S10 - Safety Interlock without Guard Locking

Safety interlocking devices, series S10, are used to monitor the position and electrical locking of protective devices (e.g. safety doors) in industrial machinery and systems. In this way, they protect people from dangerous machine movements.

Safety interlocks without guard locking can be implemented whenever the dangerous movement has come to a standstill before the person entering can reach the danger point.

Advantages
•  BG and UL approval (EN 1088, IEC 947, DIN VDE 0660)
•  Compact design, 40 mm mounting possible
•  Plastic enclosed design
•  4 approach directions possible
•  Variable actuating radius possible with radial actuator
•  Actuating heads can be displaced 4 x 90°
•  Ball lock in the actuating head for fixing the actuator
•  Auto-centering due to funnel-shaped insertion opening
•  Contact units suitable for integration from Category 1 to 4


S40 - Safety Interlock without Guard Locking

Safety hinge switches, Series S40, are used to protect people in the operating range of industrial machinery and systems. They are designed to monitor the position of pivoting protective devices (e.g. safety doors) by means of a monitoring switch integrated into the hinge.

Advantages
•  BG and UL approval (EN 1088, IEC 947, DIN VDE 0660)
•  Considerably easier to mount onto pivoting protective devices
•  Simplified construction compared to interlocking devices with elaborate cam discs
•  The safety contact in the switch opens as soon as the protective device has reached an opening angle of approx. 3.5° and above
•  Protective device can have a maximum opening angle of 135°
•  Contact units suitable for integration from Category 1 to 4
•  Can be mounted on 40 mm, widely available aluminum profile systems
•  Optional mounting hinge sets available for 30, 35 and 45 mm profile systems

L30 - Safety Interlock with Guard Locking

Due to their slim and narrow design, the L30 Series is particularly well-suited for use with revolving doors mounted on commercial aluminum profiles. The interlocking devices L30 are available in a spring-operated version for personnel protection and in a magnet power-operated version for machine protection. A mechanism for preventing unwanted closing and an auxiliary release mechanism are additional advantages of these safety components.

Advantages
• BG and UL approval (EN 1088, IEC 947, DIN VDE 0660)
• Slim L-shaped design for optimum integration into rotating protective devices based on profile systems
• universally usable due to 4 approach directions
• Actuating head can be displaced 4 x 90°
• Funnel-shaped entry with a auto-centering effect
• Transverse sliding adapter plate for fast, easy mounting on revolving doors with a profile system assembly
• Dust-proof flap prevents dirt particles from entering when the protective device is open
• safety mechanism for preventing unwanted closing, contact unit up to Category 4
• Manual auxiliary release of the guard locking is possible no matter what state the guard locking mechanism (i.e. the solenoid) is in
• spring power-operated version L30-F/.. for personnel protection
• magnet power-operated version L30-M/.. for machine protection


L50 - Safety Interlock with Guard Locking

The Series L50 interlocking devices with an enclosure rating that surpasses IP 67 are oil- and gasoline-resistant and can withstand even hostile ambient conditions. They are available in a spring-operated version for personnel protection and in a magnet power-operated version for machine protection.

Advantages
• BG and UL approval (EN 1088, IEC 947, DIN VDE 0660)
• Heavy-duty construction, suited for use under hostile ambient conditions
• Universally usable due to 3 approach directions
• Funnel shaped entry for the actuator
• Ball lock in the actuating head for fixing the actuator
• Actuating heads can be displaced 3 x 90°
• Variable actuating radius possible with radial and telescope actuator
• Safety mechanism for preventing unwanted closing, contact unit up to Category 4
• Manual auxiliary release of the guard locking is possible no matter
• Spring power-operated version L50-F/.. for personnel protection
• Magnet power-operated version L50-M/.. for machine protection


BL, BS - Safety Door Bolts for Safety Interlocking Devices S10 and L50

The Series BL and BS safety door bolts with integrated telescope actuators serve as a prefabricated mounting support and eliminate the need for the user to undertake mechanical adaptive measures. At the same time, the safety door bolts act as an end stop and protect the interlocking devices from sustaining damage.

Advantages
• Allows quick and proper mounting of safety interlocking devices
• Simple mounting on aluminum profiles, square pipes and machine cover panels
• Universally suitable for right-stopped or left-stopped safety doors
• Mechanical end stop function protects the interlocking devices
• Prevents the machinery from starting up inadvertently due to accidental closing
• Suitable for safety interlocking devices Series S10 and L50
