TE Connectivity VCS-04 Vertical Float Switch 43mm

The TE Connectivity VCS-04 Vertical Float Switch is a compact liquid level sensor with form-A SPST reed switching, designed for accurate liquid level detection.

Overview

The switch features a durable polypropylene body and a black glass-filled polypropylene housing and float. Its reed switch mechanism uses a ruthenium contact to provide form-A SPST (Single Pole, Single Throw) switching. The VCS series supports flexible top or bottom entry mounting and provides both high and low-level sensing.

Switching Configuration

The switching mode can be configured as normally open (N/O) or normally closed (N/C) by reversing the orientation of the float. As specified, the switch operates as N/C when the float is in the down position. This allows the switch to trigger alarms or control pumps based on rising or falling liquid levels.

Applications

The VCS-04 is suitable for monitoring a range of liquids, including water, coolants and certain chemicals. Typical applications include:

• Activating high or low-level alarms in water tanks and reservoirs
• Monitoring condensate levels in HVAC and refrigeration systems to prevent overflow
• Providing coolant level indication in industrial cooling systems and machinery
• Chemical level sensing for process control and safety

Specifications

• Operating temperature: -30°C to a maximum of 70°C
• Pressure rating: Up to 1.3 bar
• Electrical connection: Internal fitting with 2 x 22AWG 16/0.2mm PVC insulated cables, supplied stripped
• Wetted components: Wetted magnet

The VCS-04 Vertical Float Switch combines top or bottom entry mounting with configurable N/O or N/C switching for a range of liquid level monitoring applications.
