SIGUARD Interlock Switches with Locking Tumbler - 3SE5

SIGUARD interlock switches with tumblers are exceptional, technically safe devices which restrict and prevent an unforseen or intentional opening of protective doors, protective grilles or other covers as long as a dangerous situation is present (ie: extended run down time of motion during the shutdown of a machine)

Plastic & Metal Housings
Interlocking with either spring or magnetic force
Electromagnetic tumbler
High Locking Forces up to 2600N (Metal) and 1300N (Plastic)
Wide range of "Release Mechanisms" available to handle any application
5 Actuator approach directions
4 switch contacts
Standard/Radius actuation

Positive Opening according to IEC947-5-1

SIGUARD Hinge Switches

The 3SE2283 hinge switches are particularly suitable for use in doors and flaps of machines that must be closed to ensure the safety of operating personnel. It's thin profile and compact design allow it to be directly mounted on a hinged protective protective cover and the stable frame

Intergated Switch Block (1NO+2NC or 3NC)
Additional Hinge is included
Positive Opening according to IEC947-5-1

SIGUARD Magnetically Operated Switches

SIRIUS Magnetically-operated switches are ideally suited to monitor protective doors. They operate contactlessly. The reed contacts in the switching element are actuated via a coded switching magnet and are therefore especially tamper-proof.

System comprising magnet, switching element and evaluation unit
Monitoring of 1 to 8 protective doors with a single evaluation unit
Manipulation-proof due to coded switching elements

SIGUARD Cable Operated Switches

Safety right down the line - reliable protective, even over distances up to 100 m. SIRIUS Cable-operated switches are used for monitoring or as "E-Stop" equipment on plant sections that are particularly at risk

Plastic & Metal Housings
"E-Stop" function with latching according to EN 418
Models for cable lengths up to 100 m
Comprehensive range of accessories for cable mounting
Positive Opening according to IEC947-5-1

SIGUARD Foot Operated Switches

Available in metal or plastic housing for rugged applications
One or two-pedal operation
Available with or without covers
Contact systems 1NO/1NC, 2NO/2NC and 1 changeover
Switching and latching contacts
Safety foot switches with latching according to
EN 418

PSEN Safety switches for every environment As they are dust-tight and waterproof, secure against manipulation due to evasion protection and have a long service life, Pilz safety switches are ideally suitable for monitoring safety gates and have a wide range of uses: in classic mechanical engineering as well as sectors with rigorous hygiene requirements, such as the food, packaging or pharmaceutical industry As a Solution Supplier, Pilz offers you the optimum solution for secure safety gate monitoring: non-contact, magnetic safety switches on the input side, in conjunction with proven evaluation devices - including safe relay, semiconductor and power outputs - on the output side.
Mechanical safety switches PSENmech For applications in which the safety gate is not to be opened unintentionally. Prevent premature operator access via increased extraction force. PSENmech mechanical safety switches with guard locking ensure that the safety gate is interlocked until the hazardous production process is complete.
Non-contact, coded safety switches PSENcode Based on a non-magnetic action principle, these are particularly suitable for use on metal processing plant and machinery Highest level of manipulation protection because the enable from the safety device is only triggered if the actuating element is within the switch's response range and the code number on the actuator matches that of the switch (key lock principle).

Safety Gate Switches

Eaton’s Cutler-Hammer has the products designed and tested to protect machine operators.
The E48 Safety Key Interlock Limit Switch is designed to be used with movable guards or covers which must be closed for operational safety. The key portion of the switch is affixed to the movable door, cover or other such guard. The switch itself is mounted to a rigid portion of the machine. When the guard is opened, the key is removed from the switch, thereby positively breaking the normally closed contacts. This interrupts the control circuit, stopping machine operation.
