Laser distance motion sensor FiF DRL-60-12-9, black, for Ø60 flush box, 9–27 V DC, max load 4 A

The Laser distance motion sensor FiF DRL-60-12-9 is a compact detector designed for installation in a Ø60 flush box. It combines laser distance measurement with motion detection to control lighting circuits with a supply voltage range of 9–27 V DC and a maximum switched load of 4 A. The device is intended for use in stairways, corridors and other narrow passages where precise presence sensing and a discreet, flush-mounted appearance are required.

Advantages

The sensor integrates a laser distance sensor and a motion detector in a small form factor that fits a standard Ø60 flush box, which simplifies retrofit and new-installation mounting. Its wide operating voltage range makes it compatible with different DC lighting systems and low-voltage supplies. The unit offers reliable switching of loads up to 4 A and provides accurate distance-based detection to reduce false triggers from distant movement. The black housing provides a low-profile visual appearance when installed in interiors.

Suitable for

• Automatic lighting control on staircases and corridors
• Retrofit into existing Ø60 flush boxes in residential and light-commercial interiors
• Applications requiring combined motion and distance-based presence detection to limit activation to nearby users
• Low-voltage DC lighting systems and control circuits operating between 9 and 27 V DC

When it may not be suitable

The detector is not intended for switching high-current loads beyond its 4 A limit; use a separate relay or contactor for heavier loads. It is designed for installation in a Ø60 flush box and may not fit non-standard mounting types or shallow enclosures. Environments that require IP-rated, weatherproof outdoor sensors or intrinsically safe devices are outside its intended scope.

Key specifications

• Mounting type: flush installation for Ø60 flush box
• Supply voltage: 9–27 V DC
• Maximum switched load: 4 A
• Detection principle: laser distance measurement combined with motion detection
• Color / finish: black
• Typical applications: indoor stairways, corridors and passages

How to use

Install the sensor into a standard Ø60 flush box following local electrical codes and with the supply disconnected. Connect the DC supply and load conductors according to the wiring diagram provided by the manufacturer, ensuring the load does not exceed 4 A. Position the sensor so its sensing window has an unobstructed view of the area to be monitored; the device will use laser distance readings and motion detection to switch lighting automatically. Adjust any onboard or commissioning settings as required for sensitivity, detection distance or hold time, if such adjustments are available.

What to consider before purchase

• Confirm availability of a Ø60 flush box at the intended installation location
• Verify system supply is within 9–27 V DC and that expected load current does not exceed 4 A
• Ensure indoor use in dry locations unless additional protection or enclosures are planned
• Check compatibility with the lamp type or driver being controlled (LED drivers, transformers, etc.)

Usage recommendations

For reliable performance, mount the sensor at a height and angle that provides clear line-of-sight to the detection zone, avoid placing it behind decorative grills or deep recesses, and plan external switching for loads above 4 A. During commissioning, test the detection area in normal lighting conditions and adjust settings to prevent activation from distant traffic or reflections.
