Description

The JOLA ball-shaped FS float switch is designed for vertical or horizontal mounting to signal the level of liquids. The level switch has a gold-plated internal switching contact, which ensures long and reliable switch life and operation. To ensure correct switching, the cable must be fixed at the required height by means of a process introducer, for example in the case of fixing from the side, or by means of a weight, for example in the case of fixing from above.

These units are not suitable for use in turbulent liquids (e.g. in mixing tanks). The float is rated IP68. The maximum immersion depth of the float is 10 m of water at +20 °C. The switch can be ordered in ten versions: 1 / K / … or / S1 / K / … with gold-plated contact and 3 / K / … or / S3 / K / … with AgNi contact for AC/DC voltage of 24 V. The 1 / K / … or / S1 / K / … is used for smaller currents and operates reliably after years of operation. 3/K/… or /S3/K/… is the most commonly used, as it allows higher voltages (up to 250 V) for standard applications.
