Reedswitches
Discover the power of reed switches – also known as position or status sensorsÂ
This innovative technology tells you exactly whether your cylinder (piston) is extended or retracted, giving you complete control over your pneumatic systems.
Why reedswitches?Â
In comparison to Hall Effect sensors, they are not only more cost-effective, but they also offer an impressive lifetime of at least 10 to 15 million switches. Despite the many moving parts, reed switches can handle shock and vibration without any problems, ensuring unprecedented reliability.
In addition, these sensors are designed to deliver low current signals to your bus system or PLC, making them an indispensable link in your automated processes.Â
Optimise the performance of your reed switch by accurately positioning it
Magnets generate a powerful magnetic field, but this field is not uniform in strength everywhere. To ensure that your reed switch functions reliably, it is vital to locate the strongest magnetic field. This simple but essential procedure applies to all Reed Switches and Hall Effect switches.
By ensuring the correct positioning and optimal operation of these sensors, you can count on reliable and efficient operation of your pneumatic systems.
Steps
- Connect the Reed Switch in accordance with the maximum voltage, current and power. Use a ballast resistor if necessary.
- Set the cylinder in the correct position, not in all cases the piston will be against the end caps.
- Place the reedswitch in the groove and move it towards the magnet, put a mark once the red LED starts to light up.
- Now let the reedswitch come from the other side and put another mark as soon as the red LED starts lighting.
- You can see between the marks the total width of the available magnetic field. Put a dash in the middle and mount the reedswitch at this position.
Prevent entanglement and damage with proper cable guidance
In some situations, it is vital to guide the reed switch cable neatly and safely along the cylinder to prevent entanglement and damage. Thanks to our simple yet effective solution with Ø6mm tubing, you can now guide your reed switch's cable effortlessly and neatly.Â
Simply feed the cable through the conduit and press it into the specially designed recess in the cylinder profile. This clever and cost-effective tip will keep your pneumatic systems running smoothly and safely, without unnecessary complications.
Two thin reeds form a switch
A reed switch is an engineering marvel in a hermetically sealed glass tube, in which two thin metal blades (the reeds) play the role of a switch.
These metal reeds, electrically conductive and magnetisable, are located at minimum distance from each other, with an overlap forming the 'Normally Open' (NO) contact. When this switch is placed in a magnetic field, the reeds magnetise and become magnetic poles that attract each other, causing the switch to close thanks to the internal magnetic field. A guarantee of reliable and safe operation even under the most demanding conditions.
Our reed switches are not only robust, but also cost-efficient. With a lifetime of at least 10 to 15 million switches, they offer a durable and reliable solution for your switching needs.
Solid state switch: switch without moving parts
Solid-state switches, designed without moving parts, offer a durable and long-lasting solution for all your switching needs.
The advantage of a solid state sensor is its lifespan, making wear and tear a thing of the past. Unlike traditional switches, the solid state sensor offers an almost infinite lifetime, resulting in cost savings and reliable performance in your pneumatic applications.
Operation
The operation of the solid state sensor is as ingenious as it is reliable. Under the influence of a magnetic field, this sensor generates a voltage difference across its element when current passes through it. The stronger the magnetic field and the original current level, the greater this voltage difference becomes. This voltage difference acts as a measurement quantity and switch, allowing you to effortlessly detect the position of the permanent magnet in the cylinder piston.
When using our Solid State Sensor, you have the flexibility to choose between PNP or NPN circuitry, depending on your application. The direction of the magnetic field and the field lines determine the switching response of the sensor material, allowing you to select the desired switching option: conductive in the presence or absence of a magnetic field, similar to the NO or NC option in Reed Switches.
