HLM-Ex Explosion Proof Die Cast Limit Switches Atex

ZONES 1,21,2,22 GAS AND DUST.

IDEM's ATEX Certified range of HLM-Ex Explosion Proof Safety Limit Switches have been manufactured with Heavy Duty Die-Cast Metal bodies and have been designed to be mounted for position sensing of moving applications e.g. guard doors, conveyors, machine beds, elevators in atmospheres where the potential for explosion exists.

They are available with a choice of linear or rotary heads.

Operation of the switches is achieved by a sliding actuation of the moving object to cause deflection of the switch plungers or levers.

For safety applications it is important that the moving object does not pass completely over the switch actuators so as to either cause damage to the actuator or allow it to return to its original position.

All HLM Explosion Proof Limit Switches are supplied pre-wired with 3m of cable.

FEATURING:

Heavy duty die cast body.

Industry standard mounting to EN50041.

Choice of actuator heads: Linear and Rotary.

High mechanical life 5,000,000 cycles.

Rated IP67 making them suitable for washdown.

Emergency Stop (E Stop) switches are used by operators to shutdown a machine, system, or process.

Emergency Stop Switches are mounted on machines and sections of plant conveyors that cannot be protected by guards.

In combination with any dual channel safety monitoring controllers these switches can be used as emergency stop devices and monitored for up to Category 4/PLe to ISO13849-1.

All IDEM's Emergency Stop Switches conform to European Standard EN ISO13850 (formerly EN418) and IEC60947-5-5. They have a positive mechanical linkage between the switch contacts and the E Stop Button. The switches are mechanically latched and can then only be returned to the operational condition by pressing the reset button as required by EN ISO13850.

IDEM's range of Explosion Proof E stop switches can withstand sparking and flames and are IECEx and ATEX certified.

ZONES 1, 21, 2, 22 GAS AND DUST.

STAINLESS STEEL 316. M30 x 1.5mm THREADED BODY.

IDEM's RM-Ex Explosion Proof Non Contact Switch is manufactured with a Stainless Steel 316 Cylindrical housing making it suitable for industry applications where the threat of explosion exists, particularly in the hazardous conditions created within the Petro-Chemical, Food Processing and Pharmaceutical industries.

The RM-Ex is designed with highly reliable power reed switching elements, contacts de-rated and protected by internal fuses with high tolerance to guard misalignment.

Manufactured with a magnetic sensing system which provides a wide sensing distance and provides a high tolerance to misalignment after sensing. The RM-Ex can be fitted behind stainless steel fittings and can operate in extreme environments of temperature and moisture.

The switch comes pre-wired with either 5M or 10M of cable and is available with 2NC 1NO circuits.

The RM-Ex is particularly advantageous when:

(a) poor guard alignment exists.

(b) high hygiene requirements exist, e.g. food industry hose down.

(c) a long mechanical life is required (no moving or touching parts).

Installation of all IDEM Non Contact EX Switches must be in accordance with a risk assessment for the individual application.

Pintsch Tiefenbach
Solenoid Switches for Steel Plant, Mines, and Ports
Heavy Duty
High temperature.
General Information
• Contact-free actuation thanks to
permanent magnets
• Maintenance-free
• High rupturing capacity
• Wide temperature range
• Suitable for any installation position
• High responsiveness
up to max. 30 m/s
• Long service life of 109 switching cycles
• Virtually no inertia
• With cable set or cable compartment
• Cable lengths of 2 m, 5 m, 10 m, 15 m etc
Cable:
standard Ölflex (oil-resistant),
silicon (temperature-resistant up to 180 °C),
Purwil (UV-resistant)

Application
The switches are used as magnet-sensitive, non-contact pulse and
latching switches.
Components and mode of functioning
The solenoid switches consist of cast-resin insulated inert gas contacts
that are integrated in a corrosion-proof switch housing. By moving
a magnet passed the switch the contact closes or opens. During the
closing procedure the magnetic field increases in a square progression
while the gap between the contact studs becomes increasingly
smaller and then the contacts close with snap action. Due to the small
distance between the contact studs and their low mass the contacts are
switched with virtually no inertia.
Pulse switch (monostable)
In this switch design the switch is actuated for as long as it is influenced
by the magnetic field. When removing the magnet the switch returns to
its resting position.

Advanced Inductive Proximity Switches for Steel Plants, Chemical, Fertilizer, Process, Mines, and Related applications.

For operations in Ambient Temperature 100*C or 125*C, for example extremely close to Ladle  or Hot Metail Applications in Steel PLants or In Chemical Cracker Plants in Oil and Petro Processing.
.
A ,,shielded" or ,,flush' proximity switch will not be affected by surrounding metal.
An ,,unshielded' or ,not flush" proximity switch must have an open space around the active face.
d >d d Steel shielded shielded If proximity switches are installed opposing one another, the op posing switches must be installed with a spacing of 3 x the switch diameter between them.

a > d ( interspace > diameter> ) If unshielded proximity switches are to be installed side by side the following spacing must be observed: a > 2 d (interspace > 2 x diameter) Cable Installation
To avoid pick up of induced voltage and current peaks, connecting wires for proximity switches should be installed separately from motor-magnet or valve-wires Cable length
Extremely long cables will add a capacitive bad to the output and increase interference. Cables for AC-and DC-switches should not exceed 100 m (300 ft) substantially. Cables for NAMUR-switches should not exceed 250 m. (750 ft)
Magnetic fields Strong magnetic fields may increase the sensing range or even trigger off a proximity switch. Radio frequencies may also influence a
proximity switch. At installations with strong sources of radio interference the proximity switch and cable should be shielded. Actuating area The actuating area is a limited zone in front of the active face of a proximity switch. Within this area a target will be detected and turned into a switching signal'. Sensing range a.) Nominal sensing range Sn The nominal sensing range Is the value obtained when (he ambient temperature is held at 20 ~C and voltage between 12-24 V. Under
these conditions the switching point must be within a tolerance of 10 %.
b) Real sensing range Sr This is the actual switching distance for an individual proximity switch lt is measured at nominal voltage and ambient temperature of 20 ºC and will be between 90 % and 110% of Sn.
