LX918 series marine limit switchesDetailed product description：

Purpose
The LX918 series limit switch is used in circuits with AC frequency of 50-60Hz, voltage up to 500V, and DC voltage up to 440V to limit the travel of various mechanisms. It can also be directly used as a limit switch for 5.5kw three-phase squirrel cage asynchronous motors (main source of two-phase ignition).
Structure and working principle
The casing of the limit switch is made of copper alloy, which has good mechanical strength and corrosion resistance. Under the environmental conditions of marine vessels, the performance of materials will not deteriorate. The shell type is protective, with a protection level of up to IP67. Due to the action of the spring, it can automatically reset. Operation position: 45 ° → 0 ° ← 45 ° The contact opening and closing of the limit switch are determined by the cam position. Compliant with standards
Meets the special requirements of IEC377-2 control switch and has passed the inspection of China Classification Society, complying with marine standards. The nameplate is marked with the CCS ship inspection mark.

The rated working voltage for directly controlling a 5.5Kw three-phase squirrel cage asynchronous motor is below 440V, and the rated working current is 12A
LX918-11X limit switch



The LX918 series limit switch is used in AC/DC 500V circuits to limit the travel of various mechanisms. Its shell material is zinc alloy, and it is surface galvanized and coated to prevent seawater corrosion. All exposed metal parts are made of stainless steel, and mechanical rotating parts are made of wear-resistant materials. The sealing components of the switch have the characteristics of resistance to oil pollution and service life.
