The Pego MicroP is a magnetic door switch for cold room doors, signalling door open/closed status to the control panel. The contact is closed when the magnet is near the sensor (door closed) and no calibration is required. Compatible with all Pego electronic controllers and panels with a low-voltage digital input, including the ECP202 Expert. Operating temperature -20°C to +90°C. Simple surface-mounted installation on the door and frame.
