J.W. Winco Offers Hinges with Integrated Monitoring Switch

NEW BERLIN, WI – J.W. Winco, Inc., a leading supplier of standard industrial machine components, 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).  The integrated design, which features an ultrasonically-welded enclosure, makes these hinges compact, tamper-proof and easy to mount.  J.W. Winco also offers matching EN 239.3 hinges without safety switch.

Hinges are matte black glass fiber reinforced plastic, with hinge pins of stainless steel, European Standard No. 1.4305 (American Standard Series 303).  Versions with switch on the right or switch on the left are available.  Four types are offered: connector plug on top, connector plug on back, cable connection on top, and cable connection on back.  Cable lengths of two or five meters are available.

J.W. Winco offers an extensive selection of inch and metric size adjustable levers, cabinet U-handles, plastic and steel hinges and locking mechanisms, revolving and retractable handles, hand wheels, hand cranks, tube connection and conveyor components, inch and metric construction tubing, shock absorption mounts, leveling mounts, hand knobs, spring, ball and indexing plungers, jig, fixture and fastening components, retaining magnet assemblies, toggle clamps, metric casters and wheels, universal joints, oil sight glasses, and metric tools for the industrial and commercial equipment industries.  J.W.
