EFM SERIES MINIATURE METAL SAFETY LIMIT SWITCH Description The EFM series have been tested and approved to meet the requirements of the Low Voltage directive and positive opening safety contacts per IEC/EN 60947-5-1-3. Typical applications for these switches would use the roller plunger in conjunction with cams on doors with hinges . A rang of panel mounting or top mounting versions are also available to ensure that the switch can be simply installed in small space or difficult mounting. Features Conforms to EN (TUV) standards corresponding to the CE marking Positive opening operation of NC (Normally Closed) contacts conforming to IEC /EN 60947-5-1 Wide standard operating temperature range: -25C to 70C Full range of actuator heads and levers suitable for safety applications Sealing up to IP 67 International conduit sizes Specifications Safety Ratings EN 945-1,ISO 13849-1,IEC/EN 60204-1,NFPA 79,EN 1088,ISO 14119, Standards IEC/EN 60947-5-1,ANSI B11.19 AS 4024.1 Safety Classification Cat. 1 Device per EN 945-1 Dual channel limit switch suitable for Cat 3 or 4 systems Certifications TUV and CE ,marked for all applicable directives Outputs Operating Characteristics Safety Contacts 1 N.C. snap acting Actuation Speed.
