Cylinders & Actuators-Mountings and sensors-494-C shaped detectors

Product catalog summary

Features:
- The document describes a detector for actuators with "C" grooves, which is mounted to slide across the tube slot. It is a static non-contact proximity switch designed for pneumatic cylinders equipped with built-in permanent magnets.

Functional Description:
- The detector operates by sensing the magnetic field generated by a permanent magnet mounted on the piston. This field causes a change in the semiconductors’ resistors, leading to a current variation that increases resistance and generates a switching signal.

Magnetic Position Detectors:
- The detectors are designed for "C" grooves and are magneto-resistive (MR) in nature, specifically from the Series 494.

Electrical Characteristics:
- Operating voltage ranges from 10-28 VDC and 4.5-28 VDC.
- Maximum switching power is 0.6 W and 1.5 W.
- Maximum switching current is 4-20 mA and 50 mA.
- The detectors have 2 or 3 wires, with reverse polarity protection available only for the 3-wire version.
- No overload or short-circuit protection is provided.
- Voltage drop is 3.5V and 0.5V (at 50 mA).
- Maximum leakage current is 0.8 mA and 0.01 mA.
- Maximum allowable overvoltage is 30V DC.
- Sensitivity is 40 Gauss, with a response time of 1000 Hz and repeatability of 0.5 mm.
- Operating temperature ranges from -10 to +70 ºC.
- Housing material is ABS, and cable material is PVC.
- Degree of protection is IP67, with signal indication via a red LED.
- Approval includes CE and RoHS certifications.

Specifications:
- The detectors are available with different cable lengths and connection types, including 5-meter cables and 0.3-meter cables with M8 connectors.
- Weight varies between 12g and 50g depending on the configuration.
- Compatible with specific cylinder series, with product codes provided for ordering.

Accessories:
- Various accessories are available, including extension cables and connectors with specific catalogue numbers for ordering.

Connection Details:
- Detailed connection instructions are provided for both 2-wire and 3-wire configurations, including pin assignments and polarity observations.

Mounting Recommendations:
- It is advised not to subject the power supply cable to damaging traction or torsion during its service life.

MAGNETIC POSITION DETECTORS for "C" grooves magneto-resistive (MR) FEATURES • A detector for actuator with "C" grooves, mounted sliding across the tube slot. • Static non-contact proximity switch on pneumatic cylinders equipped with built-in permanent magnets. FUNCTIONAL DESCRIPTION When the permanent magnet which is mounted on the piston approaches the detector, the magnetic field it generates causes the semiconductors’ resistors to change.
