Coils for solenoid valves

The coils are specially designed to operate in
the aggressive environment of high humidity
and temperature uctuations that you nd in
most refrigeration systems.

The Clip-on fastening system ensures a
faultless installation and makes the coils easy
to mount and dismount. A Danfoss Clip-on
coil can be mounted without any tools at all,
and it is simple to dismount the coil by means
of a screwdriver.

Features • Encapsulated coils with long operating

life, even under extreme conditions.

• Standard coils for a.c. or d.c.

• Standard coils available with 3-core

cable, terminal box or DIN plugs.

• Standard coils from 12 V to 420 V, 50,

60 or 50/60 Hz.

The Clip-on coils are available for the
entire range of Danfoss solenoid valves for
refrigeration, freezing and air conditioning
purposes.

• Standard coils dimensioned for max.

opening dierential pressure (MOPD)
of up to 21 bar.

• Coils can be tted without the use of

tools.

Technical data

Connection

Ambient temperature

10 or 12 W a.c. coil for NC (normally closed) valve:

-40 − +80 °C ­10 W a.c. coil for NO (normally open) valve:

-40 − +55 °C
20 W coil for NC and NO valve:

-40 − +50 °C

Permissible voltage variation

10 , 12 and 20 W a.c. coils: +10 − -15 %
Double frequency coils and 20 W d.c. coils: ±10 %.

3-core cable

The external thread in the screwed cable entry
suits exible steel hose or corresponding cable
protection.

Terminal box

Leads are connected to terminal screws in the
terminal box. The box is tted with a Pg 13.5
screwed entry for 6 − 14 mm cable.
Max. lead cross section: 2.5 mm2.

Enclosure

IP 67 with cable or terminal box
IP 20 with DIN plugs and protective cap
IP 65 with DIN socket
IP 00 with DIN plugs.

Approvals

See under the required solenoid valve.

DIN plugs

The three pins on the coil can be tted with spade
tabs, 6.3 mm wide (to DIN 46247).
The two current carrying pins can also be tted
with spade tabs, 4.8 mm wide.
Max. lead cross section: 1.5 mm2.
Use of the protective cap supplied will prevent
inadvertent contact with live parts.

DIN socket

(to DIN 43650)
Leads are connected in the socket. The socket is
tted with a Pg 11 screwed entry for 6 − 12 mm.
