Contacts are normally included with the D38999 D38999 series of connectors, however a number of exceptions do exist. One of them is when the part number used to order the connector has an “-LC” suffix at the end. Another exception is how the part number is assembled. Normally at the end of the part number there’s a “P” or ‘S” to denote the gender of the contacts used in the connector (“P” for pins, “S” for sockets). If these are switch to an “A” or “B”, then the contacts are again omitted and must be purchased separately. Some example part numbers are shown below.

These 2 part numbers include contacts.

D38999/20JE26PN

D38999/20JE26SN

While the 3 below do not include the contacts

D38999/20JE26PN-LC

D38999/20JE26AN

Please review the manufacture’s documentation for full ordering details as well as options for specific applications.

Photoelectric sensors consist of an emitter and receiver, the emitter sends out a beam of light for the receiver to sense. With the diffused and retro reflective type of sensors both the emitter and receiver are placed in the same housing and are configured for light to be reflected back to the sensor.

Retro reflective sensors use a target to reflect light back to the sensor and will sense an object that breaks the beam’s path. The diffuse reflective type senses an object when the light beam is reflected back to the sensor. Additional features as well as different form factors will vary from series to series.

Jim's FAQ's

Are the contacts included with the D38999 series 3 connectors, or ordered separately?

What’s the difference between “diffuse reflective” and “retro reflective” photoelectric sensors?
