The Dropsa 1655 series is a piston-operated micro-switch specifically engineered for monitoring lubricant flow in dual-line centralized lubrication systems. It is designed to ensure the correct delivery of lubricant to critical friction points, such as bearings and gears, thereby preventing equipment failure due to inadequate lubrication.

Key Features

• Lubrication System Integration: The 1655 series is purpose-built for use with Dropsa dual-line lubrication systems, including AP6, AG6, DMM, DM, DMG, DMG1, and DMG2 series feeders. It verifies piston movement in both directions, confirming that lubricant has reached the intended point.
• Robust Construction: Designed for industrial environments with a protection rating of IP55, offering resistance to dust and water jets. The switch operates reliably in temperatures ranging from -15°C to +80°C.
• High Pressure Capability: The switch can withstand system pressures up to 200 bar (2900 psi), making it suitable for high-pressure lubrication applications.
• Electrical Specifications: Features a high electrical rating of up to 10A at 250V AC, providing flexibility for integration into various control circuits and PLCs.
• Dual Installation Requirement: To monitor the complete cycle of the distributor piston, a micro-switch must be installed on both sides of the feeder block. This dual-switch configuration ensures that the lubricant delivery is verified for both directions of piston movement.

Applications

The 1655 series is primarily used in industrial machinery equipped with dual-line lubrication systems. Typical applications include steel mills, heavy-duty presses, mining equipment, and any large-scale industrial machinery where reliable, automated lubrication is critical for operational uptime and component longevity.
