SMC 2-Wire Open End Cable Band NC Reed Pneumatic Switch D-C7 Series, 24V dc LED Indicator

SMC D-C7 Series Pneumatic Switch, 24V DC Voltage, NC Operation Type - D-C73C

This pneumatic switch is a compact, band-mounted reed sensor designed to detect piston position in pneumatic cylinders and provide a compatible PLC input. It operates as a normally closed device with a 2-wire open-end cable and includes an LED for visual status. The unit is intended for industrial control environments and meets recognised electrical and environmental standards for sensor use.

Features and Benefits:

• 24V DC supply supporting common control systems
  Switching current rated at 40mA for small-load interfacing
  IP67 protective construction for wet or dusty environments
  Reed-type contact suitable for magnetic actuation detection
  Works across -10 to 60°C for broad operating conditions

Applications

• Suitable for monitoring cylinder end-of-stroke positions
  Ideal for integration with PLC inputs in control panels
  Used with band-mount actuators on CD76 and CD85 cylinders
  Can be employed where waterproof sensors are required
  Appropriate for compact installations requiring small sensors

What electrical connection is provided for field wiring?

It uses a 2-wire open-end cable configuration for straightforward connection to PLC inputs or relay circuits.

How does the unit indicate detection status on-site?

An integrated LED illuminates to show the switch operating state for quick visual checks.

Which environmental standard defines its ingress protection?

The sensor conforms to IEC529 ingress protection criteria and is rated to IP67 for waterproofing.

Can it tolerate industrial temperature swings?

The operational range spans from -10 to 60°C, accommodating typical factory ambient conditions.
