Physical Dimensions and Construction

This keyboard measures 20.0 cm in length and 10.0 cm in width. Its total thickness reaches only 1.2 cm including the mounting flange. 6ES5982-3BA11 weighs just 0.28 kg for panel mounting. The polyester membrane surface resists oils, dust, and mild chemicals.

Moreover, a sealed aluminum backing plate provides mechanical rigidity. This plate also acts as an EMI shield for sensitive electronics. You can clean the front surface with mild detergents without damage.

Key Layout and Tactile Response

The 40 keys include 10 function keys and 30 alphanumeric keys. Each key provides positive tactile feedback upon actuation. A 200 g actuation force prevents accidental presses from vibrations. Laser-engraved legends resist wear from repeated use.

Electrical Interface and Connection

A 20-pin ribbon cable terminates in an IDC connector. This cable length measures 0.5 meters for flexible panel placement. The keyboard uses a passive matrix scanning design for reliability. An external driver module handles key decoding and debouncing.

Backlighting and Visibility

Yellow-green LED backlighting illuminates all keys evenly. This backlight operates from a 24V DC supply at 50 mA. You can dim the backlight using an external potentiometer. Consequently, operators can read key legends in dim control rooms.

Typical Application Scenarios

You can deploy 6ES5982-3BA11 in SIMATIC S5 operator workstations and control desks. It also works well for machine-mounted programming panels and HMI stations. This keyboard enters setpoint values, navigates menus, and acknowledges alarms. Its sealed design suits food processing and automotive assembly lines.
