Safety Switches
A safety switch, or disconnect switch, serves as a disconnect means for service entrances and fault protection for heavy machinery. The safety switch disconnects equipment from its power power source and permits safe entry for repairs, maintenance or emergencies.

Safety switches work by monitoring current in a circuit. If the switch detects a fault in the circuit, the switch will instantaneously shut off power to the circuit or device. Safety switches can detect electrical leak, short-circuits, overload, and even equipment failure.

A safety switch can also be triggered by operators or technicians when they open an access panel or guard door for equipment maintenance. When the door is opened, the switch automatically shuts off power to connected equipment and will not reset until the door is closed.

CES Series Image
  • Non-Contact Coded Safety Switches
  • Uniquely Coded Actuators Prevent Defeat
  • IP67 or IP69k Protection
  • Locking Models Feature Guard Locking Forces to 1000 Newtons
  • Battery-Free Actuator
  • 24 VDC Operation
Euchner CES Series safety switches are used to monitor the position of movable machine guarding by means of inductive coding. These systems are designed for use in areas where a high level of tamper resistance and safety is required. These systems feature an inductive read head, evaluation unit/safety module, and a digitally coded actuator. Unlike universally coded magnetic switches, the CES actuators are uniquely coded and cannot be bypassed by any means.
The CEM type read head has an electromagnet built into its housing. This electromagnet holds firmly to an actuator, keeping your door securely locked, and keeping your work area safe.
The CES-AR-C type safety switch is suitable for systems on which a large number of safety doors need to be monitored. The small design of the actuator and read head (including integrated evaluation unit) allows easy placement and mounting for a variety of applications.
NZ-VZ Series Image
  • Electrical, Mechanical, or Manual Guard Locking
  • Holding Force up to 2000 Newtons
  • Adjustable Actuator Head for Multiple Insertion Directions
  • Contacts Monitor both Door Position and Locking State
  • Protection Rating IP65 or IP67
The NZ-VZ Series has an extremely sturdy, die-cast alloy housing with high protection ratings, permitting use under extreme ambient conditions. These switches have positive opening contacts (in accordance to NFPA 79) and redundancy to guarantee that they fail to a safe state.
  • Multiple Connection Options Including Screw Terminals and M12 Receptacles
  • Two or Four Switching Contacts
845 Series Image
  • Approved by TUV and UL
  • Molded cable with crimped ferrules
  • Actuator and read head have high degree of protection IP 67
  • Long mechanical life (100 million operating cycles) of reed contacts
  • Operates perfectly under extreme environmental conditions, e.g. dirt and moisture
According to EN 1088, interlocking devices are mechanical or electrical
devices which are designed to prevent the operation of a machine element
for as long as the movable safety guard is left open.
The EUCHNER safety system CMS is based on the magnetic principle.
The tamper-proof coded system was specifically developed to monitor
moving machine components and movable safety guards.
109 Series Image
  • Terminal Connections
  • Easy to Install
  • UL, CUL Approved
  • IP62 Rated
  • Applications: Econonmical Position Sensing, Terminal Requirement, Non-Wash Down Environments
2204 Series Image
  • Aluminum Enclosure
  • Stainless Steel Armored Cable
  • UL, ULC Approved
  • IP67 Rated
  • Applications: Miniature Low-Profile Design, Stainless Steel Armored Cable for Added Reliability, Wide Working Gap for Overhead Doors, Small Size Less Likely to be Damaged by Forklifts, Aluminum Bar Stock Resists Corrosion in Harsh Environments, Mounting Hardware Included
The 2204 Series overhead door magnetic contact is for use in the rigorous environments of commercial and industrial installations. The floor mount units are constructed with a low profile heavy cast aluminum housing. The reed switch assembly is fully encased in a polyurethane potting material to prevent damage due to moisture or humidity. A wide operating gap distance of up to 3 inches makes installation easy and helps prevent false triggering caused by door movement or damaged and loose fitting doors. The 2204 Series is available with a universal style magnet that allows for greater installation flexibility.
