Hytronik Flush Mount PIR Motion Sensor

The HIR21 is a compact PIR motion sensor designed for lighting control in commercial and other B2B settings. This version is intended for tri-level control and uses 1-10V dimming. Its flush mounting design helps it suit spaces where a low-profile sensor is preferred.

This model is specified as a tri-level control PIR sensor with 1-10V dimming. That makes it suitable for applications where stepped lighting response is required rather than simple on/off operation. The product description specifically identifies it as the 1-10V version.

The HIR21 is differentiated by its tri-level control capability and 1-10V version specification. It is also built in a compact flush mount format, which sets it apart from larger or more surface-prominent sensor designs. For buyers comparing options, those are the key model-specific distinctions provided for this unit.

The sensor is rated for operation from -20°C to 50°C, which supports use across a broad range of indoor commercial environments. Buyers should still confirm that their project conditions stay within that operating range. The unit also carries a 50,000-hour lifetime and a 5-year warranty.

The HIR21 has a power rating of 800 W and is finished in white. It is listed with a 50,000-hour lifetime, a 5-year warranty period, and a product weight of 1.0000 kg. These details help buyers assess fit for project requirements and maintenance expectations.

A compact flush mount PIR sensor like the HIR21 is well suited to projects that want motion sensing with a cleaner, lower-profile appearance. It can be a practical choice for commercial lighting applications where visible hardware should be minimized. Its white finish also supports use in spaces that call for a neutral look.
