LVD
EN 61010-1:2001 The KD-2446 unit requires the use of a limited energy power supply circuit per EN 61010-1:2001 Article 9.3. The KD-2446 does not use or switch voltages in excess of 60 VDC or 42.4 VAC peak (30 VAC rms).

Sensor Cables

In-line cable connector splice
Many sensors come with integral sensor cables. Routing this cable in some applications is difficult and something you only want to do once. Including an in-line connector splice in the cable, near the sensor itself, allows for easy sensor replacement should the need arise.

Hermetic in-line connector splice
Some applications pass the sensor through a pressure boundary, most commonly a vacuum chamber wall. We offer an in-line hermetic bulkhead splice for these applications.
