Panel module with four mechanical buttons

An outdoor module that adds 4 mechanical buttons to a modular panel system. The aluminum alloy body combines IK07 impact resistance with IP65 dust and water protection. It draws power from the other modules and passes 5 V DC to the modules on the same line.

Key features

Four mechanical buttonsThe module combines 4 mechanical buttons in a single body.

Aluminum bodyThe aluminum alloy casing protects the module against outdoor conditions.

Modular powerIt draws power from the other modules and feeds 5 V DC to the modules on the same line.

Flush and surface mountIt supports both flush mount and surface mount installation.

Low consumptionIt uses ≤0.2 W in standby and ≤0.6 W while working.

Outdoor durabilityIt works outdoors between -30 °C and +60 °C and withstands 10% to 90% relative humidity.

Installation requires silicone sealant; the IP65 rating depends on it.
