TELEMECANIQUE XMLA020A2S11 Electromechanical Pressure Switch

Overview

TELEMECANIQUE XMLA020A2S11 is a single threshold electromechanical pressure switch from the Nautilus XMLA XM series. TELEMECANIQUE XMLA020A2S11 detects pressure changes of compressed air, clean water and hydraulic oil, actuates SPDT changeover contact for pressure interlock, pump control and alarm signal output. This TELEMECANIQUE XMLA020A2S11 is widely stocked as spare pressure sensing unit for hydraulic and pneumatic automation assemblies.

Features

TELEMECANIQUE XMLA020A2S11 supports adjustable rising pressure setting from 1 bar to 20 bar and falling pressure setting from 0.6 bar to 19 bar with fixed differential. It has local scale window for visual setpoint reading and red manual reset button on top. XMLA020A2S11 adopts G1/4 female process connection, compatible with standard hydraulic and pneumatic piping. Electrical wiring uses screw clamp terminals and Pg13 cable gland for cable entry. The unit is rated for 5 million mechanical switching cycles, stable under continuous vibration and pressure fluctuation. This switch is CE, UL and CSA certified, follows IEC 60947-5-1 standard. It is designed for 24/7 continuous operation on hydraulic power packs, air compressor stations, water circulation systems and machine pressure protection circuits.

Principle

TELEMECANIQUE XMLA020A2S11 uses internal pressure sensing element to detect fluid pressure. This Electromechanical Pressure Switch pushes the mechanical actuator when pressure reaches the preset threshold, switching the SPDT contact state. The fixed differential prevents frequent contact chattering caused by small pressure fluctuation. The contact signal is sent to relay or PLC for pressure protection and alarm control.

Applications

TELEMECANIQUE XMLA020A2S11 is deployed in hydraulic power units, air compressor systems, cooling water circuits, injection molding machines and press equipment. It monitors low pressure protection, high pressure alarm and pump auto start stop. TELEMECANIQUE XMLA020A2S11 is stocked as spare pressure switch for fluid pressure control automation assemblies.
