LiftMaster commercial entrapment protection accessories including CPS photo eyes, edge interfaces and optical edge kits — Entrapment protection accessories page from the Logic 5.0 manual.

Short answer. LiftMaster parts identification starts with the label on the operator. On Logic 5.0 hoists the last letter (R or L) is the hand chain side. On MAXUM DC the part number spells out the model and the door weight it's built for, plus duty and voltage. Accessory part numbers like 02-103L, CPS-UN4 and TLS1CARD map to one exact item, so read them off the part before ordering.

Ordering the wrong LiftMaster part costs a second trip and a door that stays broken another day. Most of the confusion comes from look-alike photo eyes and control stations with similar numbers. This LiftMaster parts identification page lists the commercial parts from the Logic 5.0 manual accessories pages and LiftMaster's 2025 MAXUM comparison chart. Every number here comes from those two documents.

Lock out power before you pull a cover to read a label. Several of these parts sit right next to the drive chain.

Reading a MAXUM DC part number

LiftMaster prints the decoder on its comparison chart. Take JHDC12X4N4XMC as an example.

Part of the number	Meaning
JDC, RJDC, JHDC, TDC	Jackshaft, jackshaft with release, hoist, trolley
7, 12, 22	Doors up to 700, 1,200 or 2,200 lb
S or X	Standard duty or extended duty
1	120/240 V single and three phase
4	480 V three phase
B	Battery backup capable (standard on the JDC)
N4X	NEMA 4X environmental version

RJDC units end in BER or BEL, which is the right or left hand version. NEMA 4X units ship with the CPS-UN4 eye instead of the CPS-U.

LiftMaster MAXUM JDC jackshaft operator, part number family JDC7S1BMC and JDC7S4BMC — The JDC. Its part numbers start JDC7, for doors up to 700 lb.

Hoist handing on Logic 5.0

H and HJ operators are ordered right or left hand, and the last letter of the model number shows it. The 3 HP GH is the same. On GH units from 1/2 to 2 HP the hand chain wheel can be switched in the field, so the letter matters less.

Control stations

Part	What it is
02-101	1-button control station, steel enclosure
02-102	2-button control station, steel enclosure
02-103L	3-button control station, steel, with Maintenance Alert LED
02-110	Key control station, indoor flush mount, NEMA 1, with stop button
02-401	1-button indoor surface mount station, NEMA 1

The 02-103L is the station with the MAS LED, and it needs the fifth wire to light. People often look for an 823LM as a wall button. The 823LM is a remote light switch and it's discontinued, so the 02-103L is the station to order.

Photo eyes and edges

Part	What it is
CPS-U	Dual sided infrared photo eyes, NEMA 1, indoor, 30 ft
CPS-UN4	Thru-beam photo eyes, NEMA 4, indoor or outdoor, 45 ft
CPS-RPEN4	Retro-reflective with polarized reflector, NEMA 4X, 50 ft
CPS-OPEN4	Dual sided with flexible housings, NEMA 4X, 45 ft
CPS-MEI	Interface for approved 2-wire monitored edges
CPS-EI	Interface for approved 4-wire edges
CPS3CARD	Plug-in card for a second monitored eye or edge
OES-SD16, OES-SD24	Optical edge kits for sectional doors, 16 and 24 ft
OES-RD16	Optical edge kit for rolling doors, 16 ft
65-8202, 65-5202	Pneumatic sensing edge kits, non monitored

The optical edges are NEMA 6 rated and run to 33 feet. The rubber cuts to length. Wire colours and terminals for each eye are on the entrapment protection guide.

LiftMaster 02-101, 02-102, 02-103L, 02-110 and 02-401 control stations with 811LM and 813LM remotes — Control stations and remotes as listed by LiftMaster, with the STAR1000 receiver.

Option cards and add-ons

The TLS1CARD timer light status card can flash lights or sound a horn at set door positions. It adds timer functions too. The AUXCARD has normally open and normally closed contacts that change state with the door's motion. A red and green traffic light, the RGL24LY, shows when the door reaches open, and LiftMaster recommends the TLS1CARD with it. The 50-HERK2 is a 24 V microwave motion detector with two channels. The 50450 is a NEMA 4 sectional door interlock switch that disables the controls when the door is locked. A wrong card triggers the 6 blink code on the Logic 5.0 error codes page.

Parts that don't exist

Some numbers float around online that LiftMaster doesn't list. We won't quote parts for codes like PSLV1, LMWIFI890, 821LMCS or a "Techna Pro". The 380UT is marked discontinued on its own LiftMaster page. Bring us a photo of the label and we'll find the current part.
