I/O circuit diagram
Notes:
1)Make sure to connect terminals correctly as the sensor does not incorporate a reverse polarity protection circuit.Further, the output is not incorporated with a short-circuit protection circuit. Do not connect it directly to a power supply or a capacitive load.Faulty wiring may result in damage.
2)The color code of the connector attached cable is also the same.
3)Ensure to insulate the unused output wire.

------------------------------ Tab6 showing ------------------------------
Mounting
- When fixing the sensor with screws, use M3 screws and the tightening torque should not exceed the values given below.
Further, use small, round type plain washers (ø6 mm ø0.236 in).
| Model No. | Tightening torque |
|---|---|
| PM-□44(P) | 0.5 N·m |
| PM-□54(P) |
Cable extension
- Cable extension is possible up to an overall length of 100 m 328.084 ft with a 0.3 mm2, or more, cable.
However, since a voltage drop shall occur due to the cable extension, ensure that the power supply voltage at the end of the cable attached to the sensor or at the sensor terminals is within the rating.
But, when the overall cable length, including the cable attached to the sensor, is as given below, there is no need to confirm the voltage.
| Conductor cross-section area of extension cable | Total cable length |
|---|---|
| 0.08 to 0.1 mm2 | Up to 5 m 16.404 ft |
| 0.2 mm2 | Up to 10 m 32.808 ft |
| 0.3 mm2 | Up to 20 m 65.617 ft |
Others
- Since the sensor is intended for use inside machines, no special countermeasures have been taken against extraneous light. Take care that extraneous light is not directly incident on the beam receiving section.
- Do not use during the initial transient time (50 ms) after the power supply is switched on.
PM-□54 PM-□54P
(1) Strip the cable sheath 15 mm 0.591 in, or more, and insert the wires into the connector insertion holes till the wire tips reach the end.
(2) When unplugging, give as much stress as a connector lug can be relieved from a hook. Then unplug it.
Caution: Be sure to hold a connector when plugging or unplugging it. Do not hold a terminal or a cable when plugging or unplugging the connector. Otherwise, it will cause a poor contact.
Soldering (Both connector CN-14 and sensor)
- If soldering is done directly on the terminals, strictly adhere to the conditions given below.
| Soldering temperature | 260 ℃ 500 ℉ or less |
|---|---|
| Soldering time | 3 sec. or less |
| Soldering position | Refer to the below figure |
Crimping of hook-up connectors CN-14H and CN-14H-2
| Item | CN-14H | CN-14H-2 |
|---|---|---|
| Conductor cross-section area | 0.08 to 0.2 mm2 (AWG28 to AWG24) | 0.18 to 0.22 mm2 (AWG25 to AWG24) |
| Wire diameter | ø0.7 to ø1.2 mm ø0.028 to ø0.047 in | ø1.2 to ø1.52 mm ø0.047 to ø0.060 in |
| Wire insulation material | Vinyl chloride or soft polyethylene | |
Crimping method
(1) Strip the cable sheath 15 mm 0.591 in, or more, and insert the wires into the connector insertion holes till the wire tips reach the end.
(2) Crimp with the exclusive hook-up pliers CN-HP.
Notes:
1) When attaching or detaching the connector fitted with a cable, make sure to hold the connector firmly before proceeding.
2) After crimping, do not pull on the cable.
Caution:
Make sure to use the exclusive hook-up pliers CN-HP. Commercially available pliers cannot be used.
- Prior to using the sensor, affix the cable in a way as to avoid direct stress on the crimped part.
