B-Command

Company Overview

B‑Command GmbH, founded in 1995 in Hamburg, Germany, delivers complete electrotechnical solutions for industrial and heavy machinery markets. Initially focused on crane switchgear, the company expanded into wind power limit switches and evolved further into slip rings and rotary encoders, offering over 20,000 customized solutions globally.

Rotary and Cross-Limit Switches

These switches are essential in controlling end positions and movement limits in conveyors, hoists, and cranes.

• FRM Series Rotary Limit Switches: Designed for industrial conveyance and crane applications. They feature adjustable cam ratios from 1:1 to 1:900, positive-end contacts, stainless steel shafts, and protection ratings up to IP66.
• FRS and FCN Series: Compact or combination cam switches with modular contact arrangements, suitable for gearboxes and machinery control.
• Cross-Limit Switches (Alpha, Beta, Lambda): Heavy-duty zinc die-cast or reinforced plastic units for crane trolleys. Configurable for slow-down or stop functions with two to four contacts and multiple cable-entry options.

Safety Limit Switches

B‑Command offers electromechanical safety limit switches with separate actuators. These switches feature:

• Positive opening contacts in compliance with EN 60947‑5‑1.
• Durable double-insulated housings rated at IP65.
• Mechanical and electrical locking options, with holding forces up to 1,200 N.
• Certifications including IMQ, CCC, and CE for global compliance.

Pendant Stations and Remote Controls

The company manufactures modular and customizable control pendants and radio remotes for machinery operation.

• Pendant Stations (Eco‑Line, Premium, Kappa, Lady, Stilo): Support multiple buttons, selectors, potentiometers, signal lamps, and safety interlocks in IP65 and IP69K variants.
• Radio Remote Controls (Jump, Joysys/Joyplus): Up to 33 channels, 80 m range, emergency-stop options, all in rugged IP65 enclosures.

Slip Rings and Encoders

B‑Command’s slip ring portfolio (RotarX, PRS, PRP, PMS, etc.) offers power and data transfer for rotating machinery:

• Hollow-shaft, pancake, fiber-optic, USB/HDMI, and custom variants.
• IP ratings from IP00 through IP69, customizable for signals, power, or media.

Their rotary encoders and potentiometers support motion control applications including positioning and feedback in extreme industrial environments.
