The TAKEX PR‑5B is a compact and discreet indoor photoelectric beam sensor designed for short-range applications where traditional dual-ended beam sensors are not practical. With a 5 m detection range and reflector-based design, it is ideal for entranceways, corridors, staircases, and passageways where quick and reliable “beam break” detection is needed.
Featuring a mirror lens, SPDT (Form C) dry contact output, and enhanced external light immunity, the PR‑5B offers high performance in a slim white housing that blends seamlessly into modern interiors. It operates on 10.5–26V DC, supports wall mounting, and is built for fast, forgiving installation—perfect for both residential and commercial alarm systems.

Frequently Asked Questions (FAQs)
Q1: What is the maximum detection range of the PR‑5B?
A1: The PR‑5B provides a detection range of up to 5 metres (16.5 feet) using a reflector-based infrared beam.
Q2: Does the PR‑5B require wiring to both ends?
A2: No. The PR‑5B uses a reflector system, meaning only the sensor side requires wiring—ideal where cabling to both ends is impractical.
Q3: What type of output contact does it provide?
A3: The sensor includes a Form C SPDT relay, offering both Normally Open (N.O.) and Normally Closed (N.C.) contacts.
Q4: Can the PR‑5B operate in bright indoor environments?
A4: Yes. It features enhanced light immunity via a special internal filter that blocks interference from visible light sources.
Q5: What voltage does the PR‑5B operate on?
A5: The sensor operates on 10.5–26 VDC, compatible with most standard security panel power supplies.
Q6: Is the PR‑5B suitable for outdoor use?
A6: No. The PR‑5B is designed for indoor use only, such as doorways, hallways, and entrances.
