EN 239.4 hinges with integrated switch 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.
Maximum heat resistance of plastic: 80°C (175°F).
Operating instructions showing additional important technical information are included with every hinge.
For matching hinges without safety switch, see EN 239.3.
