This is the Danfoss KPS39 060 - 410466 pressure switch, a part of the Switches and thermostats product series. It comes with switch accessories and is packaged in an industrial - grade manner, with 12 units per pack. Pressure - related Features The pressure switch has a G - type pressure connection with a size of 1/4, following the ISO 228 - 1 standard and featuring internal - threaded connections. The pressure - sensing element is a bellows, ensuring accurate and reliable pressure detection. The adjustment range spans from 10 to 35 bar (1 - 3.5 MPa or 145 - 508 psig), and the hysteresis is between 2 - 6 bar (29 - 87 psi). It has an automatic reset function, which is convenient for continuous operation. The maximum working pressure is 45 bar (653 psig), and the maximum test pressure is 53 bar (769 psig). Electrical Specifications For electrical connection, it uses a cable thread connection with a size of Pg 13.5 and an internal - threaded form. It comes with a metal cable gland and adheres to the DIN 40430 standard. The contact function is SPDT with gold - plated contacts, which offer enhanced conductivity and durability. The contact ratings are as follows: AC15 = 4A at 440V, AC1 = 10A at 440V, AC3 = 6A at 440V, DC13 = 12W at 220V, and the maximum LR is 50A. For the gold - plated contacts, the range is 1…30 mA at 5...30V. Protection and Certification The enclosure of the pressure switch has an IP67 protection rating, providing high - level protection against dust and water immersion up to a certain depth. It has obtained a comprehensive range of certifications including ABS, BV, CCC, CCS, CE, DNV, EAC, GL, KRS, LLC CDC EURO - TYSK, LR, LVD, NKK, RINA, RMRS, RoHS, and RoHS China. These certifications attest to its compliance with international and national standards, ensuring its quality and reliability across different applications and regions. Environmental Adaptability The pressure switch can operate within an environmental temperature range of - 40 °C (-40 °F) to 70 °C (158 °F). Additionally, it can withstand a temperature of 80 °C (176 °F) for a maximum of 120 minutes. This wide temperature tolerance makes it suitable for use in a variety of environments, from cold storage facilities to industrial settings with high - temperature processes.
