KFE Special customer requirements Applications Overview Presses Machine Tools Automatization + Feeders Lifting Gear + Mobile Hydraulics Production Technology Special Machinery CAD Download Contact Electric Locking Unit The electric Locking Unit KFE is used as a stepless locking device on round rods and holds axial forces in both load directions without axial play. It is used where hydraulic or pneumatic solutions are not possible. The holding force is created by the proven spring-operated clamping system as it is used in SITEMA’s hydraulically or pneumatically operated Locking Units. At a drop of the control voltage or in case of failure of the electric supply, the Locking Unit KFE clamps automatically. Therefore, it is also suitable for use in safety relevant applications. To operate the Locking Unit KFE, a supply voltage of 24 V and a control signal for the input command “clamp/release” are sufficient. The Locking Unit is self-monitoring and provides output signals...

Displacement sensors models 8710 and 8711 with resistance tracks made of conductive plastic material are designed for a direct and accurate measuring of mechanical displacements. A special ball joint coupling is mountable on both ends of the driving rod. Because of this the sensor may be used free of clearance or lateral forces also with angular or parallel misalignment between sensor and measuring device. A special multi-fingered slider provides a good electrical contact also at high adjustment speeds or vibrations. Areas of application are: —Electromagnets —Switch and button deflections —Pneumatic cylinders —Press-fits (longitudinal press-fits) —Hydraulic cylinders —Measurements of deformation and bending —Length tolerances —Feeding paths Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system.

When we refer nowadays to a potentiometer as a sensor, it is important to bear in mind the statements made here only apply if the potentiometer is connected as voltage divider rather than as a variable resistor (rheostat) (Fig. 2). The wiper voltage must be connected, free of load, to an operational amplifier such as a 741, OP 07 or some other component with a high input impedance. Fig. 3 explains the terms used, such as electrical and mechanical travel. L1 indicates the defined electrical travel. L2 indicates the continuity travel which also includes the non-linear connection fields Fig. 4. L3 indicates the total electrical contact travel of the potentiometer. L4 indicates the mechanical travel. An electrical potential need not be defined for the whole of this travel. In case of nothing otherwise is defined, the fields L1, L2, L3 and L4 are nominally designed symmetrically. Fig. 2 Fig. 3 Fig. 4

Tavrida Electric manufactures small, compact vacuum interrupters with an extraordinarily long mechanical and electrical lifespan. A specially designed axial magnetic field distribution provides an even current density over the contact surface, substantially improving the vacuum interrupting performance. Vacuum interrupter contacts have unique design, based on the mixture of copper and chromium metals and various dopants, to ensure long electrical life of contacts, low contacts resistance and chopping current. The patented, supercompact actuator design allows the circuit breaker to be installed directly underneath each pole. The design is optimal in terms of reliability, dimensions, weight and ease of installation. A spring charged by the magnetic actuator during the closing of the circuit breaker ensures main contacts pressure is maintained. The spring is integrated in the actuator and does not require any maintenance during the circuit breaker's lifetime.

The MX-1000 is ideal for reading 1-D/2-D or DPM codes on automotive parts and label-based barcodes on packages and equipment. The flexible design accepts a variety of both current and future generation mobile devices and augments their capability in a fully ruggedized housing tough enough to stand up to the most challenging environments. The industrial-grade, rugged housing can handle up to 50 drops from 2 meters onto concrete. It is IP-65 sealed and uses inductive wireless charging so there are no exposed electrical contacts to wear out or fail.

The MX-1502 vision-enabled mobile terminal reads codes from as near as 15–30 cm to as far as 10 meters away, making it ideal for scanning barcodes on floor labels, rack labels on high shelves and slips hanging from warehouse ceilings. The MX-1502 is equipped with modular lighting and optics technology (including polarized LEDs and a high-powered lens with liquid lens technology) which provides optimal image formation of any code - even the most challenging direct part mark (DPM) codes. The industrial-grade, rugged housing can handle up to 50 drops from 2 meters onto concrete. It is IP65 sealed and uses inductive wireless charging so there are no exposed electrical contacts to wear out or fail.
