RE1/RE2 – Magnetic safety switches
RE1/RE2 magnetic safety switches are equipped with either normally closed (NC) or normally open (NO) contacts respectively and use coded magnetic actuators.
They are easy to clean, making them suitable for contaminated areas or environments with strict hygiene standards.
Their operating principle enables greater tolerances, making them ideal for applications where precise guidance is difficult.
Features
• Response range of up to 7mm (RE1) 9mm (RE2)
• Just one safety switch in conjunction with a suitable safety module makes
it possible to solve applications up to PLe and Cat. 4 (EN ISO 13849)
• Direct connection to the safe control solution eliminates any
additional wiring and reduces installation time
• Space-saving mounting due to compact housing design
• High level of machine availability due to high tolerances for door misalignment
• LEDstatusindicator(RE27)

STR1 – Safety switch
The STR1 transponder safety switch has monitored semi-conductor outputs (OSSDs) and can be safely connected either individually or in series.
It can be used for applications where a high level of manipulation protection is required. The STR1 is available with three codes. Universally coded sensors accept all actuators.
An actuator must be taught into both the uniquely coded and permanently coded variants, this is the only actuator that the STR1 then accepts.
The sensor has three active sensor surfaces.The actuator comes in three different sizes. This allows maximum mounting flexibility.
Features
• Reduced need for storage, as one sensor is suitable for a wide range of different applications
• High level of manipulation protection due to individually coded actuator
• High level of machine availability due to large door offset tolerance and high level of shock and vibration resistance
• Economical solution due to series connection of up to 30 sensors
• Fast diagnosis via LED status indicator Technical specification
• Coding Low or high (EN ISO13849)
• Safe switch off distance Up to 28mm
• Active sensor surfaces 3
• Response time 40mS
• ProtectionIP67
• Ambient temperature -10 to +70oC
