A Wired Beam Sensor is an infrared security device that detects intrusions by sending signals through a wired connection when its beam is interrupted. Ideal for perimeter protection and gate safety in stable, high-security installations.
A Wired Beam Sensor is a security device that uses invisible infrared (IR) beams between a transmitter and a receiver to detect movement or intrusion. When an object interrupts the beam, the sensor sends a signal through a wired connection to an alarm system, control panel, or automation system.
These sensors are widely used for perimeter security, gate/door safety, and intrusion detection. Because they rely on physical wiring for power and signal transmission, they offer stable, interference-free operation, making them ideal for high-security or industrial environments.
| Property | Typical Value / Range |
|---|---|
| Detection range (distance) | 30‑60 m or even up to ~100 m in open line‑of‑sight conditions outdoors. Mtech - Best Electronics in Kenya+2GUNMANSA+2 |
| Beam configuration | Single beam or dual beam. Dual beam tends to reduce false alarms (two beams must both be broken). Mtech - Best Electronics in Kenya+2GoldSupplier+2 |
| Wireless frequency | Often 433 MHz (or similar for remote wireless alarm systems) for transmitter → receiver / alarm panel communication. GoldSupplier+2GUNMANSA+2 |
| Power supply | Battery powered (sometimes rechargeable or solar assisted), or DC input (e.g. 12V DC) for both transmitter and receiver. GoldSupplier+1 |
| Current consumption | Low standby current (often µA‑mA range), higher current when transmitting / in alarm state. GoldSupplier |
| Output / signal | Usually a relay output (Normally Open or Normally Closed) for alarm, possibly wireless signaling to a control panel. Some models have tamper or masking detection. GoldSupplier+2Mtech - Best Electronics in Kenya+2 |
| Operating temperature / environment | Quite wide: from around ‑20 °C up to +50/60 °C depending on model. Weather protection ratings (IP54, IP55, etc.), resistant to dust, rain, sometimes to insects. patsecuritysolutions.co.ke+2GUNMANSA+2 |
| Installation / mounting | Adjustable brackets, ability to align beam properly (horizontal / vertical adjustment). LED indicators often provided to help with alignment. Weatherproof housing. patsecuritysolutions.co.ke+2Mtech - Best Electronics in Kenya+2 |
| Response / trigger time | Fast — usually tens to a few hundred milliseconds. |
