Electrical Connection; M12 Connection; Transmitter - Leuze electronic SOLID-2SF-M Original Operating Instructions

Electrical connection

6 Electrical connection
• The electrical connection must be performed by competent personnel only. Knowledge of all safety
instructions in these connecting and operating instructions is part of this competence.
• The 24 V DC ±15% external supply voltage must guarantee safe insulation from the mains voltage
and, for devices with transistor output, be able to bridge a power outage period of min. 20 ms. Leuze
offers suitable power supply units.
• The power supply must provide at least 1 A of current reserve. Transmitter and receiver must be pro-
tected against overcurrent.
• It is vital during the electrical installation that the power of the machine or system to be protected is
switched off and protected against restart, so that the dangerous movements cannot be started unin-
tentionally. The protective device may only be connected to the machine's safety circuit after all of its
safety functions have been entirely tested.
6.1

M12 connection

Transmitter and receiver are equipped with M12 connector plugs. The transmitter is equipped with a 5-pin
connector and the receiver with an 8-pin connector.

Table 6.1:
The optical transmission channel can be selected by reversing the polarity of Pin1 and Pin3. If +24 V DC
is applied at Pin1 and 0 V at Pin3, transmission channel 1 is selected. If 0 V is applied at Pin1 and
+24 V DC at Pin3, transmission channel 2 is selected.
Be sure to select the same transmission channel for both, transmitter and receiver.
ATTENTION!
For optimum shielding, connection cables where the shield is routed on the knurled nut of the
housing connector must be used (suitable cables are listed under accessories in chapter 9.3).
