Two Types: Pre-Wired Connecting Cables & Open-End Assemblies
Pre-wired M12 connecting cables have a moulded M12 connector at both ends — one male, one female — and are ready to use immediately. No termination is required. We stock three configurations: female straight to male straight (43-10564 series), female angled to male straight (43-10708 series), and female straight to male angled (43-14605 series). Available in 2 and 5 metre lengths. Use these when connecting a sensor to a panel-mount socket, a T-splitter, or another M12-terminated device where both ends already have M12 interfaces.
M12 Open-End Cable Assemblies — One Connector, Unterminated Far End
Open-end M12 cable assemblies have a moulded M12 connector at one end with free, stripped wires at the other. These are used when you need to terminate the far end yourself — for example, into a terminal block, junction box, or PLC input module without an M12 socket. We stock four variants: female angled open-end (CONEC 43-10188 / 43-10190), female straight open-end (43-10020 / 43-10022), male angled open-end (43-14436 / 43-14438), and male straight open-end (43-10104 / 43-10106). Available in 2, 5, and 10 metre lengths.
Cable Specification — What You Need to Know Before Ordering
All M12 cables and open-end assemblies in our range share the following key specifications:
Coding: A-coded — the standard coding for sensor, actuator, and I/O wiring in industrial automation. Compatible with all A-coded M12 sockets on proximity sensors, photoelectric sensors, and I/O modules.
Pin count: 4-pin (all variants). The most common configuration for 3-wire NPN/PNP sensors — carrying supply positive (+24V DC), supply negative (0V), signal output, and where applicable a fourth wire for shield or second output.
Cable jacket: PUR (polyurethane) — preferred over PVC for industrial environments. PUR offers better resistance to oils, lubricants, and cutting fluids, higher flexibility over repeated bending cycles, and a longer service life in machine-mounted and moving-cable applications. Where only general-purpose static installation is required, PVC is a lower-cost alternative (contact us to discuss options).
IP rating: IP67 — sealed against dust ingress and resistant to temporary water immersion to 1 metre for 30 minutes. Rating applies when the connector is fully mated.
Operating temperature: -25°C to +80°C (standard PUR variants).
Conductor CSA: 0.34 mm² per core — the standard for 4-core M12 sensor cables, rated to 4A per contact.
Available lengths: 2m and 5m for the pre-wired connecting cables; 2m, 5m, and 10m for the open-end assemblies (varies by part number — check individual product listings for length options).
M12 Cable, Female Straight – Male Straight (43-10564 / 43-10566)
Double-ended pre-wired cable with female M12 straight connector at one end and male M12 straight connector at the other. A-coded, 4-pin, PUR-jacketed, IP67. The most common M12 cable configuration for standard sensor-to-socket connections where both ends are in a fixed, straight-access position. Available in 2m and 5m lengths.
M12 Cable, Female Angled – Male Straight (43-10708 / 43-10710)
Double-ended pre-wired cable with female M12 right-angle connector at one end and male M12 straight connector at the other. A-coded, 4-pin, PUR-jacketed, IP67. The angled female end reduces cable strain and bending radius at the sensor connection point — the right choice when the sensor socket faces downward or when clearance around the connector is limited.
M12 Cable, Female Straight – Male Angled (43-14605 / 43-14607)
Double-ended pre-wired cable with female M12 straight connector at one end and male M12 right-angle connector at the other. A-coded, 4-pin, PUR-jacketed, IP67. Use when the male panel socket or T-box faces a direction that makes a straight cable exit impractical — the angled male end reduces mechanical stress at the panel connection.
M12 Female Angled Open-End Assembly (CONEC 43-10188 / 43-10190)
Female M12 right-angle connector with unterminated open wires at the far end. A-coded, 4-pin, PUR-jacketed, IP67. Use for connecting a sensor with a downward-facing M12 socket to a PLC, terminal block, or custom termination. Two part numbers cover different cable lengths — confirm the correct variant against your cable run requirement.
M12 Female Straight Open-End Assembly (CONEC 43-10020 / 43-10022)
Female M12 straight connector with unterminated open wires at the far end. A-coded, 4-pin, PUR-jacketed, IP67. The standard open-end assembly for wiring a sensor into a terminal block or screw-cage input module. Straight exit makes this appropriate where there is adequate clearance around the sensor connector.
M12 Male Angled Open-End Assembly (CONEC 43-14436 / 43-14438)
Male M12 right-angle connector with unterminated open wires at the far end. A-coded, 4-pin, PUR-jacketed, IP67. Use for connecting from a panel-mount female M12 socket to a terminal block or custom wiring harness, where the angled exit reduces cable bending stress at the panel.
M12 Male Straight Open-End Assembly (CONEC 43-10104 / 43-10106)
Male M12 straight connector with unterminated open wires at the far end. A-coded, 4-pin, PUR-jacketed, IP67. The male counterpart to the female straight open-end. Used when cabling from a female panel-mount socket to an unterminated termination point, or for custom harness construction where the male M12 interface is required at one end.
Not Sure Which M12 Cable Configuration You Need?
With seven CONEC variants in stock covering both cable assemblies and open-end types, the fastest route to the right product is often a quick conversation. Call us on 01536 263411 or email buddy@componentbuddy.com with your sensor make and model, cable run length, and whether you need a terminated or open far end — we’ll confirm the correct part number before you order. Average response time: 45 minutes during business hours.
