摘要： An industrial locking switch comprises multiple locking tongue entry slots formed on adjacent sides of the locking switch housing, thereby supporting receipt of the corresponding locking tongue from multiple directions of approach without the need to mechanically modify the switch's head or to reorient the switch itself. The locking switch houses locking bolt detection circuity comprising multiple series connected RFID coils configured to detect an RFID tag mounted on the locking tongue when the locking tongue is inserted into any of the entry slots.

摘要： A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).

摘要： An image forming system comprises a first housing, a second housing and a third housing. The second housing may comprise a motor, a first door and a first switch. The first switch is provided on an electrical path connecting a power supply and the motor, for switching between a first state and a second state and for switching from the first state to the second state. The third housing may comprise a load. When the first door is opened in a state where the first switch is in the first state, the first switch switches from the first state to the second state to cause supply of electric power to the load to be cut off.

摘要： A sensing and alert system is installed in a plurality of electrical switchgear cabinets. Each switchgear cabinet includes at least one high-voltage circuit breaker, and each switchgear cabinet is in communication with a central programmable logic controller (PLC) configured to activate and deactivate the high-voltage circuit breaker in the corresponding switchgear cabinet. The sensing and alert system includes a time of flight (ToF) sensor arranged to capture real-time image data, a lighting module affixed to an inside portion of the switchgear cabinet, and a processor operatively coupled to the ToF sensor and to the lighting module. The sensing and alert system is affixed to an inside portion of each switchgear cabinet. The processor compares real-time image data from the ToF sensor to the stored calibration image data and transmits an alarm if the difference is greater than a predetermined amount.

摘要： An actuator (3) for a safety switch (2) with an actuator head (8), said actuator head being mounted to a core body (6) by means of a connection element (7). The actuator head (8) has, at least in parts, a larger cross section than the connection element (7). The connection element (7) is rigid in the axial direction. The actuator head (8) is held in a base position by means of the connecting element (7). In this base position, the longitudinal axis of the connection element (7) runs at an angle of inclination to the surface of the core body (6).

摘要： Disclosed is a method for controlling an installation for handling hollow bodies, which includes: a plurality of treatment units; a transfer system; and a covering including a frame that defines casings and door leaves each mounted on a casing; a control unit. Also included are steps of: detection by the control unit of the stopping of a treatment unit; detection by the control unit of the closed position of door leaves located in the vicinity of an interface between the detected treatment unit that is stopped and the transfer system; and if these door leaves are detected in closed position, ordering by the control unit of the locking of these door leaves.
