Takex PB-100TK Twin Beam Detector 100m

Takex PB-100TK Twin Beam Photoelectric Detector

Overview

The Takex PB-100TK is a dual-beam photoelectric detector engineered for outdoor perimeter protection and intrusion detection applications. Designed for long-range coverage, this twin beam unit operates across a 100-meter detection span, making it suitable for fence lines, property boundaries, and building perimeters requiring extended surveillance zones. The PB-100TK combines optical beam technology with weatherproof construction, delivering reliable boundary detection in demanding outdoor environments.

Key Features

• 100-Meter Detection Range: Twin beam configuration covers extended outdoor distances, reducing the number of units required for larger perimeter installations
• Twin Beam Design: Dual photocells provide redundancy and false-alarm filtering by requiring both beams to be interrupted for alarm triggering
• IP66 Rating: Fully sealed enclosure provides protection against water jets and dust ingress, maintaining performance in rain, spray, and high-humidity conditions
• Outdoor-Grade Construction: Purpose-built for exterior deployment with weather-resistant materials and sealed optical window
• Photoelectric Technology: Proven infrared beam methodology for perimeter intrusion detection without moving parts
• Long Service Life: Solid-state photoelectric sensors require minimal maintenance and avoid mechanical degradation
• Integration Ready: Compatible with standard security control panels and alarm systems via normally open/closed relay outputs
• Easy Alignment: Passive infrared transmitter and receiver design simplifies field installation and commissioning

Deployment Environment

The Takex PB-100TK is specifically engineered for outdoor installation. The IP66 rating ensures the unit withstands heavy rain, spray from irrigation systems, and harsh weather conditions common in perimeter security applications. The twin beam configuration makes it suitable for fence-line detection, parking area boundaries, and building exterior protection where extended coverage distance is required. Integrators should position the transmitter and receiver units with clear line-of-sight alignment across the protected zone.

Technical Specifications

Detection range extends to 100 meters with the twin beam design. The IP66 rating certifies the enclosure against water and dust penetration, critical for outdoor reliability. The photoelectric detection method operates continuously without moving parts, eliminating mechanical maintenance concerns. Twin beam redundancy reduces false alarms caused by temporary obstructions such as vegetation or light precipitation.

Installation Considerations

The PB-100TK requires line-of-sight between transmitter and receiver across the entire detection zone. Integrators should mount units at consistent heights and angles to maintain beam alignment. The sealed optical window design accommodates outdoor mounting without separate protective covers. Standard relay outputs connect to compatible alarm control panels, allowing the detector to trigger zones and integrate with existing security systems.

Karl Wilson

During recent perimeter security planning, I evaluated the Takex PB-100TK for a large commercial property requiring extended boundary detection. The 100-meter range eliminates the need for multiple detector units across standard fence lines, and the IP66 rating proved critical for weatherproofing in this installation. The twin beam design delivers practical false-alarm filtering by requiring simultaneous interruption of both beams before triggering an alarm.

Technical Highlights:

• 100m Detection Range: Twin photoelectric beams achieve extended coverage, reducing unit count and installation complexity for long perimeter runs
• IP66 Weatherproofing: Sealed optics and enclosure maintain detection reliability through rain, spray, and humidity without degradation
• Redundant Beam Logic: Dual-beam interruption requirement filters transient obstructions and vegetation movement, minimizing nuisance alarms

Deployment Considerations:

• Verify unobstructed line-of-sight alignment between transmitter and receiver units before final installation
• Mount units at matching heights to maintain consistent beam geometry across the detection zone
• Integrate relay outputs into compatible alarm panels configured for perimeter zone monitoring
• Plan seasonal maintenance checks to verify optical window clarity and alignment, particularly in dusty or high-pollen environments

The PB-100TK delivers straightforward, reliable long-range perimeter detection for security integrators needing extended coverage with minimal infrastructure. The outdoor construction and weatherproofing make it immediately deployable in demanding field conditions, and the twin beam architecture reduces false alarm risk inherent in single-beam systems.
