JW Winco has released new intelligent standard parts with signal feedback, ensuring greater safety, higher efficiency, and increased stability.
The new smart GN 251.2 stop bolts are supplied with a hardened spherical head that serves as an end stop. The two hex nuts allow exact positioning with counter-locking. This means that when a workpiece contacts the bolt head, the built-in limit switch transmits an electrical control signal. By means of the knurled screw, the limit switch can be installed and removed without the need for loosening the stop bolt.
JW Winco has also released the GN 817.6 indexing plunger, along with its pneumatically-operated, fully compatible counterpart, the GN 817.7 to align and temporarily lock two parts together. The plungers include a sensor to ensure correct positioning, providing electronic monitoring of the plunger pin state.
Information on the safety-related opening operations is provided by the safety hinges of the GN 139 and EN 239 series, which are available in zinc die-cast, stainless steel, and fiber-glass-reinforced polyamide. The angle-dependent switching point can be adjusted individually, and a combined closing and locking query can be made in conjunction with the above-mentioned indexing plungers. This improves safety and saves energy. For example, if machine doors need to be closed to ensure effective cooling in control cabinets.
There are other control elements in JW Winco’s portfolio, including the GN 331 and GN 332 machine tubular handles provide status information via a light signal, the push button can call up further functions, and the emergency stop switch interrupts the system’s safety chain and safely stops it to protect the operator from injury or damage.
The GN 422 and EN 628.4 cabinet U-handles use a push button, but do not have an emergency stop. The GN 3310 switches provide immediate feedback in the form of a red or green illuminated push button.
