TRANSPONDER-CODED SAFETY SWITCHES WITHOUT GUARD LOCKING

TRANSPONDER-CODED SAFETY SWITCHES WITHOUT GUARD LOCKING

CES-A Safety Switch

  • Safety switch with integrated evaluation electronics
  • 2 safety outputs (semiconductor outputs)
  • Possible to switch pulsed signals
  • Unicode and multicode switches
  • Connection using M12 plug connector
  • Standard housing according to IEC/EN 60947-5-2, IP67
  • Up to category 4/PL e according to EN ISO 13849-1

Reading and evaluating directly on site

       The compact safety switches in the system family CES-A… combine read head and evaluation unit in one housing. The switches have two safety outputs and one monitoring output. All outputs are semiconductor outputs.

CES-AP Safety Switch

Benefits for you

  • High level of protection against tampering
  • Category 4/PL e according to EN ISO 13849-1
  • Integrated short circuit monitoring
  • Large actuating range
  • Connection via plug connectors
  • Diagnostics using LED

Design and functionality

       The safety switch CES-AP… has two safety outputs. These outputs are connected directly to drives, downstream safety relays or safe control systems. The switch monitors itself for short circuits using pulsed signals. External clock signals are therefore not required.

CES-AR Safety Switch

Benefits for you

  • Possible to connect up to 20 safety switches in series
  • Integrated short circuit monitoring by pulsing
  • Large actuating range
  • High level of protection against tampering
  • Adjustable actuating head with 5 approach directions (only housing C01)
  • Mounting compatible with standard housing according to EN 60947-5-2 (only housing C01)
  • Diagnostics using LED

Design and functionality

       The safety switches are connected together using connectors. The CES-AR-… has two safety outputs. In a switch chain, the signals from the safety outputs are connected to the next switch. The outputs on the last switch in the chain are connected directly to drives, downstream safety relays or safe control systems. The switch monitors itself for short circuits using pulsed signals. External clock signals are not allowed (see next section).

ESL-AR Safety System

Benefits for you

  • Simple and flexible mounting without mechanical effort
  • Lockable to protect against unintentional machine standstill
  • Robust metal housing for harsh environments
  • Maximum safety (Cat. 4 / PLe) thanks to integrated transponder-coded safety engineering

Everything under control – the safety system ESL

       The safety system ESL from EUCHNER is a multifunctional door handle for protecting and monitoring guards such as doors and flaps on machines and installations.

       It consists of a handle and an interlocking module equipped with the proven transponder-coded safety engineering CES. The use of transponder technology ensures maximum safety according to EN ISO 13849-1 (Cat. 4 / PLe) and provides the best possible protection against tampering.

       With the installed CES AR evaluation electronics, up to 20 safety systems ESL or other EUCHNER AR-version products can be connected in series. The ESL is equipped with two easily visible LEDs for status indication, permitting rapid diagnosis.

CTP-I-AP Safety Switch Without Guard Locking

Benefits for you

  • Safety switch without guard locking with interlocking function
  • Integrated CES-AP electronics(A special evaluation unit is not required)
  • Safety category 4 and PL e according to EN ISO 13849-1
  • Mounting compatible with existing safety switches
  • With latching function

AR evaluation unit

Benefits for you

  • Quick overview of the status of each switch in the chain
  • Safety relay already integrated
  • Reduced wiring effort due to AR technology
  • Easy to service due to plug-in connection terminals

Design and functionality

       Using the AR evaluation unit AR switch chains with up to 12 devices can be evaluated. All relevant status information on the switches connected is routed to the evaluation unit using only two inputs. The four safety outputs are switched depending on these input signals. Downstream parts of the safety circuit, e.g. contactors, can be monitored via a feedback loop. The system can be started either manually using a start button or automatically.

       With a total of 14 monitoring outputs, the CES-AR-AES supplies downstream control systems with information on the switching state, as well as any diagnostic messages present.
