The SD sensor from ZF Friedrichshafen AG succeeded in winning business from two of the leading forklift manufacturers in China. ZF’s SD74 series have been installed on the forklift to test speed and direction.
Speed and direction sensors of the SD series have been designed to detect ferromagnetic structures. A modular-based design allows the pre-selection of key criteria including shaft length and output interface, for example. Supplied with a plastic housing and mounting flange, all standard parts meet the IP67, and notably IP69 for harsh environmental conditions with ingress protection at depths of 20 to 60 mm.
The modular design offers users a range of housing lengths of 20, 35, 45 or 60mm with alternative shaft lengths available on request (up to 80 mm). Key features include measurements from near zero up to 20KHz, variable shaft diameter (12 to 20 mm), 2-wire, 3-wire or 4-wire output, rotatable shaft head (to determine angle of wire outlet), flexible wire orientation (horizontal or right-angle), available with open-collector, PWM or current signal outputs, typical air gap 0.3–2.2 mm (target dependent). Options available upon request are cable interface (connector upon request) and wire harness option with customer-specific connector.
Typical applications include electric drives (stationary and mobile), automation systems, conveyor belts, and wind turbines.
At electronica from 11th to 13th July in Shanghai (Booth No. 6.2D102), ZF will present its range of different sensor types.
