Specifications
Supplier part number: Rexroth - BOSCH
Name:Logic Elements (Rexroth - BOSCH). - Directional Control Function , Control Cover. - Type : LFA. - Nominal Size NS 25. - E : With Electrical Monitoring Of The Closed Position .
Description:The LFA..E control cover from Bosch Rexroth is designed for directional control functions with electrical monitoring of the closed position. It is typically used with a 2-way cartridge valve and provides a binary electrical feedback signal for safety and position verification functions. 🔧 Design and Function The E designation indicates a control cover with spool position monitoring, which uses an inductive position switch to directly monitor the closed position of the valve spool. This provides a reliable electrical signal that confirms the valve is in its safe, closed state . Key aspects of this design: No Dynamic Seals: The position switch operates without dynamic seals, contributing to a long life cycle and high reliability . M12 Connection: The electrical connection is typically via a 4-pole M12 connector, with standard 24 V DC PNP transistor outputs . Safety Application: The valve is suitable for safety-relevant controls but must be assembled and commissioned by trained specialists . 📋 Key Technical Specifications (NS 25) The following specifications apply to LFA25E cover variants: Specification Detail Type LFA25E (Control Cover) Function Directional Control with Electrical Spool Position Monitoring Nominal Size (NS) 25 (NG25) Component Series 7X Max. Operating Pressure 350 bar (for most variants) Mounting Standard DIN ISO 7368 / ISO 4401 Spool Monitoring Inductive position switch type QM / Q6 Voltage 24 V DC Output PNP transistor output, 400 mA Remote Control Port G 1/4 (for LFA25) This cover is the typical choice when reliable confirmation of the valve's closed position is required by the machine control system. If you need more specific details, such as the exact pin assignment or installation dimensions, please let me know.
