OMRON Level Switches - 61F-GPN-BT / BC

OMRON Level Switches – 61F-GPN-BT / BC

OMRON Level Switches – 61F-GPN-BT / BC ตัวควบคุมระดับของเหลวที่สามารถใช้แบตเตอรี่ 24VDC ได้โดยไม่ต้องใช้แหล่งจ่ายกระแสสลับ โดยใช้หลักการแรงดันไฟฟ้าคลื่นไซน์ระหว่างอิเล้กโรดช่วยให้ตรวจจับได้อย่างเสถียรโดยปราศจากการกัดกร่อนทางไฟฟ้า

เอาต์พุตสามารถตั้งค่าได้ให้เปิดหรือปิด
สามารถปรับตั้งอินพุตให้อยู่ในช่วง 0-100 kΩ เพื่อให้เหมาะสมกับของเหลว
มีทั้งรุ่นรีเลย์และ PNP
มีไฟแอลอีดีบอกสถานะ

Features | Level Switches – 61F-GPN-BT / BC

Outputs can be set to self-hold at ON or OFF using special circuits.
Adjustable sensitivity, with an operating resistance range of 0 to 100 kΩ, allows use for a wide variety of liquids.
Relay contact chattering conventionally caused by waves eliminated using open collector output, reducing contact wear.
Meets CE marking and is a UL recognized component.
