***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth ABZMS-35-1X/120F050S-K24 (R901057913) is a sophisticated float switch designed to monitor and manage fluid levels within hydraulic systems. This device is adept at controlling tank fluid levels in small power units of types ABSKG...NG; 10, 20, and 30. It features two switching contacts with pre-set switching points at specified millimeters, ensuring precise operation and reliability. The ABZMS-35-1X/120F050S-K24 float switch operates with a maximum pressure tolerance and includes an electrical connector with a Connector pole, Mx, A-coded design for seamless integration into existing systems. The product has a specific length and offers an electrical connection that supports a supply voltage range from 8 to 70 V DC. Its weight is carefully calibrated to ensure proper buoyancy and operation. Equipped with two output signals, the switch can handle various hydraulic fluids including HLP, HFAE, HFC, HFDR, HFDU, HETG, HEES, and HEPG. The device's functionality relies on the movement of the float which contains permanent magnets that activate reed contacts—normally closed and normally open—when reaching certain levels during fluid level changes. Additionally, this model can be equipped with temperature contacts as an option for monitoring maximum hydraulic fluid temperature. However, it's important to note that this feature is intended for shutdown functions rather than continuous temperature control. In summary, the Bosch Rexroth ABZMS-35-1X/120F050S-K24 float switch is a reliable component for hydraulic systems requiring precise fluid level management and offers added functionality with its optional temperature monitoring capability.

FLOAT SWITCH ABZMS-35-1X/120F050S-K24

Float switch

Unpacked Weight: 0.06461 kg

Float switches are switching devices operated by a float moved by fluid. They are used to control the tank fluid levels in small power units type ABSKG ... NG10; 20; 40 and 60.

The sliding tubes contain two fixedly set reed contacts (normally closed contact and normally open contact) that are switched by the permanent magnets installed in the float.

Fixedly set temperature contacts (option) are fitted to monitor the max. hydraulic fluid temperature.

Function of level switch

When the float reaches the switching points while the oil level is falling, the contacts are operated magnetically. The switching positions of the contacts are maintained until the float passes the switching points again due to a rising oil level.

Switching point L1 is a normally closed contact, the contact function of switching point L2 is optionally a normally closed or normally open contact.

Level switch function

Switching point L1 is a normally closed contact, the contact function of switching point L2 is optionally a normally closed or normally open contact.

Temperature contact function

A bimetal plate, which is influenced by temperature, switches when a firmly set response temperature is reached. The temperature contact is not suitable for temperature controlling, but merely for a shutdown function.

Float switches are switching devices operated by a float moved by fluid.

Installation information

Vertical installation according to technical data (see “Technical data”) Avoid flows Do not expose the switch to heavy impacts and bends Avoid external magnetic fields. Thus, the function of the reed contacts may be impaired.

Electrical connections:

Electrical connections may only be established by specialists Tighten the round connectors M12 x 1 and/or mating connectors after connection Only plug in the round connectors M12 x 1 and/or mating connectors in the de-energized condition Do not overload the contacts (see “Technical data”) In case of inductive load provide a protection circuit!
