Magnet-Schultz Memmingen X AP X044 K54 D11 Solenoid Coil 24V 50Hz 100%ED

Magnet-Schultz Memmingen X AP X044 K54 D11 Solenoid Coil 24V 50Hz 100%ED

This is a new old stock replacement solenoid coil made by Magnet-Schultz Memmingen (MSM) of Germany, model X AP X044 K54 D11. It is cross-referenced to Balzers part number B4150-735-BG and serves as a direct replacement coil for Balzers vacuum solenoid valve assemblies. The coil is rated for 24V AC at 50Hz with a 100% ED (continuous duty) rating, meaning it is designed for continuous energization without a required off cycle.

Applications

Solenoid coils like the Magnet-Schultz X AP X044 K54 D11 are the electromagnetic actuator component of solenoid valves — when energized, they generate a magnetic field that moves an internal plunger or armature to open or close a valve. Magnet-Schultz Memmingen has been a leading German manufacturer of solenoid coils and electromagnets since the mid-20th century, supplying OEM components to vacuum, pneumatic, and fluid-control equipment makers across Europe and globally. This coil was supplied to Balzers (now Pfeiffer Vacuum) for use in their vacuum system valve assemblies, where solenoid valves control gas flow and venting in high-vacuum deposition, coating, and analytical systems. Replacement coils of this type are commonly needed when the original coil burns out or fails while the valve body itself remains serviceable, making a correct-fit replacement coil a cost-effective repair rather than replacing the entire valve assembly. The 100% ED continuous-duty rating makes this coil suitable for applications where the valve must remain energized for extended periods without thermal risk.
