The NDLWS/501D from K.A. Schmersal GmbH & Co. KG is a high-quality illuminated pushbutton for front panel mounting. Featuring a round design, the pushbutton has a white button surface and a silver bezel ring made of chrome-plated ABS plastic. With its hygiene certification and IP69K protection rating, the pushbutton is particularly suitable for applications in hygiene-sensitive areas such as the food and pharmaceutical industries.

The pushbutton is equipped with lip seals and can be installed in any mounting position. The actuator is made of durable plastic and offers full insulation with a mechanical lifespan of at least 1,000,000 switching cycles. The pushbutton has an actuation travel of 5 mm and requires an actuation force of approximately 1.5 N, ensuring reliable and comfortable operation.

The NDLWS/501D supports up to two contact elements and is mounted using a central nut. The installation diameter is 22.3 mm, and the mounting height above the front panel is 11 mm. The pushbutton comes with a mounting flange and can be securely fastened with a tightening torque of 0.6 Nm.

The pushbutton is illuminatable and suitable for various control and operating elements. It is highly resistant to shock and vibration, with a shock resistance of 30 g / 18 ms and a vibration resistance of 20 g / 10 to 150 Hz, making it reliable even in demanding environments.
