4-008-40-0145 4008400145 Liquid Level Sensor SENOTEC or Homag SCM Edgebanders

Need to stop a Homag or SCM edgebander from running its glue, coolant or lubricant tank dry, or from overflowing it? This SENOTEC sensor switches at fixed level points instead of reporting a drifting float position. Part number 4-008-40-0145, cross-listed as 4008400145, with DC current, a cable with connector terminal and a white housing. It is sold as a spare for Homag and SCM edgebanders. The 4-008-40-0199 switching amplifier and the 4-008-40-0257 sensor are also supplied.

A level sensor that fails on an edgebander does not announce itself. It reads the same on a full tank as on an empty one, so the glue pot runs dry at the end of a shift, or the tank overfills and liquid reaches the chain. Most shops keep a spare in the drawer, then lose the shift anyway when it is the wrong number. This sensor sits in that loop.

The 4-008-40-0145 is a multi-point level switch made by SENOTEC, also listed as 4008400145. It does not sweep a float down a tube: it closes or opens at fixed level points, which is the two-state signal the Homag and SCM edgebander controllers read. The housing is white, and the part is catalogued as a spare for Homag and SCM edgebanders.

It runs on DC current and terminates in a cable with connector, so lead and plug arrive as one assembly. Replacement is unplugging the old lead and plugging in the new one, with no wiring work inside the cabinet. Because the plug and lead belong to the part number, that number has to match before you order.

Two related numbers matter: the 4-008-40-0199 switching amplifier is available to be provided with this sensor, and the 4-008-40-0257 sensor is supplied as well. Goods ship by DHL, FedEx or UPS; price is quoted per order.

What the part gives you, item by item:

• Multi-point level switch — switching at fixed level points rather than a sweeping float, so the controller gets a definite state at the working level.
• Two numbers, one sensor — 4-008-40-0145 and 4008400145 are the same item, so either format on a purchase list resolves to this part.
• DC current — the sensor sits on the machine's DC control circuit, alongside the level signal it feeds.
• Cable with connector — lead and plug shipped as one assembly, so a swap is 2 plug operations and no terminal work.
• White housing — a white body that stands out against dark tanks and machine frames during a walk-round check.
• Homag and SCM fitment — catalogued as a spare for Homag and SCM edgebanders, not a generic sensor trimmed to fit.
• SENOTEC brand — made by SENOTEC, the brand carried on the original sensor.
• Amplifier option — the 4-008-40-0199 switching amplifier is available with the sensor, so the signal chain stays matched.
• Second sensor option — the 4-008-40-0257 sensor is also available for machines that carry that number.
• Courier shipping — DHL, FedEx or UPS by order, so a single sensor travels as a tracked parcel.

When a level sensor fails there are two usual answers: take the machine off the line and wait for an order, or run the tank by eye and hope the glue holds. This part is the third answer.

• Order by the number on the machine. 4-008-40-0145 and 4008400145 both resolve to this sensor, so a maintenance sheet written either way still orders correctly, with no cross-reference call.
• No wiring inside the cabinet. The terminal is a cable with connector, so the swap is one plug and the machine is back in minutes rather than waiting for an electrician's slot.
• A definite level signal. Because the part is a multi-point level switch, the controller sees a clear state at the working level and the tank is caught before it runs dry.
• One brand across the line. SENOTEC is the brand on the original sensor, so behaviour after the swap matches behaviour before the failure.
• Signal chain in one order. The 4-008-40-0199 switching amplifier can ship with the sensor, which removes a second parcel and a second wait.
• A spare that covers a second machine. The 4-008-40-0257 sensor is available too, so a shop running both numbers keeps one supply line instead of two.
• Parcel freight with tracking. DHL, FedEx or UPS means one sensor moves as a small tracked parcel, not a pallet.

Either one, they are the same part. 4-008-40-0145 and 4008400145 are two formats of the same Homag number for this SENOTEC sensor; send whichever your parts list prints.

Yes, provided your machine carries 4-008-40-0145 or 4008400145. It is catalogued as a spare for Homag and SCM edgebanders, so send the machine model and the number from the old sensor and we confirm before shipping.

No. The terminal type is a cable with connector, so the lead and plug arrive as one assembly and the swap is unplug and plug.

It is a multi-point level switch. It signals at fixed level points rather than reporting every millimetre, which is the signal the edgebander controller reads.

DC current, per the part specification. That is the current type listed for this item; check it against the control circuit on your machine before fitting.

The 4-008-40-0199 switching amplifier. It is also available to be provided with this sensor, so the sensor and its amplifier can be ordered together.

Yes, the 4-008-40-0257 sensor is also available. If the sensor on your machine carries that number, order that one instead of the 4-008-40-0145.

Price is quoted per order and goods ship by DHL, FedEx or UPS. Send the quantity and the delivery country and we quote against that.
