Pierz switches – what are the properties of safety switches?

1. The relationship between the specifications of the relay and the installation location For different star/triangle control positions, the specifications of the selected thermal relays are also different. As shown in Figure 1, the current setting value of the selected thermal relay is equal to the rated current value of the protected motor. In Fig. 2, the selected thermal relay ...

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. ...

1. The overload capacity of the transistor is less than the overload capacity of the relay In general, in the case of a large inrush current (e.g., bulbs, inductive loads, etc.), the transistor overload capability is smaller, and more derating is required. 2. Under the condition of rated operation, the relay has the number of actions ...

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.

1. 3-pin relay wiring The common 3-pin relay is the car horn relay. No. 1 is the contact terminal, which connects the load; No. 2 is the common terminal between the contact and the coil, which is connected to the power supply; No. 3 is the coil terminal, which connects the button switch (such as the horn on the steering wheel).

Since its launch, Pilz's flagship product, the configurable and safe small controller PNOZmulti, has been impressed by users for its robustness, flexibility and ease of operation. PNOZmulti Configurator as a configuration tool for the safe small controller PNOZmulti ...

In the context of industrial automation, the term "safety" refers to the functional safety of equipment, which means that people and the environment are protected from damage from foreseeable coercion from machines, and the residual risk is more or less always present, but the residual risk cannot exceed the acceptable level. Through the use of security relay ...

In the safe configurable small controller series PNOZmulti 2 from Pilz, a new stand-alone base module PNOZ m C0 is now available. PNOZ m C0 has the structural characteristics of a safety relay, but it is just as powerful as a safety controller. It offers 8 ...

From 8 to 10 November 2022, at the SPS trade fair for intelligent production solutions in Nuremberg, Pilz will focus on automation solutions for safety and industrial security in plants and machinery under the theme "Safe and reliable". 　　Safe and cost-effective control ...

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. ...

There are 3 basic forms of relay contacts: (1) The two contacts are disconnected when the dynamic type (normally open, H-type) coil is not energized, and the two contacts are closed after the energizing is applied. It is represented by the pinyin prefix "H" of the word "合". (2) Dynamic breaking type (normally closed, D-type) coil is not energized when the two contacts ...

Industrial security has become an integral part of automation, but with new requirements and specifications, manufacturers, integrators, and operators are faced with the question of how their employees can meet the new challenges. In response, Pilz has launched a new safety training course that can help students learn ...

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 ...

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 ...

1. The fastener itself needs to be reliable and stable enough. 2. Need to rely on special tools to remove, such as hexagon screws, star screws, etc. Phillips/slotted screws are not recommended, as in some cases they can be easily fitted with fingernails or on the go.

How do you grasp the issues of employee protection, responsibility protection, work efficiency, and data protection? How can you improve quality and at the same time prevent machines from being tampered with? How can data and employees be protected in equal measure? Through I.A.M. (Identification and Access Management) "...

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...

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 ...

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 ...

1. The installation of the safety grating must be able to effectively prevent bypassing the detection area of the safety grating and contacting the dangerous moving parts, that is to say, the detection area of the installation grating can not have a blind spot, if the top or bottom of the safety grating has a fixed guard, the guard should be able to ...
