WS12

Product catalog summary

Overview: The WS12 Cable Extension Position Sensor is designed for precise displacement measurement up to 3,000 mm. It features a durable aluminum housing and offers multiple output options, including analog, SSI, CAN Bus, and incremental encoder outputs. Redundant versions and magnetic absolute encoders are available.

Specifications: The WS12 sensor supports measurement ranges from 100 mm to 3,000 mm with quasi-infinite resolution for analog outputs and up to 100 µm for digital outputs. It maintains a linearity of ±0.10% f.s., with an optional ±0.05% f.s. The operating temperature range is -20 to +85 °C, and it complies with EMC standards (DIN EN 61326-1:2013).

Output Options:

Analog Output: Includes potentiometer, voltage (0-10V), and current (4-20mA) outputs, with programmable options.
Digital Output: Offers SSI and CAN Bus outputs, with CANopen and SAE J1939 protocols, including redundant configurations.
Incremental Encoder Output: Provides resolutions of 10 pulses/mm or 5 pulses/mm depending on the measurement range.

Mechanical Features: The sensor is housed in aluminum with a stainless steel measuring cable, rated IP67 for dust and water protection. The weight ranges from approximately 1 kg for lengths up to 1,500 mm to 1.5 kg for longer lengths.

Installation and Connection: Utilizes an M12 connector with 5 or 8 pins, designed to withstand shocks (100 g/11 ms) and vibrations (20 g, 10 Hz-2 kHz).

Applications: Suitable for industrial applications requiring precise position measurement, including automation and control systems.

Additional Specifications: The document details specifications for various sensor models, including working resistance, scaling, stability, and protection features like reverse polarity and short circuit protection. EMC compliance is highlighted.

Signal Wiring: Provides detailed wiring instructions for M12 connectors, ensuring correct installation and operation.

Programming and Calibration: Describes programming start and end values using binary signals, allowing for non-volatile storage of scaling ranges and resetting to factory defaults.

Digital Interfaces: Covers digital interfaces such as ADSI and MSSI, including specifications on excitation voltage, current, clock frequency, and data format.

Analog Outputs: Details various analog output configurations, including voltage, current, measuring rate, and stability, with protection features and EMC compliance.

Redundant and Programmable Outputs: Discusses redundant outputs and programmable outputs for customer-defined scaling.

CANopen and SAE J1939 Interfaces: Details specifications for these interfaces, including communication profiles, node IDs, and transmission rates.

Incremental Outputs: Describes incremental interfaces, focusing on excitation voltage, output frequency, and short circuit protection.

Accessories: Lists accessories such as connector cables with M12 configurations, available in various lengths and suitable for 5-pin sensor connectors.

Order Codes: Provides order codes for 5-pin and 8-pin cables, CAN-Bus cables, T-connectors, and terminating resistors.
