Festo MHE2-MS1H-3/2G-QS-4 196135 3/2 NC Solenoid Valve 10mm Width

Festo MHE2-MS1H-3/2G-QS-4 (196135) is an ultra‑compact, 3/2‑way normally closed (NC), monostable solenoid valve from the MHE2 series. Its 10 mm width is ideal for highly compact valve terminals and control cabinets where space is limited. The directly actuated poppet design with a mechanical spring provides fast response with switching times down to 1.7 ms. The valve features QS‑4 push‑in connectors (for 4 mm tubing) on all three ports and operates on a 24 V DC supply with integrated holding current reduction and spark suppression [8†L12-L14].

Applications:

• Pilot control for larger pneumatic valves and cylinders

• High‑speed pick‑and‑place systems, rotary indexing tables

System Integration:

• This valve belongs to the Festo MHE2 series of ultra‑narrow high‑speed valves.

• The QS‑4 quick‑push connectors (factory fitted) accept 4 mm OD polyurethane, nylon, or PTFE tubing (PUN, PAN, PEN series).

• Mounts directly to any flat surface via two through‑holes using M2 screws.

• For electrical connection, a suitable 2‑pin mating plug and power supply (24 V DC) must be provided by the user.
