Core Features
Piston Design for Neutral Gas Sensing: Functions as a precision micro pressure switch with a stainless steel piston actuator, engineered to monitor pressure in neutral gas systems across a 1–15 bar (14.5–217.5 psi) range. This robust design balances sensitivity with durability, making it ideal for compressed air systems, inert gas handling, and industrial pneumatic control.
Fixed Setpoint with Reliable Hysteresis: Pre-calibrated to actuate at a fixed pressure (configurable at 2, 5, or 10 bar during ordering) with a built-in differential (hysteresis) of 0.5–1.5 bar (7–22 psi), preventing rapid cycling in fluctuating systems. This stability ensures consistent performance in applications like air compressor monitoring or gas cylinder pressure control.
Broad Gas Compatibility: The 304 stainless steel piston and brass pressure port ensure compatibility with compressed air, nitrogen, argon, and other non-corrosive gases, making it versatile for factory automation, laboratory equipment, and gas distribution systems.
SPDT Contacts for Flexible Control: Features single-pole double-throw (SPDT) contacts (1 NO + 1 NC) rated for AC 250V (2A resistive) and DC 30V (1A resistive). This configuration supports:
Triggering low-pressure alarms in pneumatic systems (e.g., via the NO contact).
Controlling small valves or compressors through the NC contact to maintain optimal pressure.
Sending status signals to PLCs in automated gas management systems.
Ultra-Compact Housing: Housed in a glass-reinforced thermoplastic housing (UL94 V-0) with a diminutive footprint (32mm × 22mm × 19mm) and lightweight design (20g), suitable for installation in dense machinery or tight enclosures where space is critical.
Dust-Resistant Protection: Meets IP40 protection (IEC 60529) to shield internal components from dust and particulate matter, ensuring reliability in factory floors, electronics manufacturing facilities, and workshop environments.
Simplified Installation: Designed for panel mounting via two M2.5 screws, with a 1/8-inch NPT female port for gas 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 MPN206N is engineered for neutral gas pressure monitoring in compact industrial systems, with core use cases including:
Compressed Air Systems: Installed in small air compressors or pneumatic tool stations to monitor line pressure, ensuring optimal performance and preventing damage from under/over-pressurization.
Inert Gas Handling: Used in laboratory or manufacturing systems distributing nitrogen or argon, providing pressure monitoring to maintain consistent flow rates for processes like welding or sample preservation.
Pneumatic Automation: Integrated into small-scale pneumatic circuits (e.g., in electronics assembly) to regulate pressure for actuators, grippers, or valves, ensuring precise motion control.
Gas Cylinder Monitoring: Deployed in medical or industrial gas cylinder storage to detect low pressure, triggering refill alerts before supply depletion.
Packaging Machinery: Used in modified atmosphere packaging (MAP) systems to monitor gas pressure during sealing, ensuring proper preservation of food or pharmaceutical products.
