8151-PL1-B Barksdale 350bar 250VAC/DC Piston Pressure Switch

Description

The Barksdale 8151-PL1-B is a high-performance Series 8000 piston-actuated pressure switch engineered for demanding hydraulic systems requiring precise setpoint control between 50bar and 350bar. This compact unit features a robust aluminium diecast housing and a chemically nickel-plated steel piston, ensuring long-term durability under high-cycle conditions. It is rated for a maximum system pressure of 600bar and utilizes SPDT silver microswitch contacts for reliable electrical switching up to 250V. The integrated NBR seals and PTFE-bronze piston sealing provide excellent chemical compatibility and low friction, while the IP65-rated DIN EN 175301-803A cube plug ensures secure electrical termination in industrial environments.
