In combination with the safety controller, safety sensor technology from PSEN gives you the protection you covered! . Contactless magnetic safety switch PSENmag Magnetic switches can be used to monitor the position of mobile guards and are also suitable for difficult to precisely guide doors, which are susceptible to strong shocks.

1. The structure/working principle of the two is different Mechanical relays consist of an iron core, coils, and contacts. When the coil is energized, the current in the coil generates a magnetic field that makes the contacts act, thus completing the working principle of the mechanical relay. Solid state relays are made up entirely of electronic components. That...

Safety relays from PNOZ – a classic In 1987, Pilz was a milestone in the development of the world's first emergency stop safety relay to protect people and machines. PNOZ has also become synonymous with safety relays and is used by customers all over the world. The full range ...

For the monitoring of safe protected areas under harsh conditions, such as dust, dirt, rain, light, sparks or shocks, the safety radar sensor PSENradar in combination with the configurable small controller PNOZmulti 2 offers the best solution: in addition to outdoor applications as well as woodworking and ...

1. Replace small contactors: the contacts of the central relay have a certain ability to carry load, and when the load capacity is relatively small, it can be used to replace the use of small contactors, such as electric roller shutters and the control of some small household appliances. This not only serves the purpose of control, but also saves space, ...

The development of IT technology is changing all walks of life, automation is no exception, the degree of networking of production equipment and the use of standard protocols such as Ethernet for physical transmission of data has greatly increased, standardized protocols such as OPC UA allow access to controllers through IT systems, making data communication changeable.

Visualization solution PASvisu with OPC UA interface Pilz is expanding its web-based visualisation solution PASvisu: From the new version 1.3 onwards, the OPC UA interface can be connected to the small controller PNOZmulti and other control systems. Use...

1. The difference between the structure of current relay and voltage relay The main thing is that the coils are different. The coil of the current relay is connected in series with the load to reflect the load current, so its coil turns are small and the wire is thick, so that the voltage drop when passing through the current is very small, and it will not affect the load circuit.

Pilz safety relays, safety laser scanners, pilz modules, PSEN safety switches, encoders and safety gate gratings are the characteristics of pilz safety door switches in Germany. The safety gate switch is composed of two independent parts: the switch body and the operating part of the switch. ...

1. Physical location of the installation – "out of reach or out of sight" Consider installing the component in a place that is out of the reach of personnel, or directly outside the interlock switch as a protective cover to prevent disassembly or movement, as shown in the figure, whether it is a mechanical interlock on the left, or a non-...

First, the contact is loose and cracks The contact is the electrical touch part of the relay to complete the switching load, and the contact of some products is riveted and pressed, and its primary disadvantage is that the contact is loose, the contact cracking or the scale azimuth error is too large. This will affect the touch reliability of the relay. ...

1. When the load exceeds the action current, the circuit will be automatically cut off; 2. After the circuit is automatically cut off, the panel indicator light is on, which is convenient for the judgment of the fault part; 3. After troubleshooting, press the red button at the bottom of the panel to restore the normal power supply; 4. For other reasons, the shell ...

1. The effect is not the same: The primary effect of the relay is: signal detection, transmission, conversion or disposal, the circuit current it is on and off is generally small, and it is generally used in the control circuit to control weak signals. The primary effect of the contactor is to turn on or off the main circuit. Host...

1. First, unscrew out the fixing screws of fixing the noodle frame and the water baffle plate according to the above steps; 2. Unscrew out the two screws that fix the safety switch, and pull out the two lead pins connecting the safety switch; 3. Replace the new safety switch and assemble it according to the original steps. Electrical safety switch ...

Safety doors are mainly used to prevent the operation of the machine under certain conditions (usually when the guard is not closed) in order to avoid the occurrence of danger as much as possible. If the safety gate switch itself is not installed in compliance, resulting in its interlocking function not being implemented correctly, "it is time to do nothing", obviously ...

When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the electrical appliances that make the output circuit to be controlled on or off can be divided into two categories: electrical quantity (such as current, voltage, frequency, power, etc.) relays and non-electric (such as temperature, pressure, speed, etc.) relays.

1. Determine whether the safety relay itself is faulty: 1. Separate from the three circuits of short-circuit S10/S12, S11/S12, S21/S22. 2. Turn on the 24V power supply (A1 is positive, A2 is negative), and the Power light should be on at this moment; 3. Reset the S33/S34 terminals, and the K1 and K2 lamps ...

Why can't ordinary relays be used in safety-related applications? Ordinary relays use the mechanical action of coils and metal contacts to switch loads. Metal contacts may be fusion welded due to repeated operations. Once this happens, the machine will also be ...

1. Classification by use In terms of use, the classification of relays can be divided into two types: control relays and protection relays. In the meantime: thermal relays, overcurrent relays, and undervoltage relays are all protective relays. And moment relays, speed relays, intermediate relays ...

PILZ SAFETY RELAYS GENERALLY CONSIST OF AN IRON CORE, COILS, ARMATURES, CONTACT REEDS, ETC. As long as a certain voltage is added to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will overcome the tensile force of the return spring under the action of electromagnetic force attraction to ...

1. Control wiring: You think of it as a DC relay. 3. 7 is used to connect to 12V control voltage; 2. 7 is used to connect to 24V control voltage. In the meantime, 7 is used as the negative electrode of direct current, and it is connected to the neutral line when used. 2. Connect to the front of 220V. Second, the operation control: although the control voltage is connected ...
