Pilmagnetic switches – what are the properties of safety switches?

1. Contact failure (1) The phenomenon that cannot be disconnected due to mechanical occlusion of the contact (the needle-like protrusion and pit formed on the contact bite each other), fusion welding, or cold welding. (2) The contact wear of the relay is caused by the absence of arc extinguishing devices or measures, or improper parameter selection, ...

From May 4th to May 10th, Pilz will be showcasing how future-oriented automation technology can improve safety and productivity in the packaging industry at Interpack 2023 in Düsseldorf under the theme "Flexible automation solutions for industrial safety and security".

(1) Use The high-voltage load switch is an electrical appliance with a function between the high-voltage circuit breaker and the high-voltage isolation switch, and the high-voltage load switch is often used in series with the high-voltage fuse; It is used to control power transformers. The high-voltage load switch has a simple arc extinguishing device, because it can turn on and off ...

An autonomously running burner management system has a complex structure and must comply with many international standards. Due to the high level of danger, strict safety regulations need to be applied to avoid the presence of unburned fuel in the combustion chamber. Pilz has a safe burner management system specifically tailored to these requirements. ...

　　1. The same module can be triggered by high or low level through different wiring, and the trigger current is not less than 1mA, and the output capacity of the IO port of some 51 single-chip microcomputers is weak, and the circuit of pulling up or increasing the driving capacity is required (the default is low level triggering); 2. Advantages of low-level drive, ...

1. The shape is larger The dimensions of safety relays are different from ordinary relays, and safety relays are larger. 2. Modules instead of components A safety relay is a module, not an electronic component like a normal relay. 3. Color Quiet...

The most common ones are the following: (1) Contact failure 1. The phenomenon that cannot be disconnected due to mechanical occlusion of the contact (the needle-like protrusion formed on the contact and the pit biting each other), fusion welding, or cold welding. 2. Due to the contact resistance becoming large and unstable, the circuit cannot be normal ...

The main function of a thermal relay is to protect the motor. The new electronic thermal relay has protection against overload, overcurrent, blocked rotor and various phase faults, current unbalance, interphase short circuit, inter-turn short circuit or overvoltage, undervoltage and so on. In the process of using thermal relays, we should ...

The repair and maintenance of industrial field equipment is inevitable, and the most embarrassing thing for field personnel is that the equipment is started while the person is still in the danger area. In this scenario, personnel are highly vulnerable to serious injuries from moving parts, harmful gases, harmful rays, and high temperatures. Listing...

1. The switch binding post is generally marked with L, L1, L2. When the L end enters the line, L1 and L2 have one end and L on, and after pressing the switch, the other end of L1 and L2 is connected to L. 2. Peel the thread with diagonal pliers first, and be careful not to leave too long the thread to avoid touching. 3. To the left ...

1. Rated working voltage It refers to the voltage required by the coil when the relay is working normally. Depending on the model of the relay, it can be either AC voltage or DC voltage. 2. DC resistance Refers to the DC resistance of the coil in the relay, which can be passed by a universal meter.

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 ...

The tightly meshing beam field of the safety light curtains PSENopt and PSENopt II is ideally suited for all applications where hand protection is required. By placing the safety light curtain close to the danger zone, the operator can be optimally protected and the workflow will not be interrupted, making it ideal for spaces with ...

With the progress of the industrial level and the improvement of people's safety awareness, more and more attention has been paid to the safe operation of equipment in the workshop. As a professional supplier of safe automation solutions, Pilz's safety products are used in a wide range of industries. Configurable safety control system PNOZmulti ...

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 two-handed button is a commonly used safety start device, which is commonly used in punches, presses, cutting machines and other equipment; The purpose is to force the operator to leave the danger zone with his hands when driving the machine, so as not to come into contact with dangerous moving parts and cause safety accidents. 　　The "standard" of two-handed control says ...

1. Whether the control voltage of the relay module is consistent with the system voltage. 2. It is still possible to use high level and low level for the level control mode of the relay module. 3. Depending on the requirements, choose whether you need a fully isolated relay module. 4. Safety: Relay ...

Pilz safety relays generally consist of an iron core, a coil, an armature, a contact reed, 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. Under the action of electromagnetic attraction, the armature overcomes the pulling force of the return spring and sucks in the iron ...

1. Y0 is connected to one end of the coil A1 of KA1; 2. The other end of KA1, A2, is connected to 24V; 3. Y1 is connected to A1 at one end of the coil of KA2; 4. The other end of KA2 A2 is connected to 24V; 5. COM terminated to 24V. ...

1. After opening, establish a reliable insulation gap to separate the equipment or line that needs to be overhauled from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. 2. According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...
