SECO-LARM - SD-927PWCQ - Wave To Open Sensor, White Plate

Product Overview

The SECO-LARM SD-927PWCQ is an infrared no-touch request-to-exit sensor featuring a white single-gang plate and white body, with an illuminated LED ring that shows green during standby and red when triggered. It activates by a hand wave within 2 inches (5 cm) and includes a 3A Form C relay (NO/NC/COM) for access control integration.

Key Configuration

• • Operating voltage: 12 VDC
• • Current draw: 50 mA @ 12VDC
• • Sensing range: up to 2" (5 cm)
• • Relay output: Form C (NO/NC/COM), 3A @ 12VDC / 3A @ 24VDC
• • Output time: 0.5 sec or as long as the hand is near the sensor
• • Reaction time: 10 ms

Key Features

The SD-927PWCQ is an infrared no-touch request-to-exit sensor that activates by a hand wave within 2 inches (5 cm), triggering a Form C relay for door release or device activation. The illuminated LED ring provides clear visual feedback — green during standby and red when triggered, with selectable color behavior to indicate activation status.

Technical Context

The 3A Form C relay (NO/NC/COM) supports magnetic locks, electric strikes, and automatic doors, with a minimum output time of 0.5 seconds or latching while the hand remains near the sensor. The 10ms reaction time ensures near-instant response, making it ideal for hospitals, clinics, cleanrooms, schools, and factories.

Installation Notes

The white single-gang plate (115 × 70 × 33.5 mm, 70g) operates from -20°C to 55°C on 12 VDC at 50mA, and mounts to a standard single-gang wall box with a quick-connect screw-less terminal block for simplified wiring. Included decals in English, Spanish, and French support multi-language installation, and the sensor is suitable for contamination-sensitive environments.
