MHE2-MS1H-5/2-M7 Festo Solenoid Valve

Model Identifier MHE2-MS1H-5/2-M7
Official Part Number 525113
GTIN Standard 4052568161163

Technical Overview

The Festo MHE2-MS1H-5/2-M7 is a high-performance, fast-switching 5/2-way monostable solenoid valve designed for ultra-high-speed industrial automation. Engineered with a pressure-relieved poppet design, this 10mm wide valve achieves switching frequencies up to 300 Hz with response times as low as 1.7 ms. It is optimized for applications requiring extreme precision, long service life, and high-frequency actuation, featuring integrated spark arresting and holding current reduction circuits for enhanced electrical efficiency and thermal management.

Key Features

  • Fast-switching poppet valve design
  • Pressure-relieved for high reliability
  • Integrated spark arresting and protective circuit
  • Holding current reduction for low power consumption
  • IP65 protection rating for industrial environments
  • Bipolar reverse polarity protection
  • Compact 10mm width for high-density mounting
  • Non-detenting manual override

Ultra-fast switching response times of 1.7 ms (Off) and 1.9 ms (On) combined with a 300 Hz maximum switching frequency, specifically designed for high-speed sorting and precision ejector applications.

Industrial INOSAKI Applications

1. High-Speed Automated Sorting

Used in conveyor-based sorting systems for the rapid ejection of defective or categorized items at high velocity.

Problem Solved

Standard solenoid valves lack the response time necessary for high-throughput lines, leading to missed targets; the MHE2 ensures sub-2ms precision for accurate sorting.

High-frequency switching300Hz actuationFast-response time

2. Precision Fluid and Material Dosing

Controls pneumatic dispensing heads in electronics and pharmaceutical packaging for consistent application of micro-volumes.

Problem Solved

Eliminates inconsistencies in air-burst timing that cause dosage variation, utilizing a pressure-relieved poppet design for repeatable pneumatic pulses.

3. High-Cycle Pilot Valve Control

Acts as a pilot stage for large-scale process valves in demanding environments like automotive assembly or textile manufacturing.

Problem Solved

Standard pilot valves fail under high-frequency thermal stress; integrated holding current reduction and spark arresting protect the valve during 100% duty cycles.
