Photocells Nice Proxima PMBH for Hörmann — H‑type bus connection

Nice Proxima PMBH photocells for Hörmann are safety sensors designed to detect presence and interruptions in the path of automatic doors and gate systems. These photocells integrate with Hörmann control units via the H‑type bus connection (H‑bus) and are suitable for indoor and covered outdoor installations. The device monitors the movement area of sectional doors and gate operators to help prevent collisions and ensure safer operation.

How to use

Install the transmitter and receiver so the infrared beams align across the area to be monitored, following Hörmann installation guidelines for H‑bus connected accessories. Connect the units to the Hörmann control unit via the H‑type bus wiring, ensuring secure terminals and correct polarity where applicable. After mechanical mounting and electrical connection, perform system alignment and a functional test using the gate or door control panel to confirm that beam interruption triggers the expected safety response. Periodically inspect the lenses for dirt or obstruction and clean with a soft, dry cloth as needed.

Usage recommendations

For reliable long-term operation, mount the photocells in sheltered locations away from direct water exposure and heavy dust. Use them in conjunction with compatible Hörmann control units and follow the manufacturer's wiring and commissioning instructions to ensure correct H‑bus integration and safety function.
