Description

G 2.140 Magnetic Sensors for Position Monitoring of block cylinders and pneumatic swing clamps

Application
Magnetic sensors are used for position monitoring of block cylinders and pneumatic swing clamps of the following data sheets:

Block cylinders with aluminium or bronze housing B 1.554
Block cylinder with guide housing B 1.738
Pneumatic swing clamp J 7.202

Description / Function
Electronic magnetic sensors allow position monitoring of the pistons of cylinders with nonmagnetisable housings (aluminium or bronze).
An annular permanent magnet is fixed to the piston, and its magnetic field is detected by an electronic magnetic sensor.
The magnetic sensors are fixed outside in the lengthwise slots of the cylinder body. The switching points are adjustable by displacement of
the magnetic sensors in the lengthwise slots of the body.

Monitoring of several positions
In the two lengthwise slots of the cylinder body several sensors can be fixed (depending on the length of the slot or the stroke).
In one slot, the minimum distance between the switching points is 6 mm; with two slots it is 3 mm.

Technology

Influencing the magnetic field with adjacent, magnetisable components (e.g. steel parts)
In order to guarantee perfect functioning, it is recommended to maintain a distance of at least 25 to 30 mm between magnetic sensor and magnetisable components. The function is indeed possible with a smaller distance but this depends highly on the individual circumstances for fitting. Thus ordinary steel bolts can also normally be used for fastening the cylinder. In borderline cases, screws of non-magnetisable steel (e.g. VA screws) can cause an improvement in the magnetic field.

Influencing the magnetic field with adjacent magnetic sensors
If several cylinders with magnetic sensors are installed directly adjacent to one another, the magnetic sensors can have a reciprocal
influence and malfunctions occur. Troubles of functioning can occur. A magnetisable steel sheet can help, placed between the cylinders or magnetic sensors as a shield.

Electric connection
Electric connection is made as per traditional inductive proximity switches.
Up to four magnetic sensors can be connected in series.

Switching hysteresis of approx. 3 mm and path
This has to be considered already when adjusting the magnetic sensors. For static pistons, the magnetic sensor must always be pushed forward to the piston from the opposite direction.
Magnetic sensors with short path are available on request.
