Cylinders & Actuators-Mountings and sensors-494-reed switch type

Product catalog summary
Overview: This document provides technical specifications and guidelines for the use of magnetic position detectors, specifically reed switch types, designed for 'T' grooves in industrial applications.
Specifications:
  • Switching Power: Maximum DC = 5 W, AC = 5 VA
  • Switching Voltage: Refer to detailed specifications
  • Switching Current: Maximum 100 mA
  • Protection: No short-circuit or overload protection; reverse polarity protection is available without LED function
  • Voltage Drop: Less than 5 volts (EN 60947-5-2)
  • Breakdown Voltage: 230 V DC
  • Contact Resistance: Maximum 0.2 ohm
  • Insulation Resistance: 108 ohms at 100 V
  • Sensitivity: 2.1 mTesla (21 Gauss)
  • Response Time: 0.1 ms opening, 0.6 ms closing
  • Repeatability: Less than ± 0.2 mm
  • Working Temperature: -25°C to +70°C
  • Housing: PA + FG overmolding
  • Cable: PUR, resistant to cutting oils
  • Protection Degree: IP67
  • Protection Class: Cable outlet: Class II, M8 and M12 connection: Class III
  • Approval: CE
  • Signal Indication: Yellow LED lights up when contact is established
Functional Description: The detector uses a permanent magnet mounted on the piston of an air cylinder to activate the reed switch. It is designed for direct fitting on 'T' cylinder grooves and requires a fixation kit for certain models.
Choice of Detector: Available for voltage ranges of 5 to 120 Volt AC/DC and 5 to 60 Volt DC. Various connection options are available, including PUR leads and M8/M12 connectors.
Electrical Characteristics and Protection: Maximum switching current is 100mA. External protection is recommended for inductive loads to prevent damage from voltage peaks.
Applications: Suitable for direct control of incandescent lamps, with considerations for cold lamp resistance. For leads longer than 10 m, a 200 Ω resistor is recommended to reduce capacitive effects.
Accessories: Includes extensions and connectors with IP67 protection, and a block for memorizing the position of the adjustment detector.
Mounting Recommendations: Avoid subjecting the detector's power supply cable to damaging traction or torsion during its service life.

MAGNETIC POSITION DETECTOR FOR " T " and DOVETAIL GROOVES - REED SWITCH TYPE MAXIMUM ELECTRICAL CHARACTERISTICS AND PROTECTION OF MAGNETIC DETECTOR (REED SWITCH) Maxi switching current : 100mA For inductive loads (valves, contactors, …), external protection is required to avoid damage caused by switch-off voltage peaks. Use freewheeling diode, transil diode, varistor or similar. PARTICULAR APPLICATIONS (valid for all models) • Detectors used for direct control of incandescent lamps: The capacity specified on the lamp is based on its resistance when hot. When switched on, the resistance of the...
