D4NH-4CAS

Snap Action, Limit Switches

The D4NH-4CAS is a snap action, limit switch, and is a part of the non-contact sensing device product offering. It is an ideal choice for accurate and reliable position sensing in most automated processes, due to its highly reliable and robust construction. This snap action, limit switch offers extended service life, performance as well as various mounting options.

Application Field

The D4NH-4CAS is used in a variety of applications, including transportation equipment, agricultural machinery, packaging equipment, industrial automation, and robotics. In addition, it is suitable for use in hazardous environments, due to its flame retardant, sealed construction. This snap action, limit switch can be used as a safety device for emergency stop, limit monitoring and detection, or as a control switch for automatic operation.

Construction

The D4NH-4CAS is a thermoplastic snap action, limit switch with a sold item size of 4 pin. It has a red indicating light that increases user visibility. The switch is designed for continuous operation, with a maximum operating temperature of 100°C. Its contacts are designed for easy, long-term performance and for reliable position sensing. The actuator is gold plated, providing reliable electrical contacts that can be relied upon even in extreme environments. The switch is certified to UL/CSA, EN/IEC and ROHS standards, providing high quality and reliable performance.

Working Principle

The D4NH-4CAS uses an integrated, accurate snap action mechanism to precisely sense the position of an automated process. The snap action is triggered when a certain force is applied, causing the actuator to pivot, and then snap back into place. This snap action triggers the contacts, allowing a signal to be sent to the process control system. The D4NH-4CAS is designed for accuracy, as the actuator’s pivot point is designed to be adjustable, allowing for precise calibration. The switch presents a reliable, compact and economical solution for position sensing in a wide range of processes.

Conclusion

The D4NH-4CAS is a reliable and robust snap action, limit switch, designed for accurate position sensing in automated processes. Its robust design and certified standards ensure long-term performance, even in extreme conditions. It is certified to UL/CSA, EN/IEC and ROHS standards, providing high quality and reliable performance.
