Limit switches are essential components in automated control systems where accurate positioning of actuators is required. In heating and plumbing installations, these switches are commonly used with mixing valves and control actuators to confirm the correct position of the actuator during operation. Installers and technicians working on building services systems, including heating, ventilation and sanitary applications, rely on such switches to ensure system reliability and safety. The integration of limit switches is particularly relevant in systems where precise control of flow and temperature is critical, such as in underfloor heating, domestic hot water systems and industrial process controls.

This IVAR limit switch is specifically designed for use with IVAR.ACTUATORS motors. It provides a mechanical or electrical signal when the actuator reaches a predefined position, allowing for integration with control panels or automation systems. The switch is typically mounted directly on the actuator housing and is used to confirm the open or closed position of the actuator, ensuring the system operates as intended.

Technical parameters

Code	1920745
Brand	IVAR

The technical parameters for this product are not provided in the brief. However, when selecting a limit switch for an actuator, factors include compatibility with the actuator model, signal type (mechanical or electrical), and the required switching force. The weight of the switch is 0.018 kg, which is relevant for handling and mounting considerations.

Installation and connection

The installation of the IVAR limit switch involves securing it to the actuator housing and connecting it to the control system. The switch is typically mounted using screws or clamps provided with the actuator. It is important to ensure the switch is aligned with the actuator's movement path to avoid misalignment or damage. During installation, the technician should verify that the switch is positioned so that it engages correctly at the desired actuator position. Common mistakes include incorrect alignment, which can lead to false signals or failure to trigger the switch, and improper tightening, which may cause the switch to become loose during operation.

Compatibility and accessories

This limit switch is compatible with IVAR.ACTUATORS motors. It is intended for use with mixing valves and control systems that require position feedback. When ordering, ensure that the switch is matched to the specific actuator model. No additional accessories are mentioned in the brief.

Technical background for designers

The IVAR limit switch operates by detecting the physical position of the actuator and providing a signal to the control system. It is typically made from durable materials suitable for use in industrial and building services environments. The switch is designed to integrate with the actuator's control circuit, allowing for automated system responses based on the actuator's position. The service life and efficiency of the switch depend on factors such as the of actuator movement, the force applied during operation, and the environmental conditions in which it is installed.

Service and operation

The IVAR limit switch requires minimal maintenance. Regular checks should include verifying the switch's alignment with the actuator and ensuring that the electrical connections are secure. If the switch fails to trigger correctly, it may indicate misalignment or wear. No specific service intervals are provided in the brief.

Frequently asked questions

Can the IVAR limit switch be used with other actuator brands?
There is no information in the brief to confirm compatibility with other actuator brands. The switch is specifically designed for IVAR.ACTUATORS motors.

Is the IVAR limit switch suitable for outdoor installations?
The brief does not specify environmental suitability. Installers should refer to the manufacturer's technical data sheet for details on operating conditions.

How is the IVAR limit switch connected to the control system?
The switch provides a signal when the actuator reaches a predefined position. The method of connection depends on the control system and should be verified during installation.

Can the IVAR limit switch be replaced without removing the actuator?
It is likely that the switch can be replaced without removing the actuator, but this should be confirmed during installation based on the actuator's design.
