PCST24

Product catalog summary

Overview: The posichron® PCST24 is a rod-style magnetostrictive position sensor designed for hydraulic cylinders and level indicators. It features high protection class ratings, wear-free operation, and significant shock resistance.

Product Versions: Available in analog output (1 and 2 channels) and digital outputs (SSI and CANopen).

Specifications:

Mounting: Thread options include M18 x 1.5 and ¾"-16UNF.
Working Pressure: Up to 400 bar.
Measurement Range: 100 to 5750 mm, adjustable in 10 mm increments.
Output Options: Various voltage and current outputs with alarm features.
Resolution: 16-bit full scale, minimum 10 µm.
Sampling Rate: Up to 1 kHz.
Linearity: Ranges >500 mm: ±0.10% f.s.; ≤500 mm: ±0.5 mm.
Repeatability: ±3 µm.
Material: Stainless steel sensor rod and AlMgSi head.
Protection Class: IP67, optional IP69.
Temperature Range: -40 to +85°C.
Shock and Vibration Resistance: 50 g/11 ms, 100 shocks; 20 g 10 Hz-2 kHz, 10 cycles.
EMC Compliance: DIN EN 61326-1:2013.

Output Specifications:

Analog Outputs: U1 (0-10 V), U2 (0.5-10 V), U8 (0.5-4.5 V), I1 (4-20 mA).
Digital Outputs: SSI with Gray or Dual code, CANopen with optional terminating resistance.

Accessories: Includes connector cables and position magnets, with various designs available upon request.

Dimensions: Detailed dimensions are provided for different mounting and connector configurations, with emphasis on consulting the factory for guaranteed dimensions.

Specifications: The sensor operates with an excitation voltage of 18-36 V DC and a typical excitation current of 20 mA at 24 V DC. It supports a measuring rate of 1 kHz and offers a resolution of 50 µm. The sensor is designed to function within a temperature range of -40 to +85°C and provides protection against reverse polarity and short circuits. It complies with EMC standard DIN EN 61326-1:2013.

Signal Wiring: The sensor uses an M12, 8-pin connector for signal wiring. The pin configuration includes Excitation + (white), Excitation GND (brown), Signal 1 + (green), Signal GND (yellow), and optional Signal 2 + (grey). For CANopen and CANJ1939 interfaces, an M12, 5-pin connector is used with pins for Shield, Excitation +, GND, CAN-H, and CAN-L.

Output and Error Diagnostics: The sensor provides analog output signals with error diagnostics. In case of errors such as a missing magnet, the output can assume states like Alarm_HIGH, Alarm_LOW, or Alarm_HOLD. For SSI output, if a magnet is not detected, the position value defaults to maximum.

Digital Output: The sensor supports SSI and CANopen interfaces. The SSI interface operates with a clock frequency of 100 kHz to 1 MHz and uses Gray-Code or Dual-Code for data transmission. The CANopen interface follows the CANopen CiA 301 V 4.02 profile and supports up to 127 nodes with a transmission rate adjustable between 50 kBit to 1 MBit.

Connector Cables: Various connector cables are available, including M12, 8-pin and M12, 5-pin configurations, with lengths ranging from 0.3 m to 10 m. These cables are shielded and suitable for use in cable carriers with a maximum movement speed of 3 m/s and acceleration of 5 m/s².
