Langmatz Pedestrian Signal Requester EK 424 plus

The Langmatz Signal Requester EK 424 plus for pedestrians is an innovative product with tried and tested properties. Its multifunctional configuration options give you planning flexibility and keep your costs lower. The equipment is designed exclusively using capacitive sensors with a dynamic measuring principle. If any change occurs in the sensor’s request zone, such as gum being stuck to it or a film of ice, it incorporates the change into the resonant circuit when a pedestrian makes a request. The self-regulating resonant circuit does not trigger continuous operation.
