AutomationDirect Expands Safety Switch Line
April 18, 2013—AutomationDirect has expanded its line of safety products with additional tongue interlock and cable-pull safety switches. Tongue operated safety interlock switches are designed to fit to the leading edge of sliding, hinged or lift-off machine guards and provide positively operated switching contacts. They provide a tamper resistant actuator mechanism and robust position interlock detection for moving guards.
Available in 22 mm, 30 mm and 40 mm mounting profiles, models are available in plastic, aluminum and stainless steel housing options. The switches are designed with multiple actuator entry points and offer adjustable heads with 90-degree and 180-degree options; switch styles provide single and multiple half-inch female NPT conduit openings. Interlock safety switch prices start at $15. Interlock switches require actuator keys which are sold separately in several styles, starting at $1.25.
Additional cable-pull safety switches are also available. Cable-pull, or grab-wire, safety rope switches are designed to be mounted on machines and sections of conveyors which cannot be protected by guards.
Newly added models include a 57 mm wide die-cast aluminum body which supports up to a 50-meter cable; 65 mm models are available in aluminum or stainless steel and support cable lengths up to 100 m. Models provide ½ inch NPT openings, and are available with or without reset button; units with an e-stop button, as well as red/green LED (24VDC or 110VAC) versions are also available. Cable-pull safety switches start at $20.50.
Rope kits, starting at $58, are available with galvanized or stainless steel cable and contain eyebolts, tensioner, and cable (up to 80 m) with pre-mounted eyelet and quick link.
Additional accessories available include steel rope in lengths from 5-126 meters, stainless or galvanized eyebolts, springs, tensioners and pulley assemblies, as well as replacement LEDs.
