Introduction to the TAKEX PB-200FA Quad-Beam Perimeter Sensor
The TAKEX PB-200FA is a purpose-built long-range outdoor quad (4-beam) photoelectric perimeter sensor designed to provide reliable intrusion detection up to 200 m per beam. Combining double‑modulated infrared pulsed LEDs, phase‑locked tuning, programmed AGC with Auto‑Gain Lock (AGL) and AND‑gating across its four beams, the PB-200FA is engineered to minimise nuisance alarms from small animals, foliage and changing light conditions while delivering stable detection in rain, fog, snow and direct sunlight. Housed in an IP55-rated resin body with a polycarbonate cover and offering flexible outputs for integration, it is intended for demanding perimeter protection tasks where wide coverage and robust operation are priorities.
Key features at a glance
- Long-range detection:200 m outdoor protection per beam (with a quoted maximum arrival distance of ~2,000 m under ideal conditions).
- Quad-beam AND gating:Four independently received beams are AND‑gated to reduce false alarms from small animals or isolated obstructions.
- Advanced beam stability:Double‑modulated pulsed IR, phase‑locked tuning and AGC/AGL for resistance to sunlight, rain and other environmental disturbances.
- Flexible integration:Selectable dry‑contact alarm output (NO/NC) and tamper contact for direct connection to alarm panels, access control or CCTV systems.
- Installer-friendly alignment:±90° horizontal and ±10° vertical adjustment, audible alignment tone, monitor jack and LED indicators to speed commissioning.
- All‑weather housing:IP55-rated enclosure (resin body, polycarbonate cover) rated for −35 °C to +66 °C operation.
Detailed specifications and benefits
Understanding the PB-200FA’s specifications helps explain why it performs well in real-world perimeter security deployments.
- Detection distance:200 m per beam for typical outdoor applications. This distance makes the PB-200FA suitable for protecting wide open spaces and long perimeters with relatively few sensor heads.
- Maximum arrival distance:The datasheet quotes an approximate arrival distance of ~2,000 m under ideal conditions — this figure reflects the total optical path arrival capability and should be interpreted conservatively for practical installations where vegetation, heat shimmer or heavy precipitation are present.
- Double‑modulated pulsed IR LEDs & phase‑locked tuning:These technologies maintain a stable, high‑contrast optical link and reduce susceptibility to ambient light interference such as sunlight reflection, headlights or flashing signs.
- Quad-beam AND gating:All four beams must be interrupted for an alarm condition (AND logic), which greatly reduces false alarms caused by small animals, passing debris or temporary small obstructions.
- Adjustable response time:The response time is adjustable (0.05–0.7 s, default 0.05 s), allowing installers to balance detection speed versus immunity to transient obstructions or environmental noise.
- Power supply:Wide input range, 12–30 V DC (non‑polarity), making the device compatible with many typical security system power arrangements.
- Alarm & tamper outputs:Dry contact relay for alarm (selectable NO/NC) and a tamper contact (NC) for enclosure protection — both suited for direct integration with alarm control panels, CCTV event inputs or building management systems (confirm relay ratings in the datasheet when connecting external devices).
- Connection and relay capacity:Typical relay capacity is in the small signal range (≤30 V AC/DC, ~0.5–1.0 A) — suitable for signaling but consult the installation manual for wiring details and limits before switching larger loads.
- Alignment aids:Audible alignment tone, monitor jack and LED indicators speed up commissioning and alignment, reducing installation time on long runs.
- Durability:Resin body and polycarbonate cover with IP55 rating provide protection from dust and water jets, and operation across a wide temperature range (−35 °C to +66 °C) ensures year‑round use in many climates.
Use cases and scenarios where the PB-200FA excels
The PB-200FA is geared for sites that require reliable first‑line intrusion detection across long, exposed perimeters. Typical deployments include:
Large industrial yards and logistics hubs benefit from the 200 m beam range because fewer devices are needed to cover long stretches of open perimeter. The quad‑beam design helps reduce nuisance alarms from birds or wind‑blown debris common in these environments.
Power stations, water treatment plants and substations often need early detection ahead of fences and gates. The PB‑200FA can be used as a first line of detection to trigger cameras, lighting or lock‑down procedures before an intruder reaches sensitive equipment.
For remote or rural sites with long fences, the long range and AND‑gating minimize false alarms from wildlife and provide actionable alerts without the cost of dense sensor networks.
Integrate the PB‑200FA’s alarm output with PTZ camera presets to automatically cue cameras towards an intrusion point for immediate visual verification — a low‑cost, effective way to increase situational awareness.
Comparisons with similar products on the market
When evaluating long‑range perimeter beams, buyers typically compare range, false‑alarm immunity, weather robustness, output flexibility and ease of installation. The TAKEX PB‑200FA stands out in several of these areas:
- Range vs. compact beams:At 200 m per beam, the PB‑200FA serves longer spans than many compact single‑ or dual‑beam units that are optimised for short fences or building‑edge protection.
- False-alarm rejection:Quad‑beam AND‑gating delivers stronger immunity to animal‑ or debris‑triggered false alarms than single‑ or dual‑beam systems. Curtain‑style beams or dense multisensor arrays may offer different tradeoffs (finer granularity vs. increased hardware and cost).
- Environmental resilience:Double‑modulated pulsed IR and AGC/AGL tuning give the PB‑200FA robustness in bright sun and adverse weather — a competitive advantage versus simpler photoelectric beams that can be vulnerable to sunlight or heavy precipitation.
- Integration flexibility:The selectable NO/NC dry contacts and tamper output make wiring straightforward. Buyers needing heavy power switching should verify relay ratings and consider external interface devices or contacts.
In short: compared with broad market alternatives, the PB‑200FA is positioned as a solid choice for long‑range, low‑false‑alarm perimeter protection. For installations where ultra‑fine detection zoning is required (e.g., short setbacks with dense obstructions), alternative curtain or fence‑mounted sensors might be preferred; conversely, for long open perimeters the PB‑200FA often reduces equipment and commissioning overhead.
Customer testimonials and installer feedback
Official public customer reviews for this model may be limited in third‑party marketplaces. Below are illustrative, anonymised installer and end‑user impressions based on typical field experience with long‑range quad‑beam detectors and TAKEX products (presented as typical feedback rather than verified customer quotes):
- "Alignment tools like the audible tone and monitor jack cut commissioning time significantly on long runs — especially on uneven terrain where frequent repositioning is required."
- "Quad‑beam AND gating dropped our nuisance alarm rate compared with older single‑beam units, so the security team could focus on genuine events rather than chasing false alerts."
- "The broad operating temperature range and IP55 housing meant reliable performance year‑round at an outdoor substation — we had no major environmental‑related failures in two seasons."
If you need verified customer case studies or local references, ask your TAKEX distributor or installer for documented examples or site references in similar industries.
