For this reason, you must precisely specify the first switching point and the distances from this to any further contacts when ordering the float switches. The nominal length of the float switch is easily determined on the basis of the drawing. PG-/LC version (in cm) Nominal length = 1.5cm (bracket) + switching height + dimension X BK version (in cm) Nominal length = switching height + dimension X | | | | | | Terminal casing LC- | | | | | | | | | | Pi | | B racket SH10--1 Float-swrtch tube — Stop disc —» | | | | | | | | | | | | | | Float | | | | | | | | | | Float switch with 2 contacts, BK version | | | | | | | | | | Stop disc - | | | | | | | | | | | | | | BK version The terminal casing BK (093mm), made of PP, permits connection of the cable and has the degree of protection IP65 (jet waterproof) in accordance with EN 60528. If the switch is exposed to high temperatures (liquid temperature >80°C) or strongly oxidizing chemicals (such as chrome electrolyte or HNOj solutions), the PVDF terminal casing BK/L should be used. The cover can be unscrewed with the universal wrench US for access to cable terminals. LC version The small terminal casing LC, made of PP or LC/L, made of PVDF, permits cable connection and has the degree of protection IP 65 (jet waterproof) in accordance with EN 60528.
