic housing (UL94 V-0) with a space-efficient footprint (30mm × 22mm × 20mm) and lightweight design (22g), suitable for installation in dense machinery or tight enclosures. Dust-Resistant Protection: Meets IP40 protection (IEC 60529) to shield internal components from dust and particulate matter, ensuring reliability in factory floors, automotive assembly lines, and material handling facilities. Simplified Installation: Designed for panel mounting via two M2.5 screws, with a 1/8-inch NPT female port for fluid connections. The terminal block uses screw-type connections accepting 0.5–1.5mm² solid/stranded wires, ensuring secure wiring in vibration-prone setups. Typical Applications The ALCO Switch MPS 203P is engineered for medium-pressure monitoring in compact industrial systems, with core use cases including: Pneumatic Tool Control: Installed in air compressor lines or pneumatic tool stations to monitor pressure, ensuring optimal performance and preventing damage from under/over-pressurization. Hydraulic Circuits: Used in small hydraulic systems (e.g., lift tables, clamping devices) to detect pressure levels, triggering safety shutdowns or pressure adjustments as needed. Automotive Sub-Systems: Integrated into vehicle test rigs or component manufacturing lines to monitor pressure in brake lines, fuel systems, or cooling circuits. Industrial Washing Equipment: Deployed in pressure washers or cleaning systems to maintain optimal operating pressure, ensuring effective cleaning while preventing hose or pump damage. Fluid Handling Machinery: Installed in small-scale pumps or dispensers (e.g., for lubricants, coolants) to monitor delivery pressure, ensuring consistent flow rates
