B-LINE 1273A-300 – Frequently Asked Questions
1) Is the B-Line 1273A-300 sensor head a through-beam type, and does that mean I need two of them?
The 1273A-300 is a through beam detector, so it works as a detector paired with a separate emitter aimed at it across the opening. The beam is broken by the target passing between the two halves. If you are replacing only the receiving side, this head covers that half; a standalone reflective or diffuse sensor will not drop into a through-beam alignment.
2) Can the B-Line 1273A-300 photoelectric sensor head be used in a washdown or wet area?
Yes. The head carries a NEMA 4, 6 and 13 environmental rating and a stainless steel enclosure, which covers hosedown, temporary submersion and oil or coolant spray areas. That combination is what you want in food processing, car wash, and machine tool applications rather than a plastic-bodied general purpose sensor.
3) How is the B-Line 1273A-300 wired in, and does it need a connector or a field-attached pigtail?
It comes with an integral cable terminated in female spade terminals, so there is no connector body to buy and no field termination at the head. You land the spades on the amplifier or control block terminals. If your existing run uses a quick-disconnect barrel plug, this one will not mate with it without changing the termination at the control end.
4) What is the temperature range on the 1273A-300 sensor head, and will it survive a freezer or an oven line?
Rated -40 to 176 degrees F (-40 to 80 degrees C). That covers blast freezer and cold storage duty at the low end and warm process areas at the top, but it is not an oven or furnace-mouth sensor. Note the cable is PVC jacketed, so route it away from hot surfaces even where the head itself is within range.
5) How long is the cable on the 1273A-300 sensor head? I need to reach a control panel across the room.
The attached cord is 108 feet, which is long enough to run from the sensing point back to a remote amplifier or panel without a junction box or splice in a washdown zone. That matters on a NEMA 4 or 6 install, where every added splice is another sealing point.
6) Is the B-Line 1273A-300 a complete sensor or just the sensing head?
It is the sensor head only, one half of a through beam pair, with the cable and spade terminations for connection back to the controlling amplifier. Plan on the matching opposite head and the amplifier or control being separate line items when you build the order.
7) What is the exact part number to order this B-Line photoelectric sensor head?
Order it as B-Line 1273A-300. That is the single model for this stainless steel through-beam head with the 108 foot PVC cable.
