General Purpose Limit SwitchGeneral Purpose Limit Switch
Look at Figures A and B as examples. Actuator type used for test is
the linear Cam travel type as fig. A (b) shown left. The start point is
at the arrow marked "A" (See fig. B). This shows the free position
to be 5.3mm from the vertical center line of the unit. At this stage
there is a circuit between the NO contact terminals 21-22 (indicated
black) but no circuit between NC contact terminals 13-14 (indicated
white). The unit can be actuated until it reaches the operating posi-
tion which is 10.5 mm from the center line. At this point the circuit
arrangement changes no circuit between 21-22 but making a cir-
cuit between 13-14. If, however, the contacts of terminals 21-22
weld together and will not separate, a mechanical safety feature will
take effect if the switch is travelled past the point from which posi-
tive opening is assured, 13.9 mm. Actuator can continue to travel to
the end position (O.T. Overtravel Position) at total travel position
17.3mm. Then it reaches the release position as the lower half of
the bar chart (arrow from right to left). As the switch returns it
reaches the release position at 8.9 mm, there is no circuit between
the contact terminals 21-22. The circuit will change back to the orig-
inal state and the difference(1.6mm) between the operating position
and the release position gives what is known as the differential trav-
el. This is the entire process of switching operation.
SZL-WL-H series general purpose limit switches are specially
designed for world-wide applications and supported by Honeywell
global resources for sales and after sales service.
SZL-WL-H series general purpose limit switches are designed
to the latest IEC standard.
EN50041 limit switches are available in metal enclosures.
Standard SZL-WL-H switch circuit variations include 2 and 3-
circuit versions with forced disconnect mechanism.
SZL-WL-H series includes features to make quick installation
easier and safer. Customers will benefit from Honeywell's vast
experience in serving world industries over many years.
SZL-WL-H switches are interchangeable with almost all other
makes of EN50041 and EN50047 switches.
SZL-WL-H SeriesHoneywell General Purpose Limit Switch
The contact rating Designation relates to the utilization categories
and defines the conventional thermal current lth (A), rated
operational current le at rated operational voltages Ue and the VA
rating. e.g.
A600: "A" denotes the maximum rating(AC), "600" denotes the
maximum rated (AC) voltage.
Q300: "Q" denotes the maximum rating(DC), "300" denotes the
maximum rated (DC) voltage.
IEC standards have been adopted by CENELEC and have been
identified by replacing IEC with EN 60.
e.g. IEC 947-5-1 then becomes EN 60947-5-1. CENELEC has
defined the dimensions and characteristics of two types of limit
switch in the standards EN 50041 and EN 50047.
These standards relate to Low voltage switchgear and controlgear
for industrial use and define the enclosure dimensions, the
operating point for various head actuators, the earth terminal
requirement, the terminal marking and the minimum degree of IP
protection.
IEC 947-1 explains the general rules relating to Low-voltage
switchgear and controlgear. The purpose of this standard is to
harmonize as much as possible the product performance and test
requirements for equipment where the rated voltage does not
exceed 1,000 VAC or 1,500 VDC. IEC 947-5-1 is part 5 of the
general rules which relates to Control circuit devices and switching
elements. Also within this part there is a section which considers
Special Requirements For Control Switches With Positive Opening
Operation. Any control switch which has this positive opening
operation and conforms to these special requirements will be
marked on the outside of the product with this symbol:
The Contact Element Form defines the configuration of the contacts
and the number of contacts within the switch. e.g.
Form Za: both contact elements have the same polarity
Form Zb: the two contact elements are electrically separated
The Utilization Category defines the type of current carried and the
typical application. e.g.
AC15: Control of Electromagnetic Loads, more than 72VA
DC13: Control of electromagnets.
The following example relates to a basic switch which has a snap
action and which has a roller pin plunger actuator.
When reading these bar charts follow these rules:
1. Check what type of actuator was used to test the product, this is
on the drawings which show the head style available. It will be one
of two types:
a. Vertical travel plunger
b. Linear cam travel
2. Start reading from top left of figure B, at the arrow labeled "A".
3. Follow the black arrows and the black strip on the chart. The
black strip indicates that there is a circuit between the terminals
whose numbers are shown on the left and when white there is no
circuit.
All dimensions are in mm.
