The Keyence TA-340 Amplifier Unit is a versatile and reliable solution designed to provide stable amplification and signal conditioning in automation and sensing systems. Built with Keyence’s reputation for precision engineering, this unit is tailored to handle both high-speed applications and environments that demand robust, long-lasting performance.

One of the standout advantages of the TA-340 is its dual sensitivity adjustment system. With a sensitivity selector switch for quick coarse adjustment and a fine-adjustment trimmer for precise calibration, users gain a high degree of control over detection accuracy. This feature makes the unit suitable for processes where slight variations in material or environmental conditions could otherwise compromise signal stability. By offering flexible tuning, the TA-340 ensures consistent operation across a wide range of sensing tasks.

The amplifier unit is also designed with flexible output capabilities to accommodate different industrial setups. It provides two distinct output types: a solid-state NPN output capable of handling 100 mA at 40 V maximum, and a SPDT relay contact output rated at 250 VAC, 2 A. This dual-output approach makes the TA-340 highly adaptable, whether it is being integrated into low-voltage digital circuits or higher-power switching environments. Furthermore, the inclusion of both contact and solid-state outputs enhances its compatibility with legacy and modern systems alike.

In terms of response characteristics, the TA-340 offers fast switching options of 1 ms and 10 ms for the control output, allowing users to select the best speed-performance balance for their application. Additionally, the relay contact output includes a built-in OFF-delay of 65 ms, which is useful for reducing signal noise and preventing false triggers in unstable conditions. This timing control makes the TA-340 especially valuable in applications involving rapidly changing signals or mechanical delays.

The unit is engineered for industrial durability, with a rugged design that withstands harsh environments. It maintains reliable performance in ambient temperatures from 0 to +50 °C and relative humidity from 35% to 85% without condensation. Furthermore, its vibration resistance—rated for operation between 10 and 55 Hz with a double amplitude of 1.5 mm in all three axes—ensures stable operation in machinery subject to constant movement or vibration.

The TA-340 also prioritizes efficiency, with a maximum power consumption of only 5 VA, making it suitable for continuous operation without imposing unnecessary load on power systems. Its compact and efficient design contributes to reduced maintenance and long-term reliability, minimizing downtime in production environments.

Overall, the Keyence TA-340 Amplifier Unit delivers a blend of precision, flexibility, and durability. Its dual sensitivity control, multiple output configurations, rapid response capabilities, and rugged environmental resistance make it an excellent choice for a broad spectrum of automation applications. Whether used in high-speed detection systems, industrial machinery, or production quality control, the TA-340 ensures dependable performance and ease of integration.
