The 6461 Infra-Red Non-Contact Switch is available in various contact configurations.
The Herga 6461 Infra-Red Non-Contact Switch provides a modern and hygienic solution for activation without physical contact — ideal for environments requiring clean operation, safety, and durability.
Using infrared sensing technology, the 6461 detects a hand, finger, or object within a range of 75–100 mm (nominal), with special versions capable of up to 500 mm detection distance.
This switch eliminates the need for mechanical wear components, offering a maintenance-free, sealed solution for medical, industrial, and public use systems.

The 6461 switch is mounted behind a protective acrylic lens, fully sealed with water-resistant epoxy, ensuring protection from moisture and cleaning agents.
Its housing is designed without external joints, eliminating dirt buildup and allowing easy cleaning with disinfectants — perfect for medical, spa, food service, and public control systems.
The infrared beam is modulated to prevent false activation from ambient light.
Installation is simple: drill a mounting hole, insert the unit, and secure it with a rear nut.
The switch connects directly to control equipment or through a relay, with maintenance activation possible from over 5 meters away using a handheld transmitter.
