Omron D4A-N Series Limit Switch, IP67, 10A Switching Current - D4A-1116N


This limit switch is a Compact industrial device for detecting mechanical positions and actuating control circuits in harsh environments. It is designed for general-purpose automation and offers sealed construction and multiple actuator options to Interface with moving parts. The unit is intended for installation where robust electrical switching and a small footprint are required.

Features & Benefits


• IP67 sealed enclosure provides protection against dust and immersion
• Rated for switching up to 600V and 10A for high-voltage control
• Coil spring actuator delivers low operating force of 1.47N
• Mechanical endurance of 50 million operations reduces replacement frequency
• Wide ambient range supports operation up to 100°C
• Conduit entry accepts 1/2in-14NPT for standard industrial cabling

**Applications**


• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for motor direction selection and speed control feedback
• Used with packaging machinery for position sensing under washdown
• Can be used for safety interlocks in heavy equipment panels
• Suitable for rotary cam and camless actuation monitoring

What sealing and mounting features help maintain performance in wet conditions?


The head incorporates a double-seal arrangement and a full gasket cover to meet NEMA-style protection and an IP67 degree of protection when correctly installed.

Which contact arrangement and contact type are provided for control logic flexibility?


The switch uses a single-pole double-throw contact configuration with double-break contacts to offer clear changeover switching for control circuits.

How does the unit support different indicator or conduit options?


The design allows selection of indicator lamp types or variant switch boxes and can be supplied with alternate conduit threads on request to suit installation needs.

What are the electrical insulation and dielectric performance characteristics?


Insulation resistance is specified at a minimum of 100MΩ at 500V DC and dielectric strength tests include 1000VAC between like terminals and 2200VAC between live parts and earth for one minute.

What maintenance or service guidance applies to field replacement?


The block-mount construction permits the head, switch body and receptacle to be ordered and replaced individually to reduce downtime.
