ROUND UP

SMC , provider of pneumatics, redesigns its air preparation modular units, the AC series, thus ensuring its number one spot in the marketplace. The AC series design review is part of SMC’s ongoing investment in research and development to refine and improve the per- formance and functionality of its products, as well as developing new innovations to drive enhanced handling and space sav- ings and deliver competitive advantages for customers. In this regard, the AC series brings a double layer structure bowl guard for better visibility and extended working life, while also bringing reduced time and space for maintenance. Much more space saving is achieved due to the compactness of the modular units and the integrated and selectable pressure gauges and switches. Moreover, the introduction of an in-bowl assembled element construction, together with a new bracket system that allows for initial tightening by hand, allows for easier control and quick in-hand maintenance and replacement of elements. Ideal for automo- tive, facility and machine manufacturing, these highly flexible FRL units also feature a simple to use bowl lock button and inter- changeable, modular mounting. Quick facts: Better visibility and environmental resistance Easy replacement of the element The element and the bowl are in one piece Replacement can be done in hand Reduced required maintenance space: Max 46% reduction Regulator: Set pressure 0,05 to 0,85 MPa, 0,02 to 0,2 MPa Selection of pressure gauges Square embedded type pressure gauge, Round type pressure gauge, Digital pressure switch Enquiries: Email sales@smcpneumatics.co.za Air preparation modular units - redesign

Belt drift switch for field applications The new belt drift switch from ifm electronic is designed for heavy duty application and used for drift monitoring of conveyor belt installations.The belt drift switches are used to protect the installations from damage or destruction in the event of belt drift and are positioned in pairs on both sides of the conveyor belt.The ball bearing stainless steel actuating roller is resistant to wear and is used for belt speeds up to approximately

5 m/s.The device features a robust aluminium housing and is equipped with two force-actuated changeover contacts with a snap-action function with two adjustable switching points. Inadmissible belt drift occurs when the belt edge approaches the end of the supporting rollers through lateral movement and surpasses it.Then the actuator (roller lever) is operated and displaced. In case of displacement of the actuator, the cam operating switches are activated. The switching angle can be set via an adjustable camshaft. In this way, a pre-warning can be implemented in addition to the safety shutdown. As soon as the belt moves correctly, the roller lever will automatically return to its home position.
