Peel magnetic relays – a common fault of electromagnetic relays

In addition to the usual emergency stop monitoring, safety gate monitoring, light barrier monitoring and two-hand button monitoring, the safety relays of the PNOZsigma family are also functional, as well as safe speed monitoring, safe braking and braking monitoring. Voltage monitoring safety relays are also one of its features. PNO ...

1. The role of intermediate relays It plays the role of converting and transmitting control signals, that is to say, its input signal is the energizing and power-off signal of the coil, and the output signal is the contact action of the intermediate relay. Essentially, it is a type of voltage relay ...

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 ...

Pilz supports manufacturers and operators of packaging machines in the implementation of packaging automation. As a well-known and trusted provider of machinery safety services to companies worldwide. Use the myPNOZ modular safety relays The first ...

1. Some common faults of high-voltage relay coils 1. The common fault cause of the coil is often disconnected: whether the ultrasonic wave is used to clean the high-voltage relay, or whether the overvoltage is added to the coil will also promote the probability of the coil being disconnected. 2 ...

The Pilz safety proximity switch also belongs to a position sensor with a switching output, its measuring head is usually a plate that constitutes a capacitor, and the other plate is the object itself, when the object moves towards the proximity switch, the dielectric constant of the object and the proximity switch changes, so that ...

Whether on the assembly line or on the machine, the safety rope pull switch is a proven and reliable solution for triggering an emergency stop function from any point on the pull rope to shut down dangerous work processes. Pilz's rope pull switch PSENrope is available in rope lengths up to ...

Recently, the "core shortage problem" has been plaguing major industrial control brand manufacturers, from safety PLCs and inverters, to safety door locks, etc., generally because of the lack of chips, resulting in longer delivery times, and some even unable to deliver the goods at all. This has created a "difficult problem" for the friends in the electrical design department.

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 ...

Automation specialist Pierz is now offering a new service, the Machinery Safety Assessment (MSE), to assess the machinery safety of existing machines. Data reports provide operators with a simple and quick overview of the safety and compliance status of their machines. Pilz provides a comprehensive risk assessment in its portfolio of services.

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...

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 ...

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, ...

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. 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.

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. ...

From June 12 to June 16, 2023, Pilz will be present at the THERMPROCESS trade fair in Düsseldorf, Germany, at booth B10 in Hall 9. Germany Düsseldorf Thermprocess is Germany most important trade fair for industrial furnaces and heat treatment ...

1. High-precision detection: high and low voltage relays can detect high and low voltage signals with high precision, and realize accurate monitoring and control of electrical equipment. 2. Large capacitance switch: High and low voltage relays have good durability and stability when switching high capacitance loads. ...

In machinery safety, if it is an access door that prevents entry into the hazardous movement area, it is usually necessary to use a safety interlock switch to realize the "linkage" between the access door and the movement of the hazardous equipment, and when the access door is opened, the dangerous movement stops. In some cases, it is also necessary to prevent the access door from being hit.

The technology and business of rail freight have remained the same for decades. Until now, in order to test the brakes of freight trains, the crew would walk around the entire train and hit each axle with a special hammer to check the proper operation of the braking system. Rail transport systems in Austria ...
