Rexroth GIV50-11 Position and Limit Switch Assembly for Hydraulic and Automation Systems

Product Overview

The Rexroth GIV50-11 is a position switch assembly (also known as a limit switch assembly) designed for use in hydraulic cylinders, industrial linear actuators, and automation systems where end-position detection is required. This assembly is commonly used with Rexroth's proportionally controlled hydraulic valves and cylinders. It provides electrical feedback when a movable component reaches a predefined position, enabling precise control of stroke limits and sequence operations. The GIV50-11 is built for durability in harsh industrial environments, including steel mills, heavy machinery, and mobile equipment.

Key Features of GIV50-11

The assembly includes one or more mechanical or inductive limit switches housed in a robust metal enclosure. The GIV50-11 is typically equipped with a roller lever actuator, which is tripped by a cam or stop surface on the moving part. The switch contacts are rated for 250 V AC / 24 V DC, with a switching current of up to 5 A. The assembly is designed for mounting on hydraulic cylinders or linear guides, with a standardized interface compatible with Rexroth's MG and other cylinder series. The degree of protection is IP67, making it suitable for use in wet, dusty, and high-vibration environments.

The GIV50-11 is available with different switch configurations (e.g., 1 NO + 1 NC, or 2 NC). The specific part numbers MC 224264 and R900764259 refer to alternative manufacturer numbers for the same or similar assembly. The operating temperature range is -20 to +80°C. The assembly includes a pre-wired cable or a terminal block for field connection. The switch mechanism is sealed against moisture and contamination. The GIV50-11 is designed for ease of replacement in the field, with straightforward mounting and adjustment procedures.

Functional Description

The GIV50-11 is installed on a hydraulic cylinder or linear actuator such that a moving cam or stop contacts the roller lever when the actuator reaches a predetermined position. The mechanical motion flips the switch contacts, sending a 24 V DC signal (or opening a circuit) to the PLC or control system. The PLC then uses this signal to stop motion, change speed, or initiate the next sequence step. The IP67 rating ensures reliable operation even in wet or dusty conditions common in foundries, steel plants, and outdoor equipment.

Applications

The Rexroth GIV50-11 is used in hydraulic press systems, injection molding machines, steel mill equipment, mobile hydraulics, and automated machine tools requiring precise end-of-stroke detection.
