GENERAL INFORMATION
ZLS series limit switches are specifically designed for world-
wide applications and is supported by Honeywell global
resources for sales and after sales service.
ZLS series limit switches are designed to the latest IEC
standard are available and include a wide range of EN50041
and EN50047 type switches. Miniature EN50047 limit
switches are available in metal and double insulated
enclosures and a metal enclosed 3-cable entry version
(EN50047 mounting compatible) is also offered.
Standard ZLS switch circuit variations include 2 and 3-circuit
versions with forced disconnect mechanism. ZLS includes
features to make quick installation easier and safer.
Customers will benefit from Honeywell’s vast experience in
serving world industries over many years.
Most ZLS versions are interchangeable with almost all other
makes of EN50041/47 switches.
TYPICAL APPLICATIONS
Machine tools: metal fabrication equipment, presses,
transfer lines and special machinery
Material handling equipment: conveyors, elevators, cranes
and hoists
Packaging machinery and process equipment

STANDARDS
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
Controlcircuit 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 (AC)
Alternating current, (DC) Direct current and the typical application
in which the switch is used e.g.
AC15 – Control of Electromagnetic Loads (less than 72VA)
DC13 – Control of electromagnets.
The contact rating Designation relates to the utilization
categories and defines the conventional thermal current lth (A),
rated operational current le (A) at rated operational voltages Ue
and the VA rating e.g.
A600 – The ‘‘A’ denotes the maximum VA rating (AC) and the ‘‘600’
denotes the maximum rated (AC) voltage.
Q300 – The ‘‘Q’’ denotes the maximum VA rating (DC) and the ‘‘300’’
denotes the maximum rated (DC) voltage.
These IEC standards have been adopted by CENELEC (The
European Commitee for Electrotechnical Standardization) 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.
