QDID4/0N-0A IMO Photo-Electric Switch Block Diffuse Reflection, 2m Cable

Why Choose the IMO QDID4/0N-0A Photo-Electric Switch?

The IMO QDID4/0N-0A is a compact direct diffuse photoelectric sensor from the IMO QD Series, designed for reliable non-contact object detection in industrial automation and machinery. Its miniature block-style housing makes it particularly useful where installation space is limited while still providing a substantial sensing distance.

Using an infrared light source, the QDID4/0N-0A detects light reflected directly from the target, eliminating the need for a separate reflector or receiver. It offers an adjustable sensing distance of up to 1,500 mm and provides an NPN NO/NC output with light-on and dark-on operation for flexible connection to PLCs and industrial control systems.

The sensor is supplied with a 2 m pre-wired cable for straightforward installation. Its compact PA66 plastic housing measures approximately 31.2 × 12.8 × 21 mm and provides IP67 protection, making the QDID4/0N-0A a practical choice for conveyors, packaging equipment, assembly machinery and general factory automation.

Compact Direct Diffuse Detection for Industrial Automation

Direct diffuse photoelectric sensing places the emitter and receiver in the same housing. The QDID4/0N-0A emits infrared light towards the target and detects the portion reflected back from its surface. When sufficient reflected light is received, the sensor changes its output state, enabling object presence and position to be detected without physical contact and without requiring a separate reflector.

The IMO QD Series is designed around compact photoelectric sensing for industrial machinery. With its 1,500 mm adjustable detection distance, NPN NO/NC output, miniature housing and pre-wired cable, the QDID4/0N-0A is particularly suited to conveyor, packaging, sorting and assembly applications where simple installation and compact dimensions are important.

Typical Applications

• Conveyor product and package detection.
• Packaging and wrapping machinery.
• Component presence and position monitoring.
• Automated assembly equipment.
• Sorting and material handling systems.
• Product counting on production lines.
• General OEM machinery and factory automation.
