Tubular Solenoids DC (Available in High Volumes only)

Dialight specialise in solenoid design. The tubular solenoids consists of a coil with an associated iron circuit forming the fixed part. The difference from the standard solenoid being that the coil is fully enclosed in a high permeable steel tubular case to improve efficiency by minimising flux leakage. A moving iron plunger is pulled into this coil when it is energised.

Pull and Push

Both pull and push are available as standard. The pull action is converted to a push action by fitting a suitable thrust pin

Isolated Washer

The tubular solenoid uses an isolating washer between the plunger and E-ring. This is to prevent the plunger and body from any mechanical contact, which would cause residual magnetism, causing the plunger to 'stick' in the energised position when the power is off.

Voltage

The tubular solenoid range is only available as a DC operated solenoid.
6, 12, 24, 48V DC are standard.

Wattage - Temperature

All units given for tubular solenoids are designed on the basis of a maximum allowable input wattage without exceeding 120ºC coil temperature when operated at the rated duty cycle in a 20ºC ambient temperature.

Force / Stroke

When a solenoid is fully opened it has a large air gap. The reluctance of this air gap keeps the magnetic field small and the force correspondingly low. As the plunger closes, this reluctance falls and the magnetic field increases. For this reason, the force obtainable from a solenoid increases as the plunger closes.
The tubular solenoid is designed for longer strokes and higher forces than standard solenoids. This is due to the coil being fully enclosed with the steel casing so minimising magnetic flux leakage and maximising the magnetic field.
