SERVO ACTUATOR
designed for weld gun applications
The compact HT series of high thrust, servo actuators was designed for longer life and no-maintenance performance in scissor, pinch or C-style welding guns. The actuators feature integrated motors, actuators and feedback for decreased weight and footprint. Ideal for easy replacement/retrofitting in fixture or robotic pneumatic guns, the actuators feature large dynamic thrust capabilities and are rated for 6 million welds at up to 2,300 lbs. The factory lubricated and sealed HT series offers advanced design features that not only reduce contamination and maintenance concerns, but also promote a long operating life. Unique bearings on the nose and the nut-thrust tube coupler isolate radial loading that is usually transmitted to the screw/nut and provide anti-rotation.

MICRO PLC
for many applications
The DL06 micro PLC offers fixed models of 36 I/O points or up to 100 I/O points with expansion I/O. It is suitable for a large variety of both discrete and small process applications. The DL06 combines fixed I/O of 20 inputs and 16 outputs with four option card slots for expansion (discrete, analog and communication modules), all in the same package. Nine different discrete modules in 8, 10 and 16-point DC and relay versions are available, as well as four analog modules in mA and voltage versions and a DeviceNet slave module. With the DL06, the same PLC panel layout can be used for all applications from 36 to 100 I/O. It is offered in a variety of I/O combinations and power supply options, including eight models of either AC or DC-supplied units with combinations of AC, DC and relay I/O. The DL06 features 14.8 K total memory and 229 instructions, including 8 PID loops with built-in autotune capability. It also offers two communication ports for programming and operator interface connectivity, as well as RS232/422/485 networking, ASCII In/Out and Modbus

TOUCH-SCREEN PLC
features 255 HMI displays
The Vision 280 touch screen PLC model has a 4.7 inch square touch screen with up to 255 HMI displays. The controller comes with CANbus and MODBUS connection capabilities and an optional Ethernet connection is also available. The standard unit comes with 16 digital inputs, 3 analog inputs; 14 outputs, 2 of which can be used as pulse width modulation to drive stepper motors. The V280 can be expanded up to 158 I/O. As with all Unitronics models, the program is included with the PLC at no charge and the controllers can communicate with DDE servers (Microsoft programs) to simplify data collection operations.

SAFETY LIGHT CURTAIN
offers sensing range to 5 meters
STI introduces the 14mm resolution version of its MicroSafe MC4700 series safety light curtain. The MC4700-14 is available in protected heights from 150mm to 1800mm and offers a sensing range to 5 meters. The safety light curtains are available in standard, segmented or jointed versions. Tight resolution combined with response time as fast as 6.5 msec allows the MC4700-14 to be mounted closer to the pinch points of hazardous equipment. Its compact size permits installation in small areas where other light curtains were previously too large, while providing a built-in appearance. It is ideal for safeguarding small automatic assembly and material handling equipment.
