Product Description

                                                                 Position Switch

Definition:
The position switch is mainly composed of switching elements, wiring terminals, switch operating parts, and transmission parts. According to the mechanical mechanism of switching on and off the switch contacts, the switching elements have the following two types:
slow action switch: the switching on and off of the switch The switching time of the opening action is related to the operating speed of the switch, the faster the operating speed, the faster the switching of the switch.
Quick action switch: the switching time of switching on and off of the switch is related to the speed switch and the operated speed switch. As long as the operating part of the switch is operated to a certain position, the switch will switch on and off. The process time is generally is the time required for the spring to bounce, this time is very short and is a constant.


Principle:
When the DC current is disconnected, the current flashover is required to disappear quickly.
The quality and technical indicators of limit switches, in addition to meeting the international electrical standard indicators, also have important technical parameters such as switch mechanical life, protection level, electrical performance, switching time accuracy and repeatability accuracy. Quality plays a vital role. Schmersal's switches are famous for their long service life, high repeatability and stable electrical contact performance. Every component of the switch is carefully treated from material selection to production, and the quality is strictly controlled.

The shell of the switch has two kinds of metal and plastic. The metal shell is made of die-cast zinc or die-cast aluminum, all of which have been treated with anti-rust surface, which has the characteristics of anti-corrosion of sea water, oil stains and chemical gases. The plastic shell material is glass fiber reinforced thermoplastic, which is durable and has the characteristics of positive combustion, in line with UL standards .

Design and Function:

All limit switches are equipped with positive open normally closed contacts in accordance with IEC60947-5-1 standard, and have snap action and slow action. In combination with a safety controller, a single limit switch achieves safety category PLd. The use of two limit switches achieves safety category PLd in accordance with the requirements of ISO138 49-1.

Modular Diversity:

The modular design combined with the various actuators enables a wide range of applications in all individual disciplines of machine and plant engineering.

Advantage:
1. reliable position detection.
2. Metal or thermoplastic housing.
3. High versatility, safe and reliable.
4. Modular design, can be combined in many ways.
5. Suitable for ambient temperatures down to -40 °C.
6. The angle of the joystick can be adjusted 45° at a time.

Standardized Structure:

Folding lock cover
All plastic versions come with a folding and locking locking cover. The cover can be opened with a screwdriver and closed without tools.
Reduce Assembly Time
The connection terminals on all actuators can be rotated by 45°, which greatly reduces the assembly time.
Actuator Head Replacement and Rotation:

PS116
Due to the simple mounting design, the adjustment is rotated by 45°, which means that at any time, the actuating head can be adjusted in the prescribed actuating direction.
PS2xx / PS3xx
The symmetrical layout of the housing means it can be used in both left-handed and right-handed versions of the same switch, which applies to both the cable and connector design.
Application:
Type 1 PS limit switches according to ISO 14119 are suitable for confirming and monitoring the position of moving parts and laterally movable or rotatable protective equipment, and can be used in all industrial environments.
The PS series limit switches with protection grades up to IP66 and IP67 meet the needs of use in harsh environments.
The position switches with safety function are suitable for sliding and hinged guards, which need to be closed in order to ensure the required operational safety.
In combination with safety control modules all safety switches with class 1 shown in this chapter achieve Control Category 3 or 4 to ISO 13849-1.
Further applications for positions switches class 1 are most varied positioning duties. A comprehensive range of actuating elements is available to meet the requirements of many everyday tasks.

Design and mode of operation:
On the position switches class 1 the guarding device and the positive break NC contact are positively linked.
Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
