J.W. Winco (New Berlin, WI) announced it now offers EN 239.4 Plastic Hinges with Integrated Switch, in metric sizes. These RoHS-compliant hinges were designed for monitoring guard doors and covers of machines and production equipment. Opening the door activates the switch contacts, which then interrupts a protective circuit via a break contact (NC) and at the same time signal the door opening by closing a make-contact element (NO). Features include:
• An integrated design, which features an ultrasonically-welded enclosure.
• Matching EN 239.3 hinges without safety switch.
• Four types including: connector plug on top, connector plug on back, cable connection on top, and cable connection on back.
