4. Information on specific columns
The BB3 3-part telescopic actuator is the ideal choice for vertical lift of beds where
design and easy integration in the customer’s guidance ensures optimum freedom of
design.
The BB3 is a 3-part telescopic actuator designed to meet EN 1970 for care beds, which
demands an adjustment range from 350 mm up to 750 mm.
Reed-switch:
The Reed-switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the piston rod’s position as well as to control several actuators
running in parallel.
Your nearest LINAK dealer can inform you of the number of pulses per stroke length.
Regarding reed-switch connection, see Figure 6.10.
• The columns must be securely mounted before operation, no rotation must be possible
• The motor housing must be mounted uppermost.
Warning
Do only use the column within specified working limits.
The BL1 is a 3-part lifting column designed to be used for example in hospital beds,
nursing home beds, treatment chairs, couches and dental chairs.
The lifting column is compact and has a long stroke length. The 3-part guidance enables
an overlap between the individual profiles, which ensures a high degree of stability.
The lifting column has an open spindle actuator with a chain drive inside which is
practically noiseless.

Input/output specifications: dual Hall, digital positioning
Column with Dual Hall (BL141H) are equipped with two hall sensors, A and B and a spindle magnet. In this way you can have pulses from the
column when it moves.
The feedback system has a 8P magnet which gives 16 shifts in pulses per spindle turn.
