Ueda Seisakusho PM-60 Series Pressure Switch

Manufacturer: Ueda Seisakusho Co., Ltd.
Model : PM-60 series

Features

The PM-60 series is ideal for indoor locations that require dustproofing and drip-proofing, and like the PM-50 series, it has a built-in microswitch in the contact area, making it suitable for situations where you want to set a narrow opening and closing pressure difference (ON-OFF width).
For DC use with a large current, a DC microswitch is built in.
The pressure receiving part uses a metal bellows (phosphor bronze or SUS316), and the snap action switch with fewer malfunctions and variations and the quick action mechanism at the end of the main operating lever make this a highly reliable pressure switch with less accumulated error.

*PM-606 and PM-607 are for high pressure control and the standard material for the pressure receiving part is stainless steel (SUS316).

(A)	50 = Indoor general-purpose type 60 = Indoor pressure-resistant / drip-proof type
(B)	3 = Pressure adjustment range (refer to specifications table)
(C)	No symbol = Built-in micro switch (standard product) DC = Built-in micro switch for low voltage and micro current DC10 = Dedicated built-in micro switch for high voltage DC
(D)	R3 = Connection diameter R 3/8 (PT 3/8 thread) ※Standard G3 = Connection diameter G 3/8 (PF 3/8 thread) F6 = Connection diameter ø6 mm copper pipe with flare nut ※Note 1, Note 2
(E)	No symbol = Bellows housing material: Phosphor bronze + nickel plating S = Bellows housing material: Stainless steel (SUS316)
(F)	No symbol = Without main body mounting bracket B = With main body mounting bracket

Note 1: The material for the connection part is only available in phosphor bronze specification.
Note 2: When the connection part is a φ6 flare type, the specification will be with main unit mounting bracket (with bracket).
