Z/T and E.95 range position switches are suitable for sliding and hinged safety guards, which need to be closed to ensure the necessary operational security.
In combination with AES and/or AZR range safety monitoring modules all position switches class 1 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.
Further applications for positions switches class 1 are most varied positioning duties. The variety of requirements to be found in practice can be met in detail by means of a wide range of actuating elements.
Design and mode of operation:
On the position switches class 1 the guarding device and the positive break NC contact are positively linked.

4B Braime has a large range of equipment for use on elevators and conveyors suppliers in both ATEX & non-ATEX areas.
The PST2000A is a double-ended pullwire mechanism with a casing manufactured from polycarbonate and stainless steel sealed to IP65. Its rugged construction makes it suitable for use in the most arduous environments. The PST2000A will cover a distance of 2 x 50M without intermediate switches and conforms to EN620.
This device professional monitors the operation process for potentially hazardous conditions and activate an alarm when it is occurred misalignment, the SRT series suppliers of conveyor belt misalignment switch protects the manufacturers of conveyor belt from damage due to belt misalignment or run offB
For normal condition, the belt misalignment switches are generally mounted on both sides and the edge of the conveyor beltB
A small clearance between the contact industrial rollers and a little swaying for the belt edges are allowable.
When the swaying exceeds the normal limit (on/ about 20 mm), the belt edge pushes the contact roller, which drives the switch and operates the contacts, the misalignment switch will reset automatically when the belt resumes normal running.
These control devices are used in pair on each side of conveyor belt detected place, each unit can be equipped with two micro-switches to produce signals indicating the belt misalignment at two deviation pointsB
The first signal point could indicate small belt deviation by sounding an alarm, the second signal point could guard against extreme belt run off by shutting down the conveyorB
The roller is adjustable up to 20‹ in both directions and is positioned approximately 20mm from the conveyor belt , the switch actuation points are adjustable from 0‹ to 35‹ by a simple change of the actuating camsB

Sun exposure, precipitation and dust deposits can be held through INTERTEC GRP canopy.
For the assembly one or also several devices:
INTERTEC the correct canopy has for each application. INTERTEC there are canopies in the remarks DIA.-HARMS and SD in many different sizes.
One of the areas which makes Idem's Guardian Line Rope Switch Line new and innovative is in the area of rope connectivity. Traditional ‘turnbuckle’ style rope professional fasteners and adjusters are prone to rope slippage and require frequent re-tensioning leading to production loss caused by machine down time.Idem has overcome this common problem by providing a ‘no nuts or bolts specifications’ rope connection system with a ‘Quick Link’ clasp at one end of the rope and a patented Tensioner /Gripping pliers at the other.
The Tensioner / Gripper is located at the switch (rather than elsewhere along the rope length) so that the switch tension window can be viewed.
Final setting and locking can be achieved in a matter of seconds without any need for frequent re-tensioning.
