- Recommended Products
- Compact cylindrical body: Ø20 × 25 mm.
- Rear M6 mounting hole with a 12 mm depth callout in the source drawing.
- UL1007 26AWG leads, with a nominal length of 200 mm.
- Separate H2025-12A51 and H2025-24A205 coil versions.
- Source specification distinguishes continuous and intermittent duty operation.
- Confirm the coil and supply. Identify the exact model and obtain the approved voltage and duty specification before powering the unit.
- Prepare the contact surface. Use a flat, clean ferromagnetic workpiece with good magnetic permeability. The source recommends a thickness greater than 3 mm and a contact area larger than the magnet holding face; these are selection guidelines, not a fully defined test condition.
- Control the air gap. Coatings, surface roughness, misalignment and debris create gaps that can reduce holding force. Test the actual material, thickness and contact area.
- Check the mounting. Use the rear M6 interface. Confirm usable thread engagement and tightening torque; the 12 mm depth callout must not be treated as an approved screw length.
- Validate thermal operation. Temperature affects coil resistance and performance. Confirm ambient temperature, mounting heat dissipation, duty cycle and maximum on-time; insulation class does not define ambient operating temperature.
- Verify release and controls. Test residual attraction and switching behavior with the actual workpiece. Have the control circuit and inductive-load suppression reviewed for the required release time.
H2025 Round Holding
Electromagnet
Compact 20 × 25 mm body with rear M6 mounting and 200 mm leads
Product Overview
The Landa H2025 is a round holding electromagnet with a 20 mm diameter and a 25 mm body length. Its circular pole face is intended to contact a suitable ferromagnetic workpiece in an electrically controlled holding assembly. The series specification lists H2025-12A51 and H2025-24A205 coil versions.
Selection requires review of the operating voltage, duty cycle, air gap, workpiece and thermal conditions. The source documents contain conflicting insulation and dielectric test ratings; these ratings require engineering approval before an order specification is finalized.

Electrical Performance
Source data for review, not a complete application rating. The series specification lists the following values at 25°C. The meaning of this temperature and the complete force-test setup remain to be confirmed.
| Listed duty cycle | Listed power at 25°C | Listed holding force at 25°C | Maximum on-time |
|---|---|---|---|
| 100% continuous | 2.8 W | 35 N | Continuous in the source table; installation thermal limits require confirmation. |
| 50% or less | 5 W | 45 N | 60 seconds; cycle and cooling conditions require confirmation. |
The specification also contains 16V and 32V entries. Their approved duty conditions have not been confirmed; they must not be used as supply recommendations. Do not apply the intermittent 45 N value to continuous operation.
The 24V drawing separately states F ≥ 3.5 “Kg” at a 0 mm gap and 24V DC. The force unit, acceptance criterion and relationship to the series table require clarification. No verified force-versus-gap or temperature-rise curve has been supplied.
Working Principle
Illustrative Application — Power OFF: Release. Release behavior requires application testing. AI-generated concept, not an actual installation or dimensional reference.
Electrical current in the coil produces a magnetic field at the holding face. A suitable ferromagnetic workpiece completes the magnetic path. This is an energized holding design; it is not specified as a permanent power-off holding electromagnet.
Power ON: Hold. Power OFF: Release. This operating principle was confirmed by the project owner on 22 October 2026. Removing power removes the energized holding field; actual release behavior and residual attraction require application testing. The 24V drawing includes a reference residual-magnetism entry without a complete test method. Release behavior must be evaluated with the actual workpiece and control circuit.
Applications
Illustrative Application — Power ON: Hold.
The H2025 may be evaluated for compact fixture holding, electrically controlled retention of ferromagnetic parts, and small automation assemblies where its size, contact geometry and verified release behavior meet the design requirements. These are potential applications, not documented customer installations.
Validate the required holding margin and failure behavior in the actual assembly. The listed holding force is not a rated working load for lifting equipment.
